A motion activated sprinkler could work too. Or buy a motion detector and have it activate plant water sprayers (the kind used for automatic watering of potted plants).

A cheap solenoid will work with garden watering systems and connections. I made an irrigation system that I added to Home Assistant and it’s great.
