On specification, it seems this should be able to work with OSPi. It’s driven by 24VAC power, there is a common wire, and individual wires for left, right, up and down. So the four individual wires are equivalent to four zones. To be safe, you should measure the resistance between COM and each of the direction port. The resistance ideally should be more than 20 ohm. The turning speed is 5 degrees per second. Because OpenSprinkler firmware supports water time only down to seconds, you won’t be able to turn it at an accuracy less than 5 degrees.
