LYWSD03MMC-z Update on Z2MQTT Causes devices to be unreachable

Configuration Zigbee

I received a notification in HA to update a few of these LYWSD03MMC-z Climate Sensors which I had connected through Z2MQTT. I have done this process several times in the past and never had an issue. After updating 5 devices I stopped receiving data though the displays do change. Not sure how to fix this. Help or thoughts???

Hi. I have the same problem. After the OTA update, all temperature sensors LYWSD03MMC are unavailable. Has anyone managed to fix this problem?

I had this problem with 1 out of 5 sensors that I have and updated to latest version.
I fixed the problem by force removing the device from z2m and repairing it. everything works as expected after that

Thanks. It works. I had to remove the sensor from HA and add it again.
