I have an Echo Plus, Echo, Dot, and an Echo Show (all 2nd gen). They are connected via an Orbi mesh network. I am trying to add an Ecobee Plus thermostat to a group named “everywhere” that includes all my Echo devices so I can play music on all. The Echo app doesn’t seem to want to list the thermostat as addable to the group. It has the thermostat in a separate group named “upstairs thermostat”. I could probably add all my Echo devices to that group but I don’t want to have to say, “Alexa, play blank on the upstairs thermostat group” to get music throughout my house. Any suggestions?
