When I configured the device, the driver interrogated the hardware and created a child device for each station. You can open and close valve on the child devices with optional delay and duration parameters. I guess Ben Rimmasch wrote the driver.Keymaster. There are two ways to make multiple valves run at the same time. One is to use the ‘master zone’ feature. You can define up to 2 separate master zones, and have every zone associated with one or both of them. This way, when a zone is activates, its associated master zone (s) will also be activated.Have you ever wondered how irrigation control valves work? In this short video, we'll take you on a tour inside a Rain Bird valve to learn about the parts a...The typical coil resistance should be around 30 ohm. If it’s too low (like below 15 ohm), you should consider replacing the solenoid. OpenSprinkler doesn’t have shorted solenoid detection feature yet. In the case of shorted solenoid, the fuse is supposed to blow, but if the fuse doesn’t kick in quickly enough, it might damage the triac.Jul 1, 2013 · I have 180 irrigation heads/solenoids. Solenoid specs are: 24Vac .47A 11.3Va inrush .32A 7.7Va holding Can Opensprinkler *run concurrent up to a limit - i.e. maximum 6 zones at one time based on pump capacity. *require certain zones to run sequentially based on piping limits (could specify as part of the name). OpenSprinkler Pi (OSPi) is an open-source sprinkler / irrigation extension board for Raspberry Pi (RPi). It is based on the design of OpenSprinkler, but its ‘brain’ is an RPi instead of an AVR microcontroller.
