I want to share with the community about a project that I am working on. But, first, I want to make sure give credits to a couple members here who helped me tremendously. I want to thank @alwas for his relentless advocacy to make the arrival sensor available in ST. One of his effort is to introduce me to @Mariano_Colmenarejo who wrote the edge driver for the sensor. Without his effort, the following demo would not be possible.
As a background, I had a couple ST arrival sensor from back in the day. I used them in my car to track my car come and go. We got an additional car and need a new sensor. I found that they are discontinued and very hard to find a used one.
I thought it would be fun to make one myself. I started to make one with the same functionality with the original ST arrival sensor with the following improvement. I use a recharge-able battery which will be filled up during a drive. I also use a powerful Zigbee module with an external module.
I added motion sensor and vibration sensor to help securing my car while it is parked outside the house.
Here is a short demo how it work.
Here is one of the thing that I do with the sensor in automating my garage door. Warning: if you have amazon echo nearby, you may want to turn off the mic.
Here is how the sensor look like.
The edge driver is available from the Maestro himself, @Mariano_Colmenarejo. The edge driver will allow the driver to run local in your hub. It will make the sensor run fast. If you need to make modification or learn how to write Edge driver, @Mariano_Colmenarejo will share the code on his github. The detail should be coming soon. I am looking forward to this as well. In the meantime, here is his channel to install the driver.
I made a handful of boards. If you are interested on testing it out please feel free to PM me. There will be reasonable cost for the sensor because I have to recover the component cost. I am just a hobbyist.
Update: some screenshot
Update: Github repository for the arrival sensor edge driver
Update: In case your sensor only update some attributes partially, please take a note on this.
Update: STL files for 3D printed cases for the sensor
Update: I just want to make sure that I mentioned that the sensor is DIY kit with component is soldered. A case may be needed to complete and ensure a nice and safe use.
Update: Important update regarding battery protection issue.
