Update zigbee converted thermometers (LYWSD03MMC) to new firmware.

[spitfire]

I have a few LYWSD03MMC thermometers flashed with Zigbee firmware from https://github.com/atc1441/ATC_MiThermometer paired to Zigbee network using ZIgbee2MQTT. Is there a way to update them from Z2M using firmware from this repo? Would that require re-pairing?

Any idea how to use that with Z2M? Or do I need to use the Telink flasher?

These are the files for updating the gygrometer in Z2M via the Zigbee OTA protocol from the devbis version in ZigbeeTLc.

For questions about interacting with Z2M, please refer to Z2M resources and help.

For the thermometers flashed with your Zigbee firmware I can see the updates directly in Z2M. I can't see how I could directly flash the paired devices with Z2M, their docs only seem to mention having an index file to provide additional sources for updating. Since I don't have that, I was trying to unpair one of the thermometers flashed with atc1441's zigbee and trying the telink flasher, but I could not see it in the bluetooth device picker. Is there a way to wirelessly re-flash them?

Create an index file for the firmware you need.

Any actions in Z2M for Zigbee OTA or connecting a new device not included in the list of known devices require the creation of special files and programming skills.
