Hey guys!
I want to set up an automation where when a light will be the same brightness as another light.
The reason I want this is that I want 1 light to be brighter, so the plants get more light, but when I press a button it will go back to the same brightness as the other lights.
Currently I got this:
- service: light.turn_on
data_template:
brightness: >
{{ state_attr('sensor.383a0430ce8afb13927a624532308c27_brightness','brightness')|int }}
target:
entity_id: light.kantoor_plafond_001
But this doesn’t do anything. Is it because the deviceID for the other light isn’t right?
