Open-source Zigbee 3.0 firmware for the Xiaomi LYWSD03MMC Bluetooth temperature and humidity sensor, written in C for Telink hardware. It converts the stock BLE sensor into a Zigbee device with battery, temperature, and humidity clusters, plus LCD support and OTA updates.
Use cases
- convert Xiaomi LYWSD03MMC sensor to Zigbee
- flash custom firmware to LYWSD03MMC over the air
- integrate temperature and humidity sensor into Zigbee home automation
- update sensor firmware via OTA
- flash firmware via USB-UART to Telink sensor
- replace stock Bluetooth firmware with Zigbee firmware
When to choose
- you want to use LYWSD03MMC sensors with a Zigbee coordinator like Zigbee2MQTT or ZHA
- you prefer Zigbee over Bluetooth for sensor connectivity
- you need OTA firmware updates for your sensors
When to avoid
- you want to keep using Bluetooth/Home Assistant BLE integration
- you have sensor hardware revisions not supported by the firmware
- you are not comfortable flashing firmware with risk of bricking the device
