Custom open-source firmware for the Xiaomi LYWSD03MMC Bluetooth thermometer/hygrometer, plus a web-based Telink OTA flasher and a Python USB-to-UART flashing tool. It replaces the stock firmware to enable custom BLE broadcasts and reflashable updates.
Use cases
- flash custom firmware on Xiaomi LYWSD03MMC thermometer
- unbrick a Telink-based thermometer via USB to UART
- get temperature and humidity readings over BLE for home automation
- reflash stock firmware back onto a Xiaomi sensor
- OTA update Telink TLSR82xx devices from a browser
When to choose
- you own a LYWSD03MMC and want open BLE data without Xiaomi cloud
- you need to recover or unbrick a Telink-based sensor
- you want a browser-based OTA flashing tool for Telink MCUs
When to avoid
- you need non-volatile storage and advanced power management - consider pvvx's fork instead
- your device is not a Telink TLSR82xx-based sensor
- you want a supported, licensed project - this repo has no license
