Set climate temperature offset

The Set climate temperature offset action calibrates the temperature reading of a Tado climate device. If the device reports a temperature that is consistently higher or lower than the real room temperature, you can apply an offset to correct it.

This is useful when a radiator valve sits close to the radiator and reads warmer than the rest of the room. An automation can keep the offset in sync with a separate, better-placed temperature sensor.

Using this action from the user interface

If you prefer building automations and scripts visually, Home Assistant walks you through this action step by step. You pick what to target, tweak a few options, and save. No YAML knowledge required.

To set a temperature offset from an automation or a script:

1. Go to Settings > Automations & scenes.
2. Open an existing automation or script, or select Create automation > Create new automation.
3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger. They run when something else calls them.
4. In the Then do section, select Add action.
5. From the search box, search for and select Tado: Set climate temperature offset.
6. Under Targets, choose the climate entities to adjust.
7. Enter the Offset.
8. Select Save.

Targets of the action

This action requires a target. The target is the object of the action. You can point the action at a single entityAn entity represents a sensor, actor, or function in Home Assistant. Entities are used to monitor physical properties or to control other entities. An entity is usually part of a device or a service. [Learn more], a device, an area, a floor, or a label, and Home Assistant will run the action on every matching climate entity behind that target.

• Entity: one specific climate entity, such as climate.living_room.
• Device: every climate entity that belongs to a device.
• Area: every climate entity in a room or area.
• Floor: every climate entity on a floor.
• Label: every climate entity that shares a label.

You can also select different target types in one action. For example, you can add a specific entity and an area as targets in the same action to run the action on both of them at once.

Options in the UI

Using this action in YAML

If you work directly in YAML, or you want to know exactly what Home Assistant does under the hood, this section has the technical reference. It lists the field names you use in YAML, their types, and which ones are required.

In YAML, refer to this action as tado.set_climate_temperature_offset. A basic example looks like this:

action: tado.set_climate_temperature_offset
target:
  entity_id: climate.tado
data:
  offset: -1.5

Automation: keep the offset in sync with another sensor

When a better-placed room sensor and the Tado reading drift apart, recalculate the offset so the Tado device reflects the real room temperature.

• Trigger: The room sensor or the Tado temperature changes
• Condition: The two readings differ by more than 0.5°
• Action: Tado: Set climate temperature offset
• Target: Tado
• Offset: Calculated from the difference between the two sensors

alias: "Sync Tado offset with room sensor"
triggers:
  - trigger: state
    entity_id:
      - sensor.temp_sensor_room
      - sensor.tado_temperature

  - condition: template

      {% set tado_temp = states('sensor.tado_temperature') | float(20) %}
      {% set room_temp = states('sensor.temp_sensor_room') | float(20) %}
      {{ (tado_temp - room_temp) | abs > 0.5 }}
actions:
  - action: tado.set_climate_temperature_offset
    target:
      entity_id: climate.tado
    data:

        {% set current_offset = state_attr('climate.tado', 'offset_celsius') %}
        {{ (-(tado_temp - room_temp) + current_offset) | round(1) }}
