This device uses a Tasmota incompatible module which needs to be replaced with an ESP. Besides the module, this process will require a heat gun, soldering tools and moderate soldering skill.

  • Weblog 4 #enable weblog output
  • TuyaMcu 99,1 # disables the default relay on DP iDd
  • SetOption137 1 #disables MQTT forwarding of HeartbeatInfos between TuyaMCU and ESP
  • TuyaMcu 77,2 #Mapping of the DPid 2 to the Co2 sensor value Tasmota
  • TuyaMcu 71,18 #Mapping the DPid 18 to the Tasmota temperature value
  • TuyaMcu 73,19 #Mapping the DPid 2 to the Tasmota humidity sensor value
  • TempRes 0 #The sensor sends integer temperatures, therefore without decimal places
  • HumRes 0 #The sensor sends whole numbers of air humidity, therefore without decimal places

DPid 21 is not used, it is a second humidity sensor based on temperature sensor.
