@adiculiniute Of course commercial controllers from Rain Bird, Orbit, and others are only $90-150 that will do exactly what you are asking about. A dedicated device will always have fewer points of failure. You can build this as others are suggesting but it will take an investment of time and money, not the easiest solution. I love building projects but usually stick to those that have functional benefits I can’t get with inexpensive commercial products. Your priorities may be different of course. Tim
