Get pin status

[abonec]

I write a program to turn on my computer via telegram bot here:

I use hwio to turn a relay on and off to short the power button. Now, this part of the program is dead simple and no way to going wrong. But while developing I faced with situations where relay turned on but because of my fault, it stays in this state. It is bad for PC.

Is there some way to check pin state? I want to run a watchdog which every second will check this pin and turn it off if it is turned on.
