Shelly Plug S can't be controlled.

I use Shelly Plug S. Octoprint can see its status, but it cannot be controlled.

I am pretty sure it can, because I used a Plug S for testing when creating this plugin. Did you set the Shelly plugin as both switching and sensing plugin in PSUControl? If so, please add debug logging.

I'll attach the debug logs in about an hour, I'm printing right now.

Not necessary, set the Switching Method to Plugin/Shelly and I'm sure it will work.
