I've got a suncontrol connected to a pi zero via a pi2grove hat. Control of the suncontrol works fine, and I've got an AM2302 temp/humidity sensor working fine on gpio20/21 via the hat.
But trying to get an HC-SR04 ultrasonic distance sensor to work on another set of pins just won't cooperate. I don't think it's the sensor, the trigger pin won't go low. Always stuck high via the pi2grove hat. If I remove the pi2grove hat and wire directly to the zero the sensor works fine.
Tried on other gpio pins and same result.
Any tips to troubleshoot this?
