Rain Sensor issue?

I have connected a wired rain sensor to my new Rachio 3. Connected to S1 and vac 24 -. I am see a message in history rain senor active followed by deactivated. Does this mean there is a problem because it has not rained here in over a week and a half. Also it seems like there is a setting in weather intelligence for rain skip, should that be checked since I have a wired sensor?
