Vince, I can’t speak for Johan, but I have the same issue, (albeit with Alexa instead of GH). I have had to use a separate Gmail account for each location, and each ST location is connected to a different ST account, (using the corresponding Gmail account for the location), and the Amazon Echoes at that location are logged into the matching Alexa account. You have to do it this way because although ST has a location context, Alexa/GH do not, and neither do most of the cloud connectors for third-party devices. Especially important for me, as I may rent out my vacation home, and I don’t want to take the chance that renters might (accidentally or otherwise) be able to mess with my HVAC at my primary house, for example.
