LYWSD03MMC keeps reporting N/A for temperature and humidity #103
Comments
What zigbee coordinator software do you use? What version of firmware did you write? |
Sorry I'm in the Zigbee2mqtt camp. Should make that more clear next time, sorry. I did it in Z2M however: I took this z03mmc.bin file from: https://github.com/devbis/z03mmc/releases/tag/1.0.6
Zigbee2MQTT version |
@EinSchwerd if you get actual numbers for temperature and humidity at the zigbee-level then this seems like a different issue. Maybe yours has something to do with distance towards the device? Move it closer to the actual device it is connected to, or pair it to something else closer? |
I don't get numbers on zigbee-level. I don't get numbers at all. It seems like the device is deadlocked as the server does not receive any messages other than that the thermometer is connected. |
Can you read data from attribute manually? Temperature/measuredValue. |
I put it onto the coordinator antenna and no change. How can I manually read the value from it? It does not change the value displayed on the device itself regularly. It only does a value update when I re-insert the battery. |
Facing same issue, using the firmware from 09.11.2023. The values showed as 'N/A' in zigbee2mqtt. |
Same here! Works for some time and then stops to respond. Taking the battery out for 10 sec and placing it back helps - new values are transmitted for some period (several days) and then the same thing happens. Z2M with external converter. |
Recently there was an OTA update for my sensor, and that fixed it :-)! |
You can configure the reporting time and delta using standard zigbee functionality. What software do you use? |
The configuration is correct. Try upgrade to the latest firmware, use fresh battery and re-join if needed. |
Один и тот-же таймер |
Это не таймер, а колбек на таймер. О каких ограничениях в коде идет речь, если это вызывает такой эффект? Есть ссылка на код реализации таймеров, где это вызывает проблемы? |
А как назначается ID таймера?
ev_on_timer() |
Я не разбирал ваш код, но эффект выходит именно такой – когда значения T и H меняются быстро, передается только одно T или H. |
OK, I thought the OTA helped, but the sensor keeps dropping out. Battery out reset helps for a day or so, then the sensor stops reporting |
Happened to me twice between last week and today. New CR2032 battery and all. Device apparently crashes and keeps stuck on a fixed value of T° and hum%. |
I recently flashed my LYWSD03MMC with z03mmc.bin to transfer it from the custom BLE firmware to Zigbee.
It pairs fine and everything, reports LQI, visually switches to Fahrenheit/Celsius, but the reported temperature and humidity keeps reporting N/A.
I've tried re-pairing them, removing them. Using a different coordinator didn't help as well.
My last resort is reflashing it back to Bluetooth via UART.
Any direction to pinpoint this issue?
The device physically looks like this:
