Tried this one command line, got this response:

curl -s -H "Content-Type: application/json" -H "X-Api-Key: XXXXXXXX" -X POST -d '{ "command":"getPSUState" }' http://XXXXXXXXXXX/api/plugin/psucontrol

<title>500 Internal Server Error</title>

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

The turnPSUOn and turnPSUOff is working however.

@xoniq could you provide the octoprint log files?

[xoniq]

The error in the log:

AttributeError: 'PSUControl' object has no attribute 'isPSUon'

I did install this one:
https://github.com/kantlivelong/OctoPrint-PSUControl/archive/additional_api_commands.zip
So that should be alright.

Ah I see. Doh!

Can you uninstall and reinstall using the URL then try again?

[xoniq]

Will do it as soon as my print is finished. Should be within the hour.

Edit: Lol, just a capital character fault? 🤣

[xoniq]

Success:

{
  "isPSUOn": 1
}

Thank you for the quick support.

[kantlivelong]

@xoniq Thanks for testing 👍

I've made one additional (and hopefully final) commit to return true/false instead of 0/1 for getPSUState to conform with JSON standards.
