I think I have identified a glitch to be looked into. The speaker groups do not show on on Google home when you operate multiple wifis.
Other apps such as Spotify ideally them fine.
I have a unifi system where my iot devices are separated on as separate WiFi. I can ask Google to play music oe radio on say the work speaker group and it will work fine both nps, this works both on the app and speaker. If I goto the speaker groups on Google home none of them appear or a random 1 may appear. If I sign into the it network all groups appear as normal.
