Setup was easy just make sure you plug your common wire (mine was black) into one of the "C" ports and then youre done.
Im going to use the watering schedule that the app suggests based on using my local weather station, so well see how that works. Love the convenience and control it offers. I didnt have a rain sensor on our sprinkler system so not having so the sprinklers going when it rains is big.
