I got the hat board, relay board and two sensors. The relays works. But the sensor.. don't know what I'm missing. I connected it to AN0, and I assume the ground is green/yellow. Also tried it on GPIO21. After a while I noticed you can load different presets in HardwareSetting, so I put chose Automationhat 10 (also tried automationhat 10+hygro). After that, I went to Settings and pressed read on AN0. Voltage shows 00.00-00.02v. What am I missing?
