Reset accessory

The Reset accessory action resets one or more HomeKit accessories whose configuration may have changed. The accessory behaves as if it’s being set up for the first time, so you need to restore its name, group, room, scene, and automation settings afterward.

This is useful after changing a media player’s device class to tv, linking a battery sensor, or whenever Home Assistant adds support for new HomeKit features to existing entities.

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 reset an accessory from an automation or a script:

  1. Go to Settings > Automations & scenes.
  2. Open an existing automation or script, or select Create to start a new one.
  3. If you’re setting up a new automation, add a trigger in the When section. Scripts don’t need a trigger.
  4. In the Then do section, select Add action.
  5. From the search box, search for and select HomeKit Bridge: Reset accessory.
  6. Select the Entity to reset.
  7. Select Save.

Options in the UI

Entity (Required)

The entity, or entities, to reset.

Good to know

  • After a reset, the accessory behaves as if it’s set up for the first time. You need to restore its name, group, room, scene, and automation settings.

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).
