Loosing zigbee devices randomly

Configuration Zigbee
1

Hi all,

I am running a Sonoff ZBbridge with Tasmota 9.3.1.1 since few months, running perfectly with 11 devices (routers and coordinators).
Since few days, random devices becomes unavailable (device offline) and never come back until I do a re-pairing on each of these devices.

I don’t know if the error is coming from the bridge, from zha or from HA…
Hesitating between updating Tasmota (but why it was working since now?), replacing zbbridge with a usb adapter or burning the whole :joy:

I am running HA version core-2021.11.5
I have an error in the logs regarding zha:

I also activated debug logs on zha and I am getting that… Don’t know if it’s relevant though…

Do you know what I can do in order to debug that?

Thanks a lot!!

I had the same problem shortly after I first set up my Sonoff ZB bridge. The two things that have helped me are:

  1. Add zigbee router devices like lightbulbs, switches, smartplugs, or standalone repeaters.
  2. This may not be true for all sensors, but the Sonoff sensors I got all came with crappy batteries. Replace the batteries with good quality ones.
