Set fan speed tracked state

Use this action to tell Home Assistant what speed a Bond fan is actually running at, without sending any signal to the fan. Bond controls many devices over one-way radio, so it cannot always sense their real state. If the tracked speed drifts out of sync with the fan, 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 fan speed 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 fan speed tracked state.
7. Set the Fan speed to the percentage the fan is actually running at.
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 bond.set_fan_speed_tracked_state. A basic example looks like this:

action: bond.set_fan_speed_tracked_state
target:
  entity_id: fan.living_room_fan
data:
  speed: 50

This tells Home Assistant that fan.living_room_fan is running at 50%.

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 fan entity behind that target.

• Entity: one specific fan entity, such as fan.living_room.
• Device: every fan entity that belongs to a device.
• Area: every fan entity in a room or area.
• Floor: every fan entity on a floor.
• Label: every fan 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 fan, so the fan keeps running exactly as it was.
• Use it to resync Home Assistant after the fan was changed with the original remote.

Automation: resync the fan speed after using the remote

Use this automation when a physical remote button tells Home Assistant the fan was set to high, so the tracked speed matches reality.

• Trigger: Remote “high” button pressed
• Action: Set fan speed tracked state
  • Target: Living room fan
  • Fan speed: 100

- alias: "Resync the living room fan speed"
  triggers:
    - trigger: state
      entity_id: sensor.fan_remote_button
      to: "high"
  actions:
    - action: bond.set_fan_speed_tracked_state
      target:
        entity_id: fan.living_room_fan
      data:
        speed: 100
