LYWSD03MMC - Same Values since 2 Months

[mlinko6]

Dear all,

I'm using 4 LYWSD03MMC Temp and Humidity Meters. 3 are flashed and connected over Bluetooth and one is flashed with Zigbee. Then last one worked fine for a while but the it just "froze" at a certain value:

Temp: 22,65 Humidity: 48.68

The only correct value is the Battery which is changing... Do you have any clues on what I did wrong or what I should do to "revoke" the sensor?

Is it possible for me to flash the Sensor with the bluetooth firmware?

Thank you and kind regards, Rok

Support for Zigbee firmware is in the ZigbeeTLc repository.

Im having the same issue since yesterday.

I deleted one of the thermometer which did work for a very long time because i placed it in another room and i wanted to pair it with another repeater.

After succesfully reconnect to the new repeater it did not read temperature, humidity and battery values. it stays with the values after reconnection.

I tried several reconnects with z2m and also reseted the sensor. The sensor is not working anymore and always showing as offline in z2m. But when I read values manually in z2m it is reporting values from battery, humidity and temperature. I can set it from celsius to farenheit in z2m GUI but i cannot disable the icon smiley and cannot hide display. I also cannot reconfigure the device.

I have read that i have to put lywsd03mmc-z.js in z2m config path and set external konverter in z2m. Some devices now show as lywsd03mmc-z this one not. it is showing as lywsd03mmc in z2m.

z2m gui shows that its seen but it does not report values.

Firmware Date: 20240211 Firmware Version: 3001-0120

Logs show that the device is reporting values: Debug 2024-03-06 07:00:20Received Zigbee message from '0xa4c138140e3a285a', type 'attributeReport', cluster 'msTemperatureMeasurement', data '{"measuredValue":2096}' from endpoint 1 with groupID 0 Info 2024-03-06 07:00:20MQTT publish: topic 'zigbee2mqtt/0xa4c138140e3a285a', payload '{"battery":97,"comfort_humidity_max":null,"comfort_humidity_min":null,"comfort_temperature_max":null,"comfort_temperature_min":null,"enable_display":null,"humidity":38.82,"humidity_calibration":null,"last_seen":"2024-03-06T07:00:20+01:00","linkquality":94,"show_smiley":"HIDE","temperature":20.96,"temperature_calibration":null,"temperature_display_mode":"fahrenheit","update":{"installed_version":-1,"latest_version":-1,"state":null},"update_available":null}' Debug 2024-03-06 07:00:40Received Zigbee message from '0xa4c138140e3a285a', type 'attributeReport', cluster 'msRelativeHumidity', data '{"measuredValue":3888}' from endpoint 1 with groupID 0 Info 2024-03-06 07:00:40MQTT publish: topic 'zigbee2mqtt/0xa4c138140e3a285a', payload '{"battery":97,"comfort_humidity_max":null,"comfort_humidity_min":null,"comfort_temperature_max":null,"comfort_temperature_min":null,"enable_display":null,"humidity":38.88,"humidity_calibration":null,"last_seen":"2024-03-06T07:00:40+01:00","linkquality":91,"show_smiley":"HIDE","temperature":20.96,"temperature_calibration":null,"temperature_display_mode":"fahrenheit","update":{"installed_version":-1,"latest_version":-1,"state":null},"update_available":null}'

but the values do not change and the device is reported as offline.

if I refresh the values in GUI it is reporting values almost immediatly.

EDIT: Found the issue so it is now solved and reporting. Binding in z2m was wrong set. I set it to this values and now it is reporting values
