Version 1.2.41 — Added Zigbee firmware updates for LYWSD03MMC sensors, including direct pvvx updates for LYWSD03MMC-z and a staged migration path for older devbis firmware.
Zigbee firmware updates are now prepared for converted Xiaomi LYWSD03MMC sensors.
Devices already identified as LYWSD03MMC-z can update directly to pvvx ZigbeeTLc 3001-0138.
Older LYWSD03MMC devices using devbis firmware are migrated in two stages: first to devbis 1.1.0 (from 2024), then to pvvx ZigbeeTLc 3001-0138.
The update is started from the Homey device firmware screen.
Use a fresh battery and allow around 20 minutes. Removing and reinserting the battery may be requested to wake the sensor, however I did not perform it and even it’s sleepy device, it start updating quite quickly, so I can confirm similar experience like on Zigbee2MQTT.
The legacy migration route still needs feedback from users with older devices, as my available devices are all LYWSD03MMC-z. Hopefully that would work for you, as I haven’t tested, only updated my 3 pvvx variants, most probably you may need to do maintenance or pairing again after the migration from devbis to pvvx however.
Requirements: Homey firmware v13.2.0+ and Homey Mobile App v9.10.0+.
Update on Homey SHS and Bluetooth - currently you will be unable to add/sync LYWSD02MMC sensor due to the specifics of this sensor and incompatibilities with the Homey Satelitte, hopefully fix will be available within few weeks
