Light-Motion combination switch

Light-Motion combination switch

GE/Jasco released a new Z-wave certified switch in Dec 2016, which was made available on Amazon in April 2017. There was no press release or announcement and many people don’t even know that such a switch even exists hence my blog posting here.

The smart hub community quickly jumped on that in Feb 2017 requesting support and given the wide support of GE switches across many smart home hubs, this switch has been integrated rather quickly (Pulse, Trane, Wink, Nexia, Honeywell, HomeSeer, Smart Security, Harmony, Vera, Smartthings and Connect).

What’s the use case for this switch? Before this switch was released you could buy a Z-wave light switch (on/off or dimmer) and then you had to buy a motion sensor separately. As an example you would install this switch in your bathroom/toilet room and then you had to install a motion sensor somewhere in the same room.

Unless you have a power outlet close and a clunky power supply in that outlet to power your motion sensor, you would have to buy a battery operated Z-wave motion sensor or use a USB outlet and wire the motion sensor with a USB cable. Most people went with battery operated motion sensors which have a standard of 4 min timeout setting to preserver battery life.

This setup required you to purchase the light switch and the motion sensor separately which costs anywhere from $35 to $45 for the switch and $20 to $35 for the motion sensor for a total of $55 to $80 dollars.The new GE26933 combination switch is selling for $55 dollars which is a very reasonable price for a combination of both.

The beauty of having such a combination switch is that the motion sensor is not battery operated and the hassle with wakeup and timeout settings doesn’t apply. As a result you can configure this switch on a very granular level and you don’t have to worry about wires coming from your motion sensor to your outlet trying to have a permanently powered motion sensor like the GE 6 in 1 sensor, which is a great product by itself.

You have a single switch combining motion and light switch into one device. In addition it is a dimmer so you can adjust the brightness above and below the actual motion window of the switch. This switch also supports “Last level” which means when you use the dimming function to lower the brightness to e.g. 50% the next time you power on those lights, it will be at 50%.

This switch comes with a variety of options you can configure via Z-wave settings. You have 19 parameter settings you can use to adjust this switch ranging from Timeout duration e.g. 5 min (default) to 30 min or no timeout, motion sensitivity from high to low with medium being the default, Light sensing on or off to the most important parameter which is operation mode with manual, vacancy or occupancy. You can find more details for those parameters here https://products.z-wavealliance.org/products/2108/configs

For smart home hub integration you switch to manual and your smart home hub will detect 2 Z-wave devices. The actual light switch and the motion sensor enabling you to create now scenes or events based on those devices or other devices from your smart home hub.

 

Most bathroom/toilet rooms have a fan switch right next to the light switch. You can now configure an event where you specify things like

if motion detected

turn on lights and turn on fan

for 5 minutes

and then turn off lights and fan

When you integrate your GE26933 switch into your smart hub system make sure to properly save those parameters e.g. Homeseer settings on the picture. Even before you set those parameters your smart hub system should find 2 devices (switch and motion) but motion will not change status as the default parameter setting for this switch is occupancy with 5 minutes.

The other benefit of having a permanently powered motion sensor is not having to deal with any wakeup and timeout values. You can go as low as 1 minute intervals for this light switch. If your switch is facing the restroom toilet with a setting of 1 minute unless the person sitting on the toilet doesn’t move for 60 seconds, will reset the timeout value continuously but again this is adjustable up to 30 min as needed.

In summary, many smart home owners were requesting for years a combination switch from the vendors and GE finally delivered and hopefully more vendors will follow. This switch can be used in many use cases ranging from garage lighting leveraging the daylight sensor to restrooms with no light or window allowing you to configure your room and lighting what fits your needs the best.

The price is very reasonable and totally justifies switching from two separate devices to a single device with the additional benefit of not having to deal with batteries and wires and two separate devices. Great addition to the Z-wave family of light switches from GE and I hope my blog post sparked some ideas for you on how to improve your smart home even further. Personally I already installed two of those at my home and I am going to add more.

Connected Home vs Smart Home

Connected Home vs Smart Home

People believe “smart homes” and “connected homes” are the same. You might even see terms like “true smart home”, where companies try to bring their point across of having a home, which is more than an assembly of connected devices. Let’s look into those terms and define, what a “smart home” really is.

Let’s start with the official definition outlined by Wikipedia. Smart House on Wikipedia refers to Home Automation. Within Home Automation you will find the following definition.

“Home automation or smart home (also known as domotics or domotica) is the residential extension of building automation. It involves the control and automation of lighting, heating (such as smart thermostats), ventilation, air conditioning (HVAC), and security, as well as home appliances such as washer/dryers, ovens or refrigerators/freezers. They use Wi-Fi for remote monitoring and are a part of the Internet of things. Modern systems generally consist of switches and sensors connected to a central hub sometimes called a “gateway” from which the system is controlled with a user interface that is interacted either with a wall-mounted terminal, mobile phone software, tablet computer or a web interface, often but not always via internet cloud services.

The key word here is “automation”. Putting so called “smart devices” into a home doesn’t make the home smart. The industry is using the term “smart” for devices, which can be controlled by a smart phone, tablet or nowadays voice control devices like Amazon Echo or Google Home. Another example would be the trend of smart doorbells. Just because a doorbell will notify you on your cell phone, emails or texts you or allows you to speak to your visitor from your cell phone with two-way audio, doesn’t mean you have a smart home.

I created the following picture to demonstrate one example home with smart devices and then I will go into the details with real life use cases/examples of what would make this home a “smart home”.

Smart Home

You can see a lot of devices within this “smart home” ranging from thermostats, speakers, media and entertainment, etc. Most or all of those devices can be controlled from a smart phone, tablet or Alex Echo / Google Home with individual apps or skills (as Amazon calls them). They don’t have to be necessarily have to controlled by a single home automation hub/controller/gateway.

With that said, let’s provide some examples, where the true benefit of having a home automation hub/controller/gateway will showcase, what a “smart home” should look like, otherwise this home would simply be a “connected home”.

Geo Fencing

The most common use case is GEO fencing. GEO fencing is the term for location aware reaction of your home automation system.

geo fence In this example you create either one or two virtual fences around your home. The first fence is very close proximity e.g. 100 to 200 feet to capture if you leave your home. The second fence could be a couple of miles.

Most people go with one fence only but others go with a second one to e.g. set the temperature of the home to a more comfortable setting so by the time they get home, the house is nice and cool or warm and cozy and if it is night, turn on the lights in certain areas of your home and open the garage door, when you approach the inner perimeter.

Yes, you could use your cell phone and open your Nest or Ecobee app, while you are driving, and set the temperature to the desired level. You could press the button in your car to open the garage door, when you are in front of it. The Geo fencing feature does all that for you based on logic you defined and if any delay occurs like traffic jam on the highway, you wouldn’t have to worry about opening your app and changing states of your smart devices.

Disaster Prevention

Less known, but very efficient and effective example is the combination of water shut-off valves and water leak sensors. In the old days you could buy a system, which connected to a telephone line and if the water leak sensor detected a leak, it called out and notified specific people. Those systems were expensive in up front cost and in some cases they charged monthly fees for that service.

In addition to that, the sensors were limited in terms of how many of those sensors could be installed and how long those wires could have been. Those costs and limitations prohibited a wide deployment of such notification systems.

With today’s technology, the picture has changed drastically and situations like on the picture should be a thing of the past. As many wireless water leak sensors you need communicating with your central hub/controller/gateway and in case of a flood the “smart home” will take action, which can be a simply notification via email or text, announcement within the house over all speakers, alarm sirens, etc the options of actions is very long.

This example doesn’t prevent any flooding, but it will take action at the slightest amount of water reaching the water leak sensors, which can prevent coming home to a completely flooded basement. Those costs will run in the thousands of dollars and the best of this whole example is: “Insurance companies will give you a discount, if you install water leak detection systems in your home”. Simply ask your insurance and they will tell you what discount you will receive, if you chose to implement this example.

This applies to home owners and landlords. The investment of having such a system implemented can be recovered after several months or years. Example would be a 10% discount for a home owner insurance of $1,500 per year. Those savings of $150/year would give you a break even point from your investment of 2 or 3 years, not to mention the cost savings of not having to repair a flooded basement or laundry room, which typically range in the area of $3,000 to $5,000 or more.

