Enclosure plugin button not worked

What is the problem?

I downloaded the enclosure plugin to control the light.
There is an output button at the top, but it does not change to on when i press the button.
I have had the experience of making this a success.
But it doesn't work all of a sudden.
I think it should be switched on and off regardless of the raspberry pie when I press the button on the homepage.

What did you already try to solve it?

I reinstalled the octopi firmware.

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)

안녕하세요 성훈.

Can you please share the Enclosure Plugin settings you made and the connection to the hardware (GPIO).

Output Type : Regular IO
Label : Output 1
IO Number : 4

I connected Raspberry pi GPIO4 pin to relay.

So, referring to the graphic, it's pin #7 on the connector. That's ok.

Can the relay board handle 3,3V control voltage?
The Enclosure Plugin has some advanced options.

In your case, take care that the Use Board Pin # check box is unmarked.

Use Board Pin # check box is marked.
My relay board handle 3.3V control voltage.
Same Relay is being used for PSU CONTROL.
And PSU CONTROL button is worked.
If I give you my address, can you check enclosure plugin button?

If you have the Use Board Pin # box marked, than you have to use 7 as IO Number.
