Here is a simple piston that is paired with IFTTT to respond to either Amazon’s Alexa or Google Assistant. Pretty much you need to setup an IFTTT applet to accept your desired voice command from Alexa or Google Assistant and then you can use that to trigger the ArmAway or ArmStay modes of the ADT Security System. Before anyone asks… yes you could setup the system to disarm by a voice command but I highly recommend against it…
Anyways… simple piston code attached. Enjoy!
