Set zone override

Use this action to override the scheduled temperature of a heating zone, for example to warm up the living room earlier than the schedule would. The override can be indefinite, or it can run for a set time after which the zone goes back to following its schedule.

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 override a zone’s setpoint 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. Select what you want to control. Under By target (see Targets), select the heating zone you want to override.
6. From the actions shown for that target, select Set zone override.
7. Set the Setpoint and, optionally, a Duration.
8. Select Save.

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 evohome.set_zone_override. A basic example looks like this:

action: evohome.set_zone_override
target:
  entity_id: climate.lounge_room
data:
  setpoint: 19.5
  duration: "02:00"

This holds the lounge at 19.5 °C for two hours, then lets it return to its schedule.

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.

Good to know

• Leave the duration empty for a permanent override that stays until you change it. Set a duration for a temporary override that reverts on its own.
• A duration of zero is a special case: the override lasts only until the next scheduled setpoint.
