I don’t know, this seems like a pretty basic feature that I would expect all the mainstream smart home ecosystems to support. Do they not? Is it possible with Alexa/Google Home/ etc. for anyone to say “turn off all the lights in the house” into any smart speaker? I’d honestly expect the defaults to only allow commands to apply to the devices in the same room/group as the smart speaker.
Alexa devices know what room they're in, so if I say "turn off the lights" in the kitchen, the kitchen lights turn off. But if I say "turn off the living room lights" in the kitchen, the living room lights turn off.
(If I have to physically move to a different room to send a voice command about that room I lose a ton of convenience, and the whole point of home automation is convenience!)
