| description: | | |
| ## Link On/Off/Brightness State of Multiple Devices v2.1.1 | |
| Select multiple entities to link their on/off and brightness state. If any selected entity is turned on or off, or its brightness is adjusted, the other selected entities will be sent a matching on or off command. | |
| You can select any entity, but only entities supported by the `homeassistant.turn_on` or `homeassistant.turn_off` service calls will work. | |
| ### Requirements | |
| * All selected entities MUST suport `homeassistant.turn_on` and `homeassistant.turn_off` or errors will be logged and the blueprint will not work. | |
| * Requires Home Assistant 2024.10.0 or newer. | |
