So I used to have this working. It “just worked” before without any unintuitive, complicated setup. But since resetting my phone and setting it up fresh, suddenly I can’t get this to work for some reason.
I’m on Android 9 “Pie”. Installed Google Assistant, that’s all working fine (responds to “Ok google…” commands in and of itself). Under Settings I’ve linked it to SmartThings by logging into my Samsung account. All my sensors appear, I can assign them to rooms, etc. And from the separate Google Home app, from there I can successfully control things fine (such as turning a lamp on/off and adjusting its brightness). So that’s all set up correctly. Google Home is properly linked to SmartThings independent of Google Assistant, and can see and control ST just fine via on-screen controls.
The problem is, Google Assistant seems to not understand voice commands to control the “SmartThings” home stuff. I used to be able to say “(ok google) turn on the living room light” or “make the living room light green” or “what temperature is the living room” and it’d respond correctly. Now when I say those things, it just does a google search on the phrase. Something’s broken and I can’t figure out what, partially because I’m setting this up clean so nothing is weird, and also partially because I clearly remember when I tried this before, it just worked with the simplest of obvious setup. I have no idea what I could be missing this time around. Help?
