Pairing InstructionsReinsert the battery and/or short the RESET and GND contacts above the battery for 3 seconds.
This Bluetooth sensor can be converted to a Zigbee one with just a webpage and a device with Bluetooth. Open the web flasher and follow the procedure in video.
- make sure the Xiaomi sensor is close to the Bluetooth radio
- use a full battery, if its lower than 40% flashing could fail and brick the device
- if the sensor disconnects mid flash (for me it was around 50%) try installing the BLE 4.5 firmware first then do the Zigbee conversion
If the OTA fails or you want to revert back to Bluetooth firmware you need to flash it using a serial to USB adapter. Wire the device like this:
“Write to Flash” and wait for the process to complete. If you have issues run “Erase All Flash” first.