Energy Control

Another example would be energy control of your home. You could have remote controlled blinds, fans and thermostats in your home. You could use your cell phone, smart tablet or voice to turn those “connected devices” on as needed. A true “smart home” would do the following and this is just one example, which can be adjusted to any need or location…

IF summer AND IF morning AND IF temperature reaches 75 degrees –> THEN lower blinds

IF summer AND IF morning AND IF temperature reaches 75 degrees AND blinds lowered –> THEN turn on ceiling fan

IF summer AND IF morning AND IF temperature reaches 75 degrees AND blinds lowered AND ceiling fan is ON –> THEN power on air condition

In simplified text, this logic does the following. In the morning, when the sun rises, the temperature in your house rises as well. Most households have their thermostat set to a certain temperature, before the air condition kicks in. Even if they have smart thermostats, they will get trigger by a certain temperature.

The example logic above delays the air conditioning kicking in by using the alternative methods of blocking out sun or using ceiling fans first before the more power hungry and costly air conditioning system kicks in. The “smart home” will try to block the sun first by lowering the blinds. If the temperature still rises, then the “smart home” will turn on the ceiling fan. Only if all that isn’t enough, then it will turn on the air condition.

Security and Fire Alarm

The top rated reason for people adopting “smart home technology” is security. The security industry has been around for many years and alarm systems have evolved in many directions over the years. Security systems today include not only window/door sensors, glass break and motion sensors, but also fire alarm detectors and cameras with motion alarm.

Having those notifications going to a service provider, who will call the authorities is a good thing. However, nobody has thought about the actual home owner in those situations. To be more specific, image a fire alarm going off in your home. The sirens will go off, you might get a call from your service provider and the whole family will be up in no time. What is not considered is, how to make this situation easier and less stressful.

Imagine the same scenario, but in this case once the alarm goes off, the lights in the whole house will go on or change color to e.g. red, the blinds will open allowing a clear view from the outside into the house for the firemen, the alarm system will disarm after the authorities have been notified (last thing you need is your alarm system sirens going off just because you or your family opened the door and you forgot to enter the code to disarm the alarm system), the door locks will unlock allowing easy exit of the house, the speakers throughout the whole will announce that there is fire and with the right equipment it can also announce, where in the house fire has been detected. If nobody is home, the home owner will get notified via email, text or phone call from the service provider and from the smart home and having the doors unlocked will allow easy entry into the home for the firemen.

In summary, there is nothing wrong with having a “connected home”. As a matter of fact a connected home is the first step towards a smart home. Yes, it requires some adjustment and logic to be put in place, before a connected home becomes a smart home. The time is worthwhile investing, as the return of the investment will be worth it.

The additional cost of making a connected home to become a smart is much lower compared to making a regular home to become a connected home or smart home. The only challenge with this transformation from connected home to smart home will be the interoperability between the smart devices and the hub/controller/gateway, as not all vendors will support all smart devices.

In some cases workarounds are available and yes, you could use something like IFTTT (If this then that) to create logic for your connected home. IFTTT has a wide variety of supported devices (channels), but you should consider always the worst case, which is when your home might not have any internet connection. Some home automation hub/controller/gateway vendors require an internet connection to be available to conduct any actions in your home, which might not be a good thing in some of the use cases and examples outlined above including IFTTT.

The smart home adoption is at an all-time high and I encourage everybody to invest the time to find the most suitable technology for their homes and families and aim for a true “smart home”.

 

 

Hinge Pin vs Strips for Door sensors?

Hinge Pin vs Strips for Door sensors?

Two new Z-Wave Plus Door sensors have recently hit the market.

The GE Hinge Pin Smart Door Sensor is the latest. But, is it the greatest? It looks like a door hinge, and attaches like one too making it discreet. It has remote monitoring that will alert your smart phone or tablet if door is opened or closed. Scenes can also be set up to turn the lights on or off. For example, if the door is opened turn on the lights. It really is a nice feature to come home to.

Door Hinge
Strips

Strips by Sensative is the other new Z-Wave Plus door sensor on the market. It’s a white strip about a half and inch wide and about as long as a pencil that is placed on the door or window. It works with magnets to trigger if opened or closed.

Strips can do everything the Hinge Pin can do and more, but have a different look, so it really depends on personal preference. One advantage Strips have over the Hinge Pin is it can be used to monitor windows as well as doors. The Hinge Pin is a door only device.

