There is a plugin called ‘relay board’. Enable that, and then open sprinkler simply turns the IO pins on and off. Each IO pin can be used with each relay on the board, so that’s your sprinkler control (I’m assuming you know how a relay works, and how a relay can be used to connect the 12v power supply that drives each valve).
