Issue with zigbee2MQTT and TUYA LCZ030 Temp/Humidity Sensor

Posted: Thursday 17 February 2022 13:00

I've successfully used the "MQTT Auto Discovery Client Gateway with LAN interface" with zigbee2MQTT to add new devices to my Domoticz test setup and it has created devices for the two zigbee devices I have connected. However, everything works except that the Humidity on the LCZ030 is always shown/recorded at 0% on the Domoticz device pane...

Watching the device pane closely it appears to initially update the values for temperature and humidity correctly and then update a second time with no or a zero value for the humidity each time a new status message comes though, it's hard to be sure as it happens so fast, but this does seem the case from the log file. For each status update message the log shows...

2022-02-17 11:31:26.045 zigbeeMQTT: General/Text (Living Room alarm humidity)
2022-02-17 11:31:26.054 zigbeeMQTT: Temp + Humidity/THGN122/123/132, THGR122/228/238/268 (Living Room Temp Humidity)
2022-02-17 11:31:26.062 zigbeeMQTT: Temp + Humidity/THGN122/123/132, THGR122/228/238/268 (Living Room Temp Humidity)
2022-02-17 11:31:26.070 zigbeeMQTT: Lux/Lux (Living Room illuminance lux)
2022-02-17 11:31:26.074 zigbeeMQTT: Lux/Lux (0xcc86ecfffed10c88 illuminance)
2022-02-17 11:31:26.082 zigbeeMQTT: Temp + Humidity/THGN122/123/132, THGR122/228/238/268 (Living Room Temp Humidity)
The status message for the device being processed (which looks good to me) typically looks like this..

Code: Select all

{"alarm_humidity":"off","alarm_humidity_max":90,"alarm_humidity_min":20,"alarm_temperature":"off","alarm_temperature_max":40,"alarm_temperature_min":10,"battery":40,"humidity":54.3,"illuminance":6991,"illuminance_lux":5,"linkquality":218,"temperature":19.7,"voltage":2800}
These are the devices created by the autodiscover hardware for with the LCZ030...

Any help in resolving this issue would be much appreciated :)

Could you also post the 'config' data (JSON payload) of this node ?

gizmocuz, do you have an example for a autodiscovery config json payload for a device like this?

Sorry for late reply, I didn't have reply notifications on by default, I have now.

I wasn't sure exactly what you wanted but I've copied all the MQTT config topic messages into one file for this device below...