Strips also claims to have a 10 year battery life compared to the Hinge Pin’s relatively short 2 year battery life. However, it is important to note the Hinge Pin’s battery can be changed after 2 years. There is no way to get into Strips to change the battery, so after 10 years when the battery stops working it has to be thrown away and replaced.

So, how does the GE Z-Wave Plus Hinge Pin Smart Door Sensor Compare with Z-Wave Plus Strips by Sensative?

Both the Hinge Pin and Strips are winners depending on individual preference and need. However, while the Hinge Pin may have a slight aesthetic advantage over Strips, Strips definitely wins the prize for utility and longevity. A 10 year battery life is pretty impressive. And, Strips are weatherproof!  The Hinge Pin has limits, but is a tad less expensive.

Below is a comparison chart comparing the two feature to feature.

Strips

$55
  • Remote Smartphone Monitoring
  • Ability to Trigger Scenes
  • Activity Alert to Smartphone
  • Able to use on Windows
  • Works with Cupboards and drawers
  • Can be used on Doors
  • Battery Life of 10 years
  • Weatherproof for Outdoors
  • Easy Setup
  • Barely Visible and Discreet

Hinge Pin

$40
  • Remote Smartphone Monitoring
  • Ability to Trigger Scenes
  • Activity Alert to Smartphone
  • Able to use on Windows
  • Works with Cupboards and drawers
  • Can be used on Doors
  • Battery Life of 10 years
  • Weatherproof for Outdoors
  • Easy Setup
  • Barely Visible and Discreet

There are many reasons someone might want to monitor door and window activity in their home. The top reason is, of course, security. It’s important to make sure the kids aren’t snooping in your bedroom, or simply to know when someone has entered your home, through a door or window if there are no cameras in place. Even with cameras, the added security, piece of mind and use possibilities these devices add to our lives make them welcomed and valued new members of the Z-Wave Plus family.

 

 

 

Smart Homes at IoT World (Part 2 of 2)

Smart Homes at IoT World (Part 2 of 2)

IoT World

Internet of Things World 2016 was the 3rd annual event hosted at the Convention Center in Santa Clara CA. With over 10.000 attendees and over 200 exhibitors you were able to attend a total of 15 dedicated tracks around IoT ranging from manufacturing to smart cities, connected cars, the smart home, healthcare, energy & agriculture, supply chain & logistics plus much more. This is the second and final post of a two part report focusing on “The Smart Home” track from this event.

This report will cover new upcoming technologies, expert opinions shared at panels from various industry experts and interesting startups to look out for in the coming near future. This second part will focus on new innovations and enhancements of smart home devices.

sevenhugs-smart-remote-05219One of the most innovative products at this IoT event relevant to smart homes is the Sevenhugs “Smart Remote Control”. This touch remote adjusts to the device you are pointing at. In other words, you point at your Nest thermostat it will offer you a slider to adjust temperature up and down but when you point at your Philips Hue bulb it will change the menu to turn on/off and dim the light bulbs.

Talking to the Sevenhugs crew gave me some very good ideas as this remote is able to run HTTP/HTTPs commands. This could make the integration into Vera a breeze but I don’t want to judge until I can get one of those devices into my hands.

This device is not available today and they are aiming towards the end of this year to release that product to consumers. More information about this device can be found under http://remote.sevenhugs.com/

Chui

Another very interesting product called “Chui” got my attention. There are a variety of smart door bells out there already and more coming out. You can buy today Skybell, Ring, etc and soon you can buy a product called Remobell. They are almost the same in terms of features and functions while their designs might differ.

However, Chui is different. Chui is face recognition combined with your door bell. It will be able to perform certain tasks mapped to each user profile. As I outlined in my part 1 of my report Role Based Access Control (RBAC) is something which is desperately needed in conjunction with voice control and voice authentication but in this case RBAC is part of the product by mapping scene or tasks to a specific user e.g. Dad comes home and the door unlocks, the temperature goes to 74 degrees, the lights go on and dim to 50%.

Another benefit of Chui applies to the use case of dog walkers, cleaning lady or babysitters who need temporary access to your home at certain times. With smart locks using a key, you have to give them a key which defeats the purpose of having a smart lock. With smart locks using a code, you give them a code which can be used by anybody if they get their hands or eyes on that code. With face recognition user pictures will be stored and authenticated and then mapped to their user profile.

