I have one of these:
store.idevicesinc.com
It has a light on it as well as a plug that can be switched on and off. I dont care about the light, but the plug is connected to a light in my bedroom. I can say to siri "Hey Siri, turn the switch off (or on)" and the light turns off and on. I can also add it to a scene and say Hey Siri good night. But I want to be able to just say turn the light off and have it know which one i mean. What would I need to change for this to be the behavior? Right now when I say the light, it thinks I mean the onboard light on the thing. I am getting 2 more plugs that are just plugs and maybe this avoids the whole issue. But curious.
