Run URL as action isn't working

I’m trying to create an automation to open a specific URL (which triggers another device).
But I can’t get it working, it keeps sending me the “Unable to determine action @ data[0]” error.

Does anyone know what I did wrong?

You don’t configure the rest command in the automation.

You put it in your configuration.yaml file then call that command from your automation.

e.g.

configuration.yaml file:

rest_command:
  cinema_adaptive_drc_on:
    url: "http://10.1.1.17/YamahaExtendedControl/v1/main/setAdaptiveDrc?enable=true"

  cinema_adaptive_drc_off:
    url: "http://10.1.1.17/YamahaExtendedControl/v1/main/setAdaptiveDrc?enable=false"

  cinema_adaptive_dsp_on:
    url: "http://10.1.1.17/YamahaExtendedControl/v1/main/setAdaptiveDspLevel?enable=true"

  cinema_adaptive_dsp_off:
    url: "http://10.1.1.17/YamahaExtendedControl/v1/main/setAdaptiveDspLevel?enable=false"

Automation:

action:
  - service: rest_command.cinema_adaptive_drc_on

Note: you have to restart home assistant after creating your rest command.

It works!
Thanks!