Very interesting concept and sounds very promising. Talking to their CEO he confirmed that they have taken a different approach and that they are taking security very serious. More details and pre-orders can be placed under https://www.getchui.com/

EnHuv_switch

Changing from security to the lighting world. This product showcased in the startup arena of the IoT event got my attention. The sleek look and simple functionality while offering a wide variety of functions and compatibility made me take a deeper look at their product. The EnHuv light switch replaces single, two or 4 gang switches.

They are targeting $99 for the single and $179 for the 2-4 gang switch as their end consumer price. This is double the price of e.g. a Z-wave switch. However, a Z-wave switch is able to power on/off your lights or dim those lights. If you are using smart bulbs you have to use your cell phone app to start a specific scene or change the color of the lights.

This switch is a sleek looking and powerful device allowing you to control your lights from Philips, Wemo, etc and power on/off, dim, change colors in a simple interface which everybody understands. Talking to the team it became obvious that they have experience in that space from previous jobs and they are using that knowledge for this product development. I did ask what protocols they are or will support with that light switch and their answer was Z-wave, ZigBee, WiFi and Bluetooth.

ThisEnHuv_Setup product is not available today and no exact date was given to me but when I pushed they said that they should launch this year. That product can be compared with the Aeotec Touch Panel light switch which requires a Z-wave module behind it. This EnHuv light switch product has A) more functionality in terms of functions to apply B) more protocols Wifi, ZigBee, Z-wave, etc and C)  a much higher price.

Time will tell if people are willing to invest double the price of a Z-wave switch/dimmer to obtain better and more functionality with a sleek design or if they will stick to their cell phone apps or pre-saved scenes of their home automation controller.

I also verified if their product requires an e.g. Philips Hue Bridge to work and their answer was that they don’t but if you do use the Philips Hue bridge, you would have much more functionality to choose from so they recommend using that bridge.

Having the ability to utilize existing scenes stored on the Philips Hue bridge would allow everybody to have consistent scenes on their cell phone app, their home automation controller and the EnHuv light switch. Their website is still in development but more detail can be found under https://enhuv.com/

GreenWave

Being on the subject of scenes I visited the booth of Greenwave systems. That company received one CES award in 2015 and I was curious about their product offerings and their portfolio. I have to say that I was amazed about their concept and their implementation.

Greenwave systems has taken scenes to a whole different level. Their product allows interaction with Amazon Echo aka Alexa and use natural language like speaking to a person instead of predefined commands. But this is not the only thing they can do. They allow the end user to create “tags” and map smart devices to those tags.

Example would be to create a tag called “Living room” and add devices like Sonos, Lights, Motion sensors, etc to that tag. The end user can then trigger that tag. On top of that the end user can create scenes on the fly e.g. he tells Alexa to create a scene called “Movie” and then record in order certain tasks e.g. 1) dim lights to 50% by using the earlier created tag, turn on TV, set thermostat to 76 degrees and then save this scene called “Movie”. The user can then run that scene by triggering it via Alexa. Modification of any scene is a breeze as the end user can simply add kitchen lights to the tag “Living Room” by adding e.g. a table lamp to the tag “Living Room”.

In a nutshell the Greenwave system solution enables scene management via voice control. I would classify this as dynamic scenes of Greenwave Systems vs static scenes from your home automation controller. Unfortunately Greenwave systems only works business to business and not business to consumer. More company details can be found under http://www.greenwavesystems.com/

kuna_outdoor_security_light_t

A different approach has been taken by the company Kuna. Kuna released last year an outdoor light with a camera and two way audio communication. People have been asking for an open API to integrate that product into their home automation controller systems. Talking to a Kuna representative he explained that they are consider their product a security system which is why they embedded a siren into their product and cloud features to enable recording and historical view for the end user and other features to support their endeavor.

Sounds like a video doorbell system but it isn’t. They are considering their product a secure ecosystem and opening that up could weaken that security concept. They didn’t say no to an open API but given the latest news on e.g. Smarthings hub security vulnerabilities from 2 weeks ago and the gmail exploit on the Samsung fridge from Aug 2015 feeds the argument not to open up their product to other ecosystems.

