Just info :
Latest LYWSD03MMC are shipped with firmware 2.1.1_0159, which requires MI Token Extractor and special modified firmware, so that you can flash later on ATC BLE or Zigbee firmware.
As I just converted one device, some tips :
- if process fails, keep repeating (ensure removing battery, closing and opening browser page)
- seems currently the best Zigbee firmware is LYWSD03MMC-z - installed via Telink Flasher v10.1 - version 3001-0127
