Thermostat is off

The Thermostat is off condition passes when a thermostat 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] is currently off. Use it to gate an automation so it only runs when a specific thermostat (or every targeted thermostat) is already inactive.

When you target more than one thermostat, the condition’s behavior option controls how the check combines results. You can require any targeted thermostat to be off, or demand that all of them are.

Using this condition from the user interface

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

To use this condition in an automation:

1. Go to Settings > Automations & scenes.
2. Open an existing automation, or select Create automation > Create new automation.
3. In the And if section, select Add condition.
4. From the search box, search for and select Thermostat is off.
5. Under Targets, select the thermostat entity, an area, a floor, or a label.
6. Under Condition passes if, pick Any or All.
7. Select Save.

Options in the UI

Using this condition 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 condition as climate.is_off. A basic example looks like this:

condition: climate.is_off
target:
  entity_id: climate.bedroom

This passes when the bedroom thermostat is currently off.

Options in YAML

YAML sometimes provides additional options for more complex use cases that are not available through the UI.

Targets of the condition

This condition requires a target. The target is the object that Home Assistant will check. You can point the condition 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 evaluate 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 condition. For example, you can add a specific entity and an area as targets in the same condition to check both of them at once.

Behavior with multiple targets

When you target more than one entity (or select an area, floor, or label that contains several), the Condition passes if option controls how the results combine:

• Any (default): the condition passes if at least one of the targeted entities matches. For example, if you check three smoke sensors and only one of them detects smoke, the condition still passes. This is useful for questions like “is there smoke anywhere in the house?”
• All: the condition passes only when every targeted entity matches. For example, if you check the same three smoke sensors, the condition passes only once all three report cleared. This is useful for “is the entire house safe now?” checks, so your automation does not send an all-clear while one room still has a reading.

Good to know

• Thermostats that are unavailable (unavailable) or have an unknown state (unknown) are skipped and do not count as off. With Any behavior, if all targeted thermostats are unavailable or have an unknown state, the condition fails. With All behavior, if all targeted thermostats are unavailable or have an unknown state, the condition passes.
• To gate an automation on a thermostat being on instead, use Thermostat is on.
• Pair with the Thermostat turned off trigger to react only when a transition to off happens.

Automation: turn on heating when cold and thermostats are off

When the outdoor temperature drops below 10°C during winter, automatically turn on any thermostats that are off and set them to heat mode. This prevents the home from getting too cold if heating was accidentally turned off.

• Trigger: Numeric state: Temperature below 10°C
• Condition: State: Season is winter
• Condition: Thermostat is off
  • Target: All thermostats
  • Condition passes if: Any
• Action: Turn on thermostats and set to heat mode
