Been using the built in Google Home app for some time with no problems. Updated from my C5 to C8. In the Google Home app I had to delete the Hubitat connection and re-enable. Came back up working fine for a couple days. Now it has quit. Deleted again from Google Home. When trying to add it back in I can see my hub, select it, hit Select. After a few seconds I get this message: "The parameter "state" must be set in the query string."
I use Google Home on regular basis and didn't have any problems following the migration. I have seen the parameter state error when users attempt to add unsupported devices. If you didn't authorize new devices, please make sure that all devices previously authorized work as expected.
Apparently the hub lost cloud connection. I had to leave and when I was out I tried accessing using remote admin. My C5 was fine but C8 wouldn’t connect. Not even dashboards. VPN into home, connected to hub ok. Rebooted hub and now is ok. Google reconnected ok.
So why would it lose the cloud connection when nothing else did?
