When most people think about motion detection, they think of the security aspect. While this is an important factor, we are going to explore motion detection for automation and control. In my video about the smart garage door opener, I showed you a robot that turns on my garage light when the garage door opens.
What I didn’t talk about are some of the schedules that automatically turn the garage light off. These are handy for when I forget to turn the lights off manually.
But even with the schedules, if I forget to turn the light off, it can remain on for several hours for no reason. This is where Zwave motion sensors like the GoControl, Linear or EcoLink come in handy.
Today we are going to look at the EchoLink motion detector which uses Passive Infrared also known as PIR. The sensor hangs on your wall and sends status updates to your smart hub. There are only two signals, and those are: motion started, and motion stopped.
Inside the box you will find the motion sensor, a battery, a mounting bracket with screws and double-backed tape, and the instruction manual with text that needs a high-power magnifying glass to read.
The first thing you need to do is open the sensor. If you want to spare your fingernails, use a small screwdriver to open the clip on the top of the sensor. Once it’s open, you will see the slot for the battery.
Over in the Wink App, we’ll click add product, go through all of the warning screens, and press the connect now button. At this point, install the battery in the sensor. After a few seconds, you should get a confirmation that the sensor has been added to your hub.
If you have pets, you can use this jumper to set the sensor to ignore small or large pets. There is also a setting that will monitor for motion every 5 seconds. But, this will run your battery down faster. I am going to use the default setting that will wait 4 minutes after a detection event before it looks again.
Let’s put the sensor back together and mount it in the garage.
Put it in a place that can see a majority of where you will be working.
Now, back in the Wink App,
I am going to set up a robot to automatically turn off the light if there has been no motion for over 5 minutes. == do the setup ==
So on the downside of this sensor, i tried to create a robot to automatically turn the light on. I succeeded in that effort except for one small thing.
I used the feature in the Wink App to only turn on the light between Sunset and Sunrise and it didn’t work. In fairness,
I don’t know if this is the Wink App or the sensor that is having the problems.
I have other Sunset to Sunrise robots that work just fine, so who knows. I need to play with that more.
The distance detection of the sensor seems to work as expected. So no problems there.
All in all, a useful piece of technology that is a happy addition to my smart home setup.
