Experimental firmware for devices on the TLSR825x chip operating simultaneously in Zigbee 3 and Bluetooth LE.
It is not recommended to use experimental versions for those who do not have the ability to reprogram the device using wired connections!
Currently supported devices: LYWSD03MMC, CGDK2, MHO-C122, MHO-C401N, TS0201_TZ3000, TH03Z
In developing: MHO-C401(old), MJWSD05MMC, CGG1-M, TS0202_TZ3000
- Zigbee OTA
- BLE OTA
- BLE advertising BTHome v2
- Screen display configuration
- Setting offsets sensors
Average consumption for Xiaomi LYWSD03MMC B1.4 - 18 µA
- Warning: Not use BLE OTA TelinkMiFlasher for this version! In the current experimental version, BLE OTA is not yet stable. You may have to use TelinkOTA.html several times.
Action of the button (or contact "reset" to "gnd" for LYWSD03MMC):
- Short press - send temperature, humidity and battery data.
- Hold for 2 seconds - Switches temperature between Celsius and Fahrenheit. The change will immediately appear on the screen.
- Hold for 7 seconds - reset the binding and restart. The screen will briefly display “---” (for devices using a screen with fast refresh capabilities, not E-Ink). After restarting, the thermometer will wait forever for registration. Jerking the battery won't change anything.
ZHA patch for more precision display of data for all Zigbee devices.
A solid "BT" icon indicates a connection loss or the thermometer is not registered with the Zigbee network.
The flashing "BT" icon is called by the "identify" command.
ZHA: Switch temperature between Celsius and Fahrenheit, Show smiley, Comfort parameters
ZHA: Setting offsets for temperature and humidity
RelativeHumidity: min/max/change - 30/180/50
TemperatureMeasurement: min/max/change - 30/180/10
If the measured values by the sensor change rapidly:
For BLE, the transmission step of all measured values is always 10 seconds. The transmission is duplicated 2 times in 5 second increments.
Zigbee transmission: 
BLE transmission: 
For those not afraid to experiment:
- The firmware is carried out from the BLE version by downloading a *.zigbee or *.bin file in TelinkMiFlasher.html. In the file name input field, paste
https://github.com/pvvx/BZdevice/raw/master/bin/1141-020a-02053001-Z03MMC.zigbee(for LYWSD03MMC) - For BLE OTA, when this version is already working, TelinkOTA.html is used.
Before flashing the firmware, check the compliance of the “Manufacturer Code” and “Image Type” between the OTA file and those issued by the Zigbee device.
