Xiaomi Mijia vs Aqara Window/Door Sensor (Battery Level Reporting)

I can’t comment about the zigbee binding but I am using Zigbee2MQTT which lets you use a CC2531 to turn your Pi into a zigbee hub.

I have this setup talking to all my bulbs(Hue, Ikea and INNR) and my Xiaomi mag sensors and buttons.

There’s a post here that I followed to get it all setup.
