Use Siri to control Home on Mac
You can use Siri on your Mac to control lights, thermostats and other accessories and scenes. Here are some things you can say to Siri, depending on your accessories, how you’ve named them and the scenes you’ve created:
“Turn off the lights” or “Turn on the lights”
“Dim the lights” and then say “Set brightness to 55 per cent”
“Is the hallway light on?”
“Set the temperature to 20 degrees”
“Close the garage door.”
If you set up rooms, scenes, or more than one home, you can say things like:
“I’m home.” or “I’m leaving.”
“Turn down the kitchen lights”
“Turn on the fan in the office.”
“Set my reading scene.”
“Turn off the lights in the Windermere house.”
