Domoticz to Mosquitto communication Topic is solved

[Eugene]

HI Guys,

I am new to Zigbee and MQTT. I am trying to make my Zigbee network working with Domoticz (2024.1 build 15838). My setup is zigbee2mqtt -> mosquitto -> domoticz.

The problem is that i do not see any devices appearing in Domoticz when i open the MQTT device in domoticz.

i am attaching my mqtt device config in domoticz, the empty device list and mqtt explorer view

here is what i see in mosquitto when i subscribe to all topics using mosquitto_sub.

First two lines pops up when i restart MQTT device in domotics by clicking update, second two lines appear when i flip the switch on Zigbee device.

online
{"level":"info","message":"MQTT publish: topic 'zigbee2mqtt/power plug ledvance', payload '{\"linkquality\":78,\"state\":\"OFF\",\"update\":{\"installed_version\":2109509,\"latest_version\":33908048,\"state\":\"available\"}}'"}
{"linkquality":78,"state":"OFF","update":{"installed_version":2109509,"latest_version":33908048,"state":"available"}}

Please suggest what next i should be looking at? i feel stuck now.

Thanks in advance

Looks like the problem is in Zigbee2MQTT.
There should be devices listed in mqtt homeassistant folder. So it seems your configuration in Zigbee2MQTT is not correct. Check the logs of Zigbee2MQTT.

Second. The new devices from Zigbee2MQTT will not show in the Domoticz hardware gateway setup button configuration list but in the Domoticz device list, menu Setup- Devices.

Thanks. I do not see anything in Menu -> Setup -> Devices either. Had a look into zigbee2mqtt logs but i do not see anything suspicious there. Here is the log from docker start, i cut the rest of the logs which shows just device state flaps when i was generating messages trying to make them reaching domoticz.

also not sure if it matters here or not - i made a fresh setup of Domoticz, there is nothing changed in its default configuration except added MQTT server which i shared on the screenshot above
