blueprint:
name: Linked Entities

[](https://my.home-assistant.io/redirect/blueprint_import/?blueprint_url=https%3A%2F%2Fraw.githubusercontent.com%2Falexdelprete%2Fha-blueprints%2Fmain%2Fha-blueprint-linked-entities.yaml)
**Linked Entities v1.2** 🔛
This blueprint allows you to easily create/maintain an automation that links the state of multiple entities:
- turn ANY linked entity ON, it will turn ON ALL linked entities.
- turn ANY linked entity OFF, it will turn OFF ALL linked entities.
- set the brightness of any light entity, it will set the same brightness of ALL linked light entities.
- set the color temp of any light entity, it will set the same color temperature of ALL linked light entities.
- set the speed (percentage) of any fan entity, it will set the speed of ALL linked fan entities.
**NOTE**: You can select any entity with an ON/OFF state (switches, lights, etc.), lights with brightness or color temperature attributes, and Fans with speed (percentage) attributes.
My main use-case was for multiple light switches in the house controlling the same light, but I also use it for other things:
- at dawn, when I turn on the external lights (a shelly switch), I also link the pool light mqtt switch.
- when I want to open the external gate, I can use several linked switches in multiple rooms of the house
- when I want to manually turn on/off the irrigation system, I use two switches (internal and external) to activate my RainMachine cycle
I'm sure you'll find many more use-cases. :slight_smile:
**CHANGELOG:**
- 1.2: (2024-01-28 - thanks @phrak / @TimU for the PR)
- Changed the action to a "Choose" building block to support fan, light and future attributes
- Added support for linked fan speeds
- Added support for linked light brightness and light color temperature
- 1.1: (2024-01-09)
- Optimized service call leveraging trigger.id
- Introduced max_exceeded to avoid warnings in log due to possible self-triggering
- Introduced a small delay after the service call to throttle the automation
- 1.0: (2023-12-29)
- First official release
