Stop valve

Use this action to stop a valve while it is opening or closing, leaving it at its current position.

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 stop a valve 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 valve you want to stop.
6. From the actions shown for that target, select Stop valve.
7. Select Save.

Options in the UI

This action has no additional options beyond the target.

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 valve.stop_valve. A basic example looks like this:

action: valve.stop_valve
target:
  entity_id: valve.garden_water

This stops valve.garden_water at its current position.

Options in YAML

This action has no additional YAML options beyond the target.

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 valve entity behind that target.

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

• This action only works with valves that support stopping.
• Stopping leaves the valve at its current position, somewhere between fully open and fully closed.
