Cameras to watch Sprinklers to confirm that the water is actually off

After a valve failed to shut off the water after the Wyze Sprinkler turned them on, I wasted 10,000 gallons after 14 hours of sprinkling.
Since the cameras are getting to the point that they could recognize things. Maybe they could recognize if the water doesn’t shut off. The cameras are watching the yard anyway, soooo.
The Wyze sprinkler told the vale to shut off, but it didn’t. I had to do it manually, Unfortunately the watering started in the night and I didn’t notice until later the next day.
