I switched all of my Sonos devices at my upstate home this weekend from Alexa to Google Assistant (2x Beam and 2x Sonos One) and everything worked great and controlled all of those as well as my 3x Connect:Amp devices. The Beam CEC control to turn on and off TVs with Google works great!
I attempted to update the Beam and Sonos One at my apartment when I returned to the city and when I run through the process, the Google Assistant app fails to find any devices.
My apartment setup has the same Sonos account with the latest firmware updates, same Google Account (which is configured for two homes) and is on the the same UniFi networking equipment (different SSIDs).
Are there any known limitations with a single Sonos account at multiples homes? There shouldn't be any limitations on the Google side as I have Ecobee thermostats at Google Home locations. The only other difference is that that I don't have any "real" Google products like a Home Mini at my apartment, so I'm wondering if a regular Google device needs to be a home hub to set up non-Google devices.
