It looks like Google Assistant can now do sensors! (At least through SmartThings)
Pics or it didn’t happen:
Seems to be fairly rudimentary right now. Can’t do any Routines in the new Google Home App with them. But it’s nice to be able to query the Temp and Close states. Doesn’t appear to know Motion states yet though.
Can’t find anything in the Actions on Google docs though. Maybe something incoming in the very near future?