More information on Kuna can be found here https://www.getkuna.com/

Connected Food

I also want to raise awareness of a new initiative between Pirch and Innit. They are launching on May 19th a showroom just like the Target smart home demo location in San Francisco ( http://openhouse.target.com/ ) but the main difference here will be that they will be showcasing smart appliances combined with the Pirch concept of having famous cooks working and demoing those appliances and their value add.

I am looking forward to some more details on this as Kitchen Home Automation use cases are limited today and more education is needed.

shopping

Last but not least I would like to share some data points shared by industry experts during panel discussions. One interesting study was performed last year where a test was conducted on 10.000 people where some articles were labelled with “Connected” to see if this would change their buying behavior.

The results were very interesting. Only 5% of the 10.000 people actually looked at the higher priced product. Of those 5% only 5% actually looked and read the “Connected” spending more time with the product.

My personal opinion is that most people didn’t even understand what “Connected” means. If I would see e.g. a crockpot saying “Connected” I would not assume that this product has WiFi or other connectivity. On the other hand the word “Smart” has already been used so many times over so many years that putting the word “Smart” into the list of features wouldn’t help either to identify a “smart product” which integrates into a smart home. Calling any product “IoT enabled” would make things worse as no average consumer would even understand what IoT means.

Overall a very interesting and educational event and I am looking forward to the Smart Home Summit in Nov 2016 in Palo Alto CA.

Smart Homes at IoT World (Part 1 of 2)

Smart Homes at IoT World (Part 1 of 2)

IoT World

Internet of Things World 2016 was the 3rd annual event hosted at the Convention Center in Santa Clara CA. With over 10.000 attendees and over 200 exhibitors you were able to attend a total of 15 dedicated tracks around IoT ranging from manufacturing to smart cities, connected cars, the smart home, healthcare, energy & agriculture, supply chain & logistics plus much more. This is the first of a two part report focusing on “The Smart Home” track from this event.

This report will cover new upcoming technologies, expert opinions shared at panels from various industry experts and interesting startups to look out for in the coming near future.

garage door controlledA new study on year 2015 analyzed the usage of smart devices and the results are pretty interesting. The most “used” smart devices of year 2015 was the “smart garage door”. The smart garage door opener concepts implemented are ranging from adding Z-wave relays and tilt sensors to their existing home automation hub, to adding “connected” garage door openers which connect to existing home automation hubs, to independent systems with simple apps on customers’ phones, to the latest trend which is Alexa (Amazon Echo) connected garage door openers.

smart_doorlock

The second most used device in year 2015 was the smart door lock. The trend for those devices is going towards ease of installation. People are shying away from having to take apart the whole door lock mechanism and replace all the guts of a door lock, to install a brand new smart door lock. The customers are leaning towards removing two screws and adding on a new smart door lock leaving the existing locking mechanism in place.

Interestingly enough, the Bluetooth managed door locks did not get the expected market adoption and instead WiFi or Z-wave door locks dominated the market. It was great to hear that “Alexa connected” was not a trend as Amazon’s Echo does voice recognition and not voice authentication which are two completely different things.

voice

Two discussions evolved in regards to voice control of smart homes. The first one was the difference between voice recognition which is a device understanding what you are saying and executing the command versus voice authentication, where the device doesn’t care what you say but instead the devices recognizes that you are really you and not somebody else.

voice-security

The second discussion about voice control was around cloud based vs offline voice recognition. On this subject the opinions were shared across the audience, that nobody wants to loose voice control over their smart home just because their internet provider has gone offline. The voice control service should always be available with the house being online or offline.

Artik_10

Amazon Echo aka Alexa only functions in online mode of the house. Samsung showcasing their new Artik technology at this event, had their Artik 10 device powered by Sensory as a demo. This device works in offline mode of the house and executes voice commands just like Alexa. The Artik 10 just started selling on DigiKey and is already sold out and now on back-order. Details on Artik can be found under http://www.artik.io 

At $150 for the Artik 10 the price is more than double the price of a Raspberry PI 3 Ultra Kit. Supported OS versions are Fedora, Snappy Ubuntu Core and Samsungs Tizen. More importantly Artik 10 supports Z-wave, ZigBee and Brillo with Bluetooth Mesh and Weaves coming this year. Adding those protocols to Raspberry PI 3 will certainly increase the price significantly. The expectation of people is that comparisons will be made but one major advantage of Raspberry PI over Artik 10 is their developers network. Artik will launch their Apps platform for developers within 3 months from today and people are already lining up to join that initiative. Artik will charge a developer fee just like Apple does to join their Apps platform.

