PSU Control automatic Power on at boot?

Hi everybody !
I need some information about the PSU plugin.
There ist an option to atomatic switch it on at power on /boot .
If I boot the system it will not switch the switch on. If I click it manually everything is doing fine as expected.

I tried so many settings but I'm not able to get it working .
I expected, to switch on the power supply, the raspi will boot octoprint and then it will switch on the relay and start the printer.

Any suggestions ?

I'm having the same problem! It boots up with the relay turned off. very frustrating

after more experimenting, it seem that the 'invert' settings for the switching and sensing GPIO need to be carefully chosen however whenever I have one invert selected and the other not selected, the toggle switch doesn't actually work. Unfortunately this is the combination I need to make my set-up work correctly.

I tried these settings any many other combinations as well and this thing will always boot up with disabled relais. I can switch it still manually and then its doing what I expect, but thats not what I wanted. So I decided to remove the plugin and removed the relais. I power the thing up (printer AND the pi) and then I do the do, and after all I shut it down using the webinterface, or I use the GPIO-Shutdown plugin and use a small reset switch. So after the work, I hit the button, the pi shut down and after that I switch off the printer ..
Thats my "workaround" for the next time.

yeah after all day today messing with this I think I am about there as well!
I've tried additional transistors and, pull up and down on various pins with loads of setting combinations but no joy
