My system isn't working all of the sudden. To the best of my knowledge,it's been running fine for the last few weeks. Then again, I have started to notice some yellowing grass, so I really don't know how long this problem has existed. I tried all of the standard trouble shooting step (power, rain sensor, manual vs. schedule, etc.). I've had this gen1 controller for over two years and this is the 4th time it's stopped working out of the blue. I really would like this taken care of as soon as possible. I've been patient with the product but I'm just fed-up now. It would be nice if the app would actually show what's going on with your system i.e., don't tell me the grass is watering or a schedule has completed if I that's not actually happening. Please help.
