I couldn’t find a similar problem, if this has already been discussed, please provide a link.
The problem started not long ago, 2-3 months ago. At random times, one or more end Zigby devices begin to work incorrectly, or rather, they lose remote control (switching), although network availability remains. For example, a switch, when physically pressed, the actions are described in the HA log, but the slider does not turn off remotely, either in the broker or in zigbee2mqtt. The only solution that helps is to restart the zigbee2mqtt add-on, but it may take quite some time before a problem with the device is detected. Please help me figure it out. Today I changed the wifi and zigbee channels, it didn’t help.
