You haven’t used the beta

I tried "turn off the lights in [room a] and [room b]" in the new Siri app and rather than Siri saying they can't do compound commands they just turned off the lights in one of the two rooms listed.

So, progress?

Any agent with the Home Assistant MCP hooked up can do it fine.

Now playing "Turn Off the Lights" by Teddy Pendergrass on Apple Music.