Artik_10_use_case

As a live demonstration the Samsung Artik team showed a robot being voice controlled by their sensory voice control chip running on the Artik IoT framework. They also showcased a security system which included a home automation controller hub, motion sensor, etc all being controlled by Artik.

The same issue applied here in terms of voice recognition versus voice authentication. With that said the industry is aware of that problem and a variety of companies are already talking about on how to address that issue. One company joined a panel discussion on smart homes and addressed this exact problem with their software by focusing on voice authentication.

Talking to that company called Knurld was very interesting as many voice authentication solutions require a certain length of words or phrases being spoken before a person can be positively identified. The most common length for this procedure is about 10 to 15 seconds. However, in the smart home world the average length of any command set is about 3 to 4 seconds max which is what Knurld is targeting. Another aspect is voice training of the software to enable any voice authentication which can be quite lengthy where Knurld requires 30 seconds of training. Details on Knurld can be found under http://www.knurld.io

Companies like Google, Amazon and other voice recognition focused companies will tackle this sooner than later as customers’ demands drive innovation. A discussion with an Amazon Echo developer went into the right direction and hopefully find its way to their product enhancement list.

rbac

The discussion was around voice authentication and authorization. The concept of Role Based Access Control (RBAC) is very well known in the IT (not IoT) world but not so much in the voice control world… yet. The use case around this became obvious where the home owner defines certain roles and maps household members to those roles.

As an example the husband and wife have superuser rights while the kids are only allowed to use certain devices mapped to their roles. Guests at home are only allowed e.g. to control lights and nothing else. This is where the future should be going combining voice recognition with voice authentication and then voice authorization.

More to come in part 2 of this IoT World report. Stay tuned.

 

Garage Door

Garage Door

To automate your garage door you will need a simple Z-wave relay and a sensor to determine if the garage door is closed or opened. Depending on your home controller there are many ways to accomplish this but here are two examples.

Vera controller:

(there is more expensive version out there from Evolve called LFM-20 and I have both of them. They both do the same job so why pay more for the same functionality).

You will also need to install a plugin which controls the logic for the garage door. You could program this yourself as the logic is not very complex but why should you reinvent the wheel. The logic has to include things like trigger the garage door and let it run until it is closed and then check the sensor if the garage door is closed or open. It also has to cover the relay function as each garage door opener is different but they all have a certain logic in terms of how long a contact has to be opened or closed to perform certain actions. Just installing the Z-wave devices will NOT work out of the box.

I would also recommend to purchase a project box either at Home Depot or at Amazon to put the Z-wave relay and the wiring inside. The good news is that typically each garage door outlet on the ceiling has 2 power outlets so you can use one to power the garage door opener and one to power the Z-wave relay. The project box below placed on the garage door opener was purchased at Home Depot.

The Tilt sensors are typically battery operated and you can either screw them on the garage door or use Velcro. My battery lasted over 1 year before I had to replace it.

I would also recommend to create some logic in your home automation controller to make proper use of the setup above.

The most common use case is GEO fencing. GEO fencing is the term for location aware reaction of your home automation system.

geo fence In this example you create either one or two virtual fences around your home. The first fence is very close proximity e.g. 100 to 200 feet to capture if you leave your home. The second fence could be a couple of miles.

Most people go with one fence only but others go with a second one to e.g. set the temperature of the home to a more comfortable setting so by the time they get home, the house is nice and cool or warm and cozy.

In this case most people program their garage door to open when they approach their inner fence (or only fence). The opinions differ here because some people don’t like that as they only want to pick something up and they don’t plan to enter the home and in this case they don’t want the garage door to open.

In either case it is up to the individual to decide if GEO fencing is something useful and desirable assuming the person is ok with having location tracking enabled on their cell phone which most people don’t to save battery life.

Another use case is to warn people if the garage door is left open. There are people out there who purchase a camera just to check if the garage door is really closed or not. With the setup above you could program things like “If night and garage door open for more than x minutes then alert”. There are many ways to notify people and many rules you could create and again it depends on the end user but I hope the examples above sparked some ideas.

Happy Automation!
