Sorry, I must have missed that link when I read your post the first time. I didn’t know these valves exist. Do you know how to control the flow rate — in other words, what’s the electric interface to set the flow rate on these valves? OpenSprinkler can only open or close a valve, I am actually curious how to tell those valves to, say, open 50%, and if that’s the way to open it, how to close it afterwards. It sounds like this would require reversing the voltage polarity which is something that OpenSprinkler can’t do yet (the OpenSprinkler Bee can do so).
