Description
The problem
I NEED HELP!
My Zigbee network has run like clockwork for over a year but the last couple of months strange errors has come creeping in and after 2025.4.0 it is now PANIC!
ZHA works very randomly. Things become uncontrollable (not unreachable). Been working like crazy last night, after the update, to get some balance again.
Been re-pairing devices that become uncontrollable and that works.... FOR A WHILE. After a restart a whole new set of devices has become uncontrollable and re-pairing them solves the problem until you restart and then a random set of devices becomes uncontrollable again and could be one that I just re-paired.
I can't se any pattern of brands that are more or less likely to have problems.
I get problem with
Aqara thermostats
Tuya light strips
Sonoff motion sensor
Aqara in-wall light switches (no neutral)
Lidl Smartplugs
Lidl Smart buttons
Among others
This morning an update for my SkyConnect became available and I thought that might sove the issues, so I did the update and restarted. Did absolutely nothing.
Same amount of problems and same pattern.
A clue can also be that sometimes a problematic device, after the error message comes up some 30 seconds after the action, starts working and works flawlessly when you turn on/off but after a few minutes that device is uncontrollable again.
Naturally I have searched for colliding wifi networks and the SkyConnect is on an extension cable, well away from anything that can interfer. No issues there and my WiFis are set to fixed channels in the router.
I NEED HELP URGENTLY!
(Wifie is really pissed)
