Tuya climate more flexible (current_temperature_datapoint more flexible)

[diogopms]

Describe the problem you have/What new integration you would like

Tuya thermostats with internal temperature sensors require calibration to show the right temperature. Currently, it's not possible to use offset any value because it's connected to current_temperature_datapoint and not to the temperature sensor itself.

Please describe your use case for this integration and alternatives you've tried:

# Not OK - Temperature: 20ºC
climate:
  - platform: tuya
    name: "Thermostat"
    icon: mdi:heating-coil
    switch_datapoint: 1
    target_temperature_datapoint: 2
    current_temperature_datapoint: 3
    temperature_multiplier: 0.5
    eco_datapoint: 5
    eco_temperature: 16 °C
    visual:
      min_temperature: 10 °C
      max_temperature: 30 °C
      temperature_step: 0.5 °C

# OK - Temperature: 18ºC
sensor:
  - platform: tuya
    name: "Temperature"
    device_class: "temperature"
    sensor_datapoint: 3
    unit_of_measurement: "°C"
    accuracy_decimals: 1
    filters:
      - multiply: 0.5
      - offset: -3 # Because of the offset

Hello,

make it simple: filters:

• lambda: return x / 2 + 3;

If you can find a datapoint to set the offset, then sure. But there's no point in adjusting it on the esphome side. All the control is inside the Tuya MCU.

If you want to calibrate internal sensor, then You need to use device functionality, like:

But check Documentation from your vendor, can be different. Ed
