Note

Building block integration

This switch is a building block integration that cannot be added to your Home Assistant directly but is used and provided by other integrations.

A building block integration differs from the typical integration that connects to a device or service. Instead, other integrations that do integrate a device or service into Home Assistant use this switch building block to provide entities, services, and other functionality that you can use in your automations or dashboards.

If one of your integrations features this building block, this page documents the functionality the switch building block offers.

  • Unavailable: The entity is currently unavailable.
  • Unknown: The state is not yet known.
