@petrockblog Hello! Thank you for the fast answer. Unfortunately I've already tested those scenarios and the hat is not working. I don't have an order number because I bought the board from another seller. I just wanted to know if I'm doing something wrong or not. I'll contact them about this.

Thank you again!

Can you show an image of your hardware setup?
Instead of using a switch you could try and only short-circuit the switch pins on the PowerBlock with, e.g., a jumper. That should turn in the Pi.
Does that change anything?
