Check the potentiometer connection again. Check continuity of the jumper wires. If everything is OK but still the potentiometer is not working, probably you got a faulty product.

I got it working by setting the switches on the base of the pot from “0,0,0,0” to “1,0,0,0” and then

pot = PiicoDev\_Potentiometer(minimum=0, maximum=1, d=[1,0,0,0]).

Cheers, Ken
