ON/Toggle after offline

[DetlefR]

Hello,

I use Xiaomi WXCJKG12LM and WXCJKG11LM. When the switches not used for some days they are going offline. This is normal and not the problem. But when I use an "offline" switch, other zigbee relays and bulbs switched on (or toggle?).
I cannot see any event in mqtt excepted the message from the used switch.

I'm not sure since when this behavior occurs. But in the past it wasn't there.
Do anyone know what can I do against.
