I can't answer your question. But I think this part of HomeKit (assuming this is HomeKit) is yet something else that is fundamentally screwed by those Muppets at Apple. Very randomly when I put on my Apple Watch in the morning, all of my cameras start recording and I get notification saying that everyone has left home. I then have to restart my iPhone for them to go back to "at home" mode.
It's like Apple is going out of its way to make everything completely and utterly 100% unreliable.
