Hi!
Yesterday I moved over from my old Pi3 for my home assistant server to Home Assistant Green.
I did a recovery from a backup that I took from my Pi3 and Everything is working except for publishing commands through Zigbee2MQTT.
I do however get payloads back from the zigbee device that I have on the network so something is working.
This is the error I get from the Zigbee2MQTT log when I try to run an automation:
[2026-04-20 11:08:10] error: z2m: Publish 'set' 'state' to 'Bevattning - Murgröna' failed: 'Error: ZCL command 0xb43a31fffe67c0e0/1 genOnOff.on({}, {"timeout":10000,"disableResponse":false,"disableRecovery":false,"disableDefaultResponse":false,"direction":0,"reservedBits":0,"writeUndiv":false}) failed (Delivery failed for '7873'.)'
I get the exact same error in the log when I try to start the irrigation system directly from Zigbee2MQTT interface.
Here is an exemple from the log when I receive a payload from the device:
[2026-04-20 10:56:07] info: z2m:mqtt: MQTT publish: topic 'zigbee2mqtt/Bevattning - Murgröna', payload '{"auto_close_when_water_shortage":"DISABLE","battery":79,"current_device_status":"water_shortage","cyclic_quantitative_irrigation":{"current_count":0,"irrigation_capacity":0,"irrigation_interval":0,"total_number":0},"cyclic_timed_irrigation":{"current_count":1,"irrigation_duration":50,"irrigation_interval":1,"total_number":1},"flow":0,"linkquality":180,"state":"OFF","update":{"installed_version":-1,"latest_version":-1,"state":null}}'
Any idea where I have gone wrong?
Thanks in advance!
