I am trying to automate my lights dimming when I turn on the TV… So I put this automation together: - id: '1234567890123' alias: TV Dim Living Room Lights trigger: - entity_id: binary_sensor.livingroomtv from: 'off' platform: state to: 'on' condition: - condition: state …

[image] i00: {{ state_attr(‘‘light.living_room’’, ‘‘brightness’’) / 2 }}’ your quotes are not correct: {{ (state_attr('light.living_room', 'brightness')/2)|int }} would do it. Probably need the |int because otherwise you’re feeding a string for brightness…

Dim lights to 50% of their brightness?
