How to run commands from Home Assistant

[blizzrdof77]

@russ Thanks for this, by the way!

For anyone else using TriggerCMD with Home Assistant, I wrote this helper script with a rest_command that I have found very useful for running commands with parameters (or without parameters).

Just be sure to change "ADD.YOUR.TRIGGERCMD.TOKEN.HERE" to your token.

The Script:

## -- RUN TRIGGERCMD REST COMMAND
script:
  run_triggercmd_rest_command:
    alias: Run TriggerCMD REST Command
    description: Execute a RESTful command with params and a device using triggercmd.
    icon: mdi:apple-keyboard-command
    variables:
      params: ''
      token: 'ADD.YOUR.TRIGGERCMD.TOKEN.HERE'
    fields:
      trigger:
        description: The name of the trigger
        example: Exit Windows Program
        required: true
      computer:
        description: The name of the computer as shown in your computer list on triggercmd.com.
        example: My Computer Name
        required: true
      params:
        description: Optional args string to pass with the trigger, using a space for multiple params [optional].
        example: ''
        required: false
    sequence:
    - service: rest_command.tcmd_run_command
      data:
        trigger: "{{ trigger }}"
        computer: "{{ computer }}"
        params: "{{ params }}"
        token: "{{ token }}"

The Rest Command

## -- RUN TRIGGERCMD COMMAND
rest_command:
  tcmd_run_command:
    url: 'https://www.triggercmd.com/api/run/triggerSave'
    method: POST
    content_type: 'application/x-www-form-urlencoded'
    payload: 'trigger={{trigger|replace(" ","%20")}}&computer={{computer|replace(" ","-")}}&params=+{{params}}&token={{token}}'

Example Usage

service: script.run_triggercmd_rest_command
data:
  trigger: This Is The Trigger Name                 # Literally the name of the command
  computer: My Computer                             # (will render as 'My-Computer')
  params: '--female "Shutdown request confirmed"'   # This has 3 params

@blizzrdof77 @Russ I am new to HA and trying to get this working but not sure if my issue is related to possible syntax changes since 2021. Does this format still apply? Thanks.

[Russ]

@AZRushFan, yes, I just tried it. It worked for me with this text at the end of my configuration.yaml:

rest_command:
  triggercmd_calculator:
    url: 'https://www.triggercmd.com/api/run/triggerSave'
    method: "post"
    content_type: "application/x-www-form-urlencoded"
    payload: "trigger=calculator&computer=russfam&token=(my token)"

That said, would it help if I built an official Home Assistant integration?

EDIT 9/15/24: The official TRIGGERcmd integration will be available in next Home Assistant version (2024.10). It's due to be released on 10/2/2024. Please try using it instead of the "RESTful Command" method described above.

@Russ I am testing out the HA integration for TRIGGERcmd and curious on the best practice when using the switch functionality when triggering a script. In my instance it is a single instance AutoHotkey script so by definition there is no "off"; however, it doesn't trigger the next time I try to run it as the switch is still in the on position in HA. What do you suggest? Thank you.

[Russ]

@AZRushFan, in my experience I've been able to trigger the ON switch many times in a row even though the HA virtual switch status is ON. Are you saying you can't trigger the ON command if the switch is already ON?

[AZRushFan]

@Russ well as you mentioned it does indeed. I think I had another issue that was preventing the trigger in HA. Thank you.

Hello guys,

Does Home Assistant integration run commands locally?
Is it still limited to 1 command per minute in the free tier?

Thanks

[Russ]

@rdaraujo, yes, it runs the commands locally without the 1 command per minute limit even if you're not subscribed.

@Russ, thank you for HA integration, would be really great if it also showed "offline" PC's entities as "unavailable".

It would be also very helpful for automations.

[Russ]

@Andru, thanks for the idea. I'll look into it.
