In case of possibility, can somebody tell me which PIN’s I need to connect? Thanks in advance Geko July 22, 2017 at 11:59 pm #47227 RayKeymaster OSPi already has a rain sensor port, and you can plug your rain sensor into that port. NO or NC can be set in software (Edit Options). Author Posts Viewing 2 posts - 1 through 2 (of 2 total) You must be logged in to reply to this topic.
