I bought 5 second-hand Xiaomi Aqara door/window contact sensors.
I was able to pair all of them in Deconz / Phoscon (Conbee II plugged with USB extension cable) and open/close status changes when I approach or move away the magnet. All good.
I do see the 5 of them in my device list (I renamed one of them for fun)
The problem is their open/close status remains stuck on Open when I play around with the magnet
I searched the internet but couldn’t find anyone describing a similar issue
Any idea what I missed ? Thanks !
