Hey,
I want to create an automation, which turns on the Monitor attached to the RaspberryPi running Hass and shows a webpage.
The Switch turning the Monitor on and off works and also the corresponding automation, excpet one little part.
- service: shell_command.start_chromium_poster
The command is defined as follows:
shell_command:
start_chromium: 'chromium-browser --kiosk --incognito "http://localhost:8123/local/test.html"'
If I execute that command right in the terminal (not ssh) everything works.
Can someone tell me, what am I doing wrong?

Solved it!
I just needed to add something:
start_chromium: 'DISPLAY=":0.0" chromium-browser --kiosk --incognito "http://localhost:8123/local/test.html"'

DISPLAY=“:0.0”
I cannot get this to work, my home assistant is running on a Debian Pi in a virtual environment.
pi@raspberrypi:~ $ sudo -u homeassistant -H -s
homeassistant@raspberrypi:/home/pi $ source /srv/homeassistant/bin/activate
(homeassistant) homeassistant@raspberrypi:/home/pi $ chromium-browser

(chromium-browser:1039): Gtk-WARNING **: cannot open display:
Trying “DISPLAY=”:0.0" chromium-browser" results in " Gtk-WARNING **: cannot open display: :0.0"
I found a fix, as the user logged into the pi locally (and connected to a display via HDMI) is “pi” and hass is running as a non-graphical user, you have to state the user to run the program as, using " sudo -u pi":
pi@raspberrypi:~ $ sudo -u homeassistant -H -s
