Hello,
Please consider fact that I am total noob here as barely learning coding on configuration file
I have raspberry pi attached to 7 inch display works as kiosk. I am able to turn off/ on and control brightness with ssh command prompt. now I need it to be done by home assistant like control brightness with guage.
I have started with below configuration:
sensor:
- platform: command_line
name: TurnOnDisplay
command: "echo 0 | sudo tee /sys/class/backlight/rpi_backlight/bl_power"
- platform: command_line
name: TurnOffDisplay
command: "echo 1 | sudo tee /sys/class/backlight/rpi_backlight/bl_power"
- platform: command_line
name: DisplayBrightness
command: "sudo bash -c 'echo {{ brightness }} >> /sys/class/backlight/rpi_backlight/brightness'"
What is next? how to set brightness, turn ON/OFF and create link it to card on Dashboard/Overview ?
