Haha I'm going to make a clean post about it when I have it working 100% in practice but I've proved it out to work.
Basically taking advantage of SmartThings updated Alexa skill that allows motion sensors to be used as triggers of routines. Also using Other Hub SmartThings Integration:
Basically the flow will be:
Life360 Presence home-> Hubitat rule switches custom motion sensor with switch capability (reset somehow) -> Other SmartThings Hub Integration changes mirrored motion sensor to activated -> Alexa fires pre-configured routine -> routine has Alexa says function.
That simple! lol
