What happened?
Since a few days ago, after updating to Zigbee2MQTT version 2.9.2-2, my Zigbee devices stop responding after approximately one day of uptime.
The devices remain visible in Zigbee2MQTT, but commands (on/off, state changes, automations) no longer work properly.
The only temporary workaround is to restart Zigbee2MQTT, which restores normal behavior for another day before the issue happens again.
This problem has become recurrent and impacts the reliability of my home automation setup.
What did you expect to happen?
I expect all Zigbee devices and accessories to remain connected and responsive continuously, as they did before, without requiring a daily restart of Zigbee2MQTT.
How to reproduce it (minimal and precise)
Start Zigbee2MQTT (version 2.9.2-2)
Let the system run normally for several hours / around one day
Zigbee devices progressively stop responding
Restart Zigbee2MQTT
Devices become responsive again
Zigbee2MQTT version
2.9.2-2
Adapter firmware version
Home Assistant OS Core 2026.4.4 Supervisor 2026.04.0 Operating System 17.2
Adapter
Home Assistant Connect ZBT-1
Setup
Home Assistant Core
Running in VMware on Synology NAS
MQTT broker: Mosquitto
Device database.db entry
No response
Debug log
No response
Notes
This issue started recently and seems correlated with the update to 2.9.2-2.
Before that, the Zigbee network was stable and devices remained connected for long periods without interruption.
