I am using a valve with 3 wires: 2 wires to control direction and a common neutral. Powering one wire turns the motor one way, power on the other turns the other way. I am using a Sonoff Dual to control the wires. The current setup is using time based cover; it takes 16 seconds to close or open in my case; the component estimates the position based on run time. Of course there is some drift but that does not really matter; valve is closed every now and then to reset the position.
It would be nice to have a time based valve component as well; I guess that there are more valves out there that work on this principle (more than there are affordable valves with true position feedback).
