Set light power tracked state

Use this action to tell Home Assistant whether a Bond light is actually on or off, without sending any signal to the light. Bond controls many devices over one-way radio, so it cannot always sense their real state. If the tracked power state drifts out of sync with the light, this action corrects it.

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 the tracked light power state 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 area, floor, device, label, or entity you want to control.
  6. From the actions shown for that target, select Set light power tracked state.
  7. Turn Power state on or off to match the light’s actual state.
  8. Select Save.

Options in the UI

Power state

Turn on if the light is actually on, or off if it is actually off.

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 bond.set_light_power_tracked_state. A basic example looks like this:

ActionActions are used in several places in Home Assistant. As part of a script or automation, actions define what is going to happen once a trigger is activated. In scripts, an action is called *sequence*. [Learn more]
action: bond.set_light_power_tracked_state
target:
  entity_id: light.living_room_lights
data:
  power_state: true

This tells Home Assistant that light.living_room_lights is on.

Options in YAML

power_state boolean Required, default: false

Whether the light is actually on (true) or off (false).

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 light entity behind that target.

  • Entity: one specific light entity, such as light.living_room.
  • Device: every light entity that belongs to a device.
  • Area: every light entity in a room or area.
  • Floor: every light entity on a floor.
  • Label: every light 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 updates the tracked state. It does not send a signal to the light, so the light stays exactly as it is.
  • To also correct the tracked brightness, use Set light brightness tracked state.

Tip

You don’t need to edit YAML to use these examples. Copy a YAML snippet from this page, open the automation editor in Home Assistant, and press Ctrl+V (or Cmd+V on Mac). Home Assistant automatically converts the pasted YAML into the visual editor format, whether it’s a full automation, a single trigger, a condition, or an action.

Automation: resync the light state after using the remote

Use this automation when a physical remote tells Home Assistant the light was turned on, so the tracked state matches reality.

  • Trigger: Remote “on” button pressed
  • Action: Set light power tracked state
    • Target: Living room lights
    • Power state: On
