I looked through he forums but I still have a tough time finding a recommendation for a flow meter that would work well with OpenSprinkler.
Anybody has a recommended piece of hardware that I should get?
If you search “water meter pulse output” on amazon you can find several choices. They usually have two wires coming out of the meter. There are brand names like EKM or DAE.
There are also smaller and cheaper ones that come with 3 wires — those are usually not very reliable and tend to generate too many pulses per second so I wouldn’t recommend them, although they are still usable with OpenSprinkler.
I’m also looking for a flow meter, but the only two-wire “pulse output water meter” I can find are on eBay and usually cost much more than AU$77. Most have a display, but I don’t need that – just digital output to my OSPI.
I came across much cheaper Hall Effect Flow Meters, but all of the 3/4″ ones are 3-wire. Would these work at all please?
