Have barely used HomeKit, so please be gentle.
I am looking to add a wireless motion sensor to a small entryway and log when anyone enters the area. No power there, so needs to be battery-powered and wireless. I am looking for hardware recommendation; and how to set up HomeKit or other app to do the logging (and/or notifications).
I have several of the major hubs, by the way: Aqara, SmartThings, Lutron. And I see Aqara has a motion sensor that looks like just what I need.
Doable?
