First of all I want thanks tomatpasser for that useful plugin.
I used it for power off and on function with GPIO 3 pin everything work fine. Today I connect I2C display and have to change GPIO pin to another because 3 pin needs to display. Shutdown function works fine like always but now I can't power on RPI with the button. I tried different GPIO but only power off function work and no power on. Any advice how to solve this problem?
