Ah, glad to hear you’ve fixed it. Sorry, there are too many versions that I can’t keep my own head clear about them :). I checked the PCB of 1.3u and you are right: on this version you need to solder a wire from the Rain Sensor pin to A1 — this was left as an option so if you don’t need rain sensor you have one extra analog pin to do something else. Anyways, thanks for figuring it out on your own.
