I am migrating from C7 to C8 hub, and everything seems to be working fine, except my google integration. I logged into the Google Home Hubitat integration and selected re-connect. It saw both my C7 and C* hubs. Selected C8 and was presented with a list of devices to authorize. Selected Authorize and was presented with a 404 error. Been that way for two days now.
I assume this is an error in the Hubitat integration.
are you using the community integration or the built in one?
I am having the same issue, I have unlinked multiple times but am getting a 404 after i select devices to add to google home.
Did you find a solution?
The built in one. Should
I be using a community
Built one
?
Not yet 
I was able to fix the issue. I cleared data and cache on Google Home app on my phone, unlinked everything on hubitat and GH. Then rebooted my hubitat and was able to add them to my GH.
Tried that. Didn't get the 404 error, I now get a "could not connect to hubitat. Please try again" message.
Concerning the Google Home 404 error: I just found that it works properly on a Mobile Device that has Chrome as the default browser. I must have tried 30 times on my phone which has Firefox only. I switched to a phone which has Chrome only and things worked as they should.
Download the Hubitat app
