Tuya Climate

The tuya climate platform creates a climate device from a tuya component.

The Tuya fan requires a Tuya MCU to be configured.

[22:03:11][C][tuya:023]: Tuya:
[22:03:11][C][tuya:032]:   Datapoint 1: switch (value: ON)
[22:03:11][C][tuya:032]:   Datapoint 2: switch (value: OFF)
[22:03:11][C][tuya:034]:   Datapoint 3: int value (value: 20)
[22:03:11][C][tuya:034]:   Datapoint 4: int value (value: 19)
[22:03:11][C][tuya:034]:   Datapoint 5: int value (value: 0)
[22:03:11][C][tuya:036]:   Datapoint 7: enum (value: 1)
[22:03:11][C][tuya:046]:   Product: '{"p":"ynjanlglr4qa6dxf","v":"1.0.0","m":0}'

On this controller, the data points are:

  • 1 represents the climate on/off state.

  • 2 represents the child lock switch. (use the Tuya Switch component to control this)

  • 3 represents the target temperature.

  • 4 represents the current temperature.

  • 5 represents the timer but is not yet available to be used in ESPHome.

  • 7 represents the eco mode switch.

Based on this, you can create the climate device as follows:

climate:
  - platform: tuya
    name: "My Climate Device"
    switch_datapoint: 1
    target_temperature_datapoint: 3
    current_temperature_datapoint: 4
    eco_datapoint: 7
    eco_temperature: 20 °C

Configuration variables:

  • id (Optional, ID): Manually specify the ID used for code generation.

  • name (Required, string): The name of the climate device.

  • supports_heat (Optional, boolean): Specifies if the device has a heating mode. Defaults to true.

  • supports_cool (Optional, boolean): Specifies if the device has a cooling mode. Defaults to false.

  • switch_datapoint (Required, int): The datapoint id number of the climate switch (device on/off).

  • active_state_datapoint (Optional, int): The datapoint id number of the active state - see below.

  • active_state_heating_value (Optional, int): The active state datapoint value the device reports when heating. Defaults to 1 - see below.

  • active_state_cooling_value (Optional, int): The active state datapoint value the device reports when cooling - see below.

  • heating_state_pin (Optional, Pin): The input pin indicating that the device is heating - see below. Only used if active_state_datapoint is not configured.

  • cooling_state_pin (Optional, Pin): The input pin indicating that the device is cooling - see below. Only used if active_state_datapoint is not configured.

  • target_temperature_datapoint (Required, int): The datapoint id number of the target temperature.

  • current_temperature_datapoint (Required, int): The datapoint id number of the current temperature.

  • temperature_multiplier (Optional, float): A multiplier to modify the incoming and outgoing temperature values - see below.

  • eco_datapoint (Optional, int): The datapoint id number of the eco mode state.

  • eco_temperature (Optional, float): The target temperature the controller uses while the eco mode is active.

If the device has different multipliers for current and target temperatures, temperature_multiplier can be replaced with both of:

  • current_temperature_multiplier (Optional, float): A multiplier to modify the current temperature value.

  • target_temperature_multiplier (Optional, float): A multiplier to modify the target temperature value.

  • All other options from Climate.

Active state detection

Some Tuya climate devices report the active state (idle/heating/cooling) via a tuya data point. In this case, you can use the active_state_datapoint variable together with active_state_heating_value and active_state_cooling_value.

If your device does not make a data point available for this, it is possible to modify the hardware so that the relay outputs can be read by the ESP. Please refer to this discussion <https://github.com/klausahrenberg/WThermostatBeca/issues/17> for more details on the required modifications. You can then use the heating_state_pin and/or cooling_state_pin configuration variables to detect the current state.

If none of the above variables are set, the current state is inferred from the difference between the current and target temperatures. If supports_heat is True and the current temperature is more than 1 °C below the target temperature, the device is expected to be heating. If supports_cool is True and the current temperature is more than 1 °C above the target temperature, the device is expected to be cooling.

Temperature multiplier

Some Tuya climate devices report the temperature with a multiplied factor. This is because the MCU only utlizes integers for data reporting and to get a .5 temperature you need to divide by 2 on the ESPHome side.
