Add hardwire support in the Retro Kit for motion sensors

Also, this would help with Alexa integration, as existing wired motion sensors pulled in from retrofit alarm kit have to be configured as a “window” or “door”. This limits what can be done with routines in Alexa. For example, try to trigger a routine on “when there is no motion for 30 minutes” … Alexa handles this fine if it knows that something is actually a motion sensor, but not so much for doors and windows.
