Can you use HomeKit with apple CarPlay
Why can’t I use Siri in apple CarPlay to turn off my lights or turn them on in my home. But I can use Siri on phone and iwatch to do it? This doesn’t seem correct if not why is this happening?
iPhone XR
Because what you want hasn't been implemented into CarPlay.
