@Russ Works now, thanks!

@Alfredo-Guzman, you have to switch yourself to the root user before you can edit that file.

This command will switch to root:

sudo su -

@Jack-Bailey, what will steam.py do? Anyway here are some steps you'll need to do. Let me know if you get stuck on any of them.

Create your steam.py file and test it. Install the TRIGGERcmd agent on your Raspberry Pi and test it using one of the built-in commands. Run this to install the background service so it starts when your Raspberry Pi boots:
/usr/share/triggercmdagent/app/src/installdaemon.sh Add your python3 steam.py command to your /root/.TRIGGERcmdData/commands.json file. Something like this:
{"trigger":"steam","command":"python3 \/root\/steam.py","ground":"background","voice":"steam","allowParams": "false"}, Test it using the green Trigger button on the TRIGGERcmd website. Go to ifttt.com and create your Button widget / TRIGGERcmd applet that runs your command. Long-press the IFTTT app icon and select Widgets, and place your button widget on your home screen.

Okay, the command lines you provided work, and I also changed my command word to just "shut" so Alexa can recognize it better. Overall, thanks a lot for helping me, TriggerCMD is definitely a great tool for the raspberry pi.

Ok @js, you could change your commands.json to this:

[ {"trigger":"Monitor","command":"/root/monitor.sh","ground":"background","voice":"Monitor","allowParams": "true"} ]

And put this in your /root/monitor.sh script:

#!/bin/bash if [ "$1" = "on" ] ; then echo Turning it on vcgencmd display_power 1 fi if [ "$1" = "off" ] ; then echo Turning it off vcgencmd display_power 0 fi

And say this to Alexa or Google Assistant:

ask TRIGGERcmd to run monitor with parameter on

Or use the TRIGGERcmd Smart Home Alexa skill or the SmartThings integration with Google Assistant, and say this:

turn on monitor
