I am a new owner of Hubitat. I only get the hub yesterday. I am a long time Smartthings user. Home automation becomes a hobby. I did get to the point where I make my own sensor.
I am making an Environment Sensor that would read Temperature, Humidity, pressure and light level of a room.
There are a few similar sensors like what I built. Why make another one? Hubitat speed and local execution complement my goal in making this sensor. My goal is to have Environment sensor that is fast, easy to maintain and expandable.
Here, I have a youtube video that will show the speed of the sensor reporting. Watch how the illuminance value change instantly based on the light shine on it.
The sensor is unique in the sense that it is powered with DC power and backed by optional recharge-able LIPO/Li-ON battery.
Btw, the sensor is also double up as Router/Extender. There are other sensors as well in the module. I mention some of them at Smartthings community here. I just link it so that I do not repeat myself.
DTH for the module.
If you like to get one, here is my Ebay listing. Currently, I keep a few modules available for members who are interested on the modules.
