My Rachio 3 arrived via amazon. The box was as bit tattered and the unit was a bit dusty on the inside. I went ahead with the wall mount, wiring and app but I am getting absolutely no lights when plugging in the power adapter. I ruled out a blow fuse and outlets issues by plugging the Rachio power supply into an extension cord which is already powering other tools in my garage. I am suspicious that I have received a faulty unit but I’d hate to uninstall this only to find out it was a bad AC adapter referenced in other posts. Can someone at Rachio help?
