Hi.
I have a 9V valves and I’m reading to setup OpenSprinkler with them. In my case, my valve is latching, and I think this is the problem to make compatible with OS software. My valve open circuit with a 9V positive pulse (just one pulse, not continue voltage) and close circuit with a 9V negative pulse (reverse polarity to open).
When working with pulses, I need to configure the valve with two tasks, one to open and another to close. Connecting a motor driver board to 2 GPIO pins, I can open and close, because the motor driver generates 9V and -9V depending on 2 GPIO pins.

So, all this talk about latching valve mode, I recommended a not latching valve, but I did not know its existence for 9V operate.

We are currently away till Monday July 21. Orders placed during this time will be shipped on Tuesday July 22. Thank you for your understanding!
