Question about command_line

At this moment I have a working Home Assistent on a Raspbery Pi by following the instructions on: https://home-assistant.io/docs/installation/virtualenv/

But I would like to upgrade and use the hass.io image to enable automatic updates etc. However I have a script with the use of command_line platform. What I read from the introduction of hass.io this is not possible anymore or am I wrong?

sensor 1:
  platform: command_line
  name: Persoon aanwezig
  scan_interval: 300
  command: "python3 /home/pi/get-modem-info.py"

Tested it and did not work :slight_smile:
