Command_line to curl

Configuration

When posting code to this forum, please be sure to format it properly.

This is the legacy configuration style. It may not be the source of your problem, but I suggest you update to the current standard which would look like this:

command_line:
  - sensor:
      name: Duschwasser Temperatur
      command: 'curl -s http://nodemcu1 | grep -i Duschwasser | cut -c 17-18'
      unit_of_measurement: "…C"

Did you restart HA after adding this to configuration.yaml? When adding a new platform you must restart – a quick reload will not load the new section.

You should check the log files for any errors or issues.
