I saw the setup that shows wiring a Rachio 3 with the Hunter Rain Clik Rain Sensor. But it only shows the Blue, White and 2 Yellow wires being connected. I have an additional Orange wire on my new Hunter I received in the mail today. The Hunter manual states that the Orange wire is for normally open sensor terminals.
Does I just leave the Orange wire Disconnected? If not where do I connect it on the Rachio 3?
