Deconz Xiaomi Aqara Door/Window Sensor not reachable

I’m having problems getting a stable connection between Homeassistant with a Conbee II and a Xiaomi Aqara Door sensor. Inside de Phoscon App the status of this sensor is Not Reachable. I can remove and add it but a few hours/days later it becomes unreachable again. Does anyone know how to fix this?

Deconz Add-On: 3.5
Hassio: 0.98.3
Phoscon/Conbee II Firmware: 2.05.67 / Firmware 264A0700

This is my latest log:

I had similar problems with door sensors that are fairly far away from the Conbee stick. I resolved this by adding some mains powered Zigbee devices (Tradfri LED drivers in this case) in between.

Or change the Zigbee channel to something which is not interfering with your WiFi.

Hello when you adding powered zigbee device like tradfri, the tradfri it’s connected with the conbee or withe the ikea hub ?

I have Hue lights (connected through Hue hub) about 1m away from the sensor. Hue uses Zigbee too. On channel 20. Conbee II is working on channel 15. Maybe this is causing issues. I’m at work so can’t test it right now.

Hue lights connected to a Hue hub are not working as repeaters for your Conbee network.

With Conbee. You don’t need the IKEA hub if you have a Conbee.

Hmmm I made the assumption that any Zigbee device that is powered could act as a repeater. Even if it’s on another hub. The Conbee however is just 2 meters from the sensor. Conbee is attached with a usb extension cable to raspberry pi. Is the range of the Conbee that bad?

They only act as a reapter for devices in the network they are in.
The range of the Conbee is pretty good in my opinion but a common issue is inteference either by WiFi or another Zigbee network. Take a look at this for some more info.

I had exactly same problem. Changed battery in one of my (brand new) switches 3 days ago, still keeping connection. Dont know how, but it seems to have fixed my problem at least

I changed the Wifi channel to Channel 1 (was channel 6). Hue hub is now on channel 20 and Conbee on 25. I re-added the Aqara sensor to the Conbee and it’s working for now. If I get connection problems again then I will remove the Hue Hub and add the Hue lights to Conbee. So the Hue bulb will become a Zigbee repeater to help the Aqara sensor to connect to the Conbee.
