PSUControl automation stopped working

What is the problem?
I've been using the OctoPrint-PSUControl plugin:
To control the power of my printer using terminal commands hooked into my Ikea Trådfri outlet. I even wrote a guide on it: PSU control with Ikea Trådfri and no additional HW

While the PSUControl button still works the automatic shutdown after a print has finished has stopped working.

What did you already try to solve it?
I went through the output in the terminal tab and added the only other GCODE than temperature report M105 that I could find: M117 Set LCD Message to the list of ignored commands but to no avail.

Is there any way to check / monitor what's keeping the PSUControl alive except for the terminal output?

Additional info: I think the issue coincided with me installing OctoDash which requires the following plugins:
