Zigbee device keeps disconnecting

Configuration Zigbee
1

Hello

I have problem with Aqara Curtain Driver E1

For some reason, every 1-2 days it disconnects from the Zigbee2mqtt, the signal becomes weaker and the device simply does not respond to commands

To resolve this issue, I have to do factory reset, and then I can connect again. But it’s working only for 2 days.

It’s passive device (works with battery)

Can someone help me

My initial thoughts are Wi-Fi/Zigbee interference issues.

On a good day what sort of LQI do you get with this device ?
How many Zigbee devices do you have in total ?
Which Zigbee channel you are using ?
Which Wi-Fi channel are you using ?
What type of coordinator do you have ?
Where is it plugged in ?
