After i first started working with HomeKit, I definitely used geo-occupancy. Nonetheless, what I really wanted was a room to know I used to be in it, and so I started to implement Motion Sensors. I used Hue, as I don't need too many different platforms to manage. Now occupancy sensor are great when you've got an space which has steady movement and not too many entrances. So, why are those two items vital? Continuous movement needs to be obvious. It is a motion detector. Therefore, you want steady motion to know if somebody is in the room. Which suggests in motion sensor light switch cease shifting, then the motion sensor thinks no-one is in the room. This is problematical in areas the place you don't move much, akin to when watching Television. Or the bathroom, when you're having a shower. HomeKit has an attention-grabbing strategy to get round most of the constraints in this space. Essentially, you possibly can flip off your automation after so many minutes, but it surely resets that depend each time the motion detector sense movement. So, you walk right into a room and the lights come on. You may say "Turn off after 10 minutes". If you do not move for 10 minutes, the lights turn off. Nevertheless, in the event you do transfer then the countdown to 10 minutes starts once more.
