I can check it later on, if it needs. The other two works, so it's fine for me! One other question though.. I'm looking at the AutoWatering setting. "Sensor threshold" uses volt, and has min 2.0 and max 4.0. What unit/numbers am I supposed to use there? Does it go by the same moisture numbers in the hardwaresetting? which is % for me. And what would be a good starting point? I assume I'll use 0-100% moisture.. and could use like 40-50% - 80%?

Oh, and another thing. Right now I'm using usb c for the raspberry, and a power adaptor for the valves. To use the power adapter only (through a step down), I just connect it to pwr_conn, right?

GPIO18 works. So I moved the other one to GPIO14, and now that gives reading as well. Maybe the 24 (and 21) pins are bad, somewhere, or there's some software related things I missed.

@hydrosys4 Yes so I have it on GPIO21, and I get ”SlowWire reading error”. Blue on gnd. Not sure if I am missing something. Heres a photo of my table. My addition at the bottom:
