Hi, I’m also a bit lost here. I have the OpenSprinkler V2.3 DC and 24VAC Gardena valves. Its a new build so I don’t have a 24VAC power supply (but could get one). Do I just connect one of each of the solenoid wires to COM and the other wire to the 1-8 row? I then power the unit with a phone charger to the USB plug, connect the Ethernet cable and good to start watering?
Any help would be appreciated as I have all the bits but still watering the garden every day by hand!
