Loosing function of Hue Wall Switch Module

Hi together,
I use ConBee 2 via USB extension cord on a Raspberry Pi 3B with Home Assistant and installed deCONZ add-on.
Connected are a lot of different Hue and Ikea bulbs, Ikea Shortcut buttons and everything works OK (not fine). Most issues are with my Hue Wall Switch Modules. I use 5 of them, linked with ConBee and easily used like “room A”, 2 bulbs, Wall Module switches on / off.
This works - sometimes for a few hours, sometimes a few days. But then - you push the button and - nothing happens. This issue is with all modules sometimes, the other ones are working fine at this time.
I really don’t know what to do. It’s really bad, that the easiest link functionality makes this problems sometimes.
Has anybody an idea, what to do to locate the root cause of this and hopefully solve it?
Thanks in advance for any help.
Regards, Daniel

Hi

Can you share some logs? In #deconz you can find out how.

have you checked for interference. best for me was to have the zigbee channel on 25 and ensure that all 2.4 wifi channels used around me are below channel 9…
