Using Contact and Motion Sensors to Trigger Alexa Routines (DTH in post 97) (Official Amazon Feature)

Devices & Integrations
97

I combined two device handlers into one, so that the device can be triggered like a switch (I used it to turn the switch on when I arrive home, and off when I leave), but is also recognized in alexa as a contact sensor so that it can trigger an alexa routine. I only put this together as a proof of concept, so the code can probably be cleaned up, but it appears to be working.

The two device handlers I combined were the simulated switch:


and joshualyon’s simulated contact sensor:
