has anyone tried using the amazon smart home group feature? I tried using it, but given i have sonos in the living room and another one in the bathroom of which both are named after their respective rooms, i can't create any smart home groups with the same name, such as "living room". A work around i found was to momentarily rename the sonos speaker something else (but do this ONLY in the alexa app not the sonos app), and then create the home group and then rename the device back to how it is in the sonos app (i.e. just "living room").
I don't know if it is something that alexa needs to fix or what. I feel that alexa should have categories setup to distinguish a speaker name vs a light name vs now their smart home group names. They are all different things. Doesn't matter if you have lights all called "living room" they are lights vs a speaker called "living room".
