I recently had my yard aerated and power seeded and wanted the seed to get some water everyday. I set a fixed schedule for everyday at noon. Today it started while my daughter was cutting the grass (Sunday) and I was away. I tried to shut it down from my app and nothing I tapped on would allow me to stop it.
What I would like to see is a small red stop sign when watering either on the first screen or the remote popup to make the system stop easily.
