Shell Command with Input select State

Configuration
1

Hello,

i have an problem with executing a shell command with a state of an input select.
This is my Command:

start_stream: ‘/home/homeassistant/.homeassistant/stream_start.sh {{ states(“input_select.stream_source”) }}’

On the Command line i would start it like: /home/homeassistant/.homeassistant/stream_start.sh “tvchannel”
This works perfectly.
When i change the command in the configuration.yaml into: " /home/homeassistant/.homeassistant/stream_start.sh prosieben" its working.

I followed this Instructions:
https://www.home-assistant.io/integrations/shell_command/

My input select is:

input_select:
stream_source:
name: Streaming-Quelle
options:
- daserste
- zdf
- sat1
- prosieben
- vox
- dmax
- kabel-1
- rtl
- rtl2

Greetings from Germany!

Are you seeing any errors in the log? You might try enabling debug:

logger:
  default: info
  logs:
    homeassistant.components.shell_command: debug

Restart, try the command, and check the full log for details (or look in home-assistant.log.)

Brief Googling would seem to imply you need to add the following “shebang” line at the top of stream_start.sh:

#!/usr/bin/env sh

If that doesn’t work then maybe try one of these:

#!/usr/sh
#!/usr/bash
#!/usr/bin/env bash
