I’ve had the same issue with my controller. I can run manual stations just fine from the app, but when I do it from the controller box, the sprinklers won’t stay on. I pick the zone, set the time, and hit enter. The display will go back to the home/auto screen after 20 seconds or so, and at that point the sprinklers turn off. I was sent a replacement unit a couple weeks ago and it does exactly the same thing. I called customer service again today and they did a forced firmware update. The rep was pretty confident this would fix the issue. I will try it tonight.
