Aqara Door and Window Sensor

Description

All doors in my home include an Aqara Door and Window Sensor. Eventually I will hit the windows too, but the doors were most important initially. I am using these mostly to automate lights, but also to send notifications if an exterior door is open for too long, or when heading to bed for the night. I have these connected to Home Assistant via the SkyConnect USB stick, then sent to Apple HomeKit. The price is right and they have been reliable for two years now, with no battery changes!
