Can M1XIN handle 24Vac on a zone?

I decided to go with these relays. They are pretty cheap ($4 each), only use 1/2 watt, and are small. I ordered sockets for them, too, so that the relays can be easily replaced. The sockets have about the same small footprint. I will probably mount them on a couple of perforated prototype boards. Add some terminal blocks for the wiring. Should work and take up the least amount of room.

The main sprinkler screw up problem that I have had to deal with is stuck valves. Sadly, none of this stuff we are talking about will detect that. A flow sensor on the sprinkler line that feeds info to the Elk or some other automation system to warn you when flow is occuring when flow shouldn't be (or vice/versa) is something I would have interest in.

Has anyone ever done something like that?
Pobbisly use a leaf sensor from Hobby Boards to detect 'when' the sprinkler head is on. There are a few posts here about interfacing them to a variety of hardware controls.

Good idea. I kept trying to think of a way to detect flow at the main source that wouldn't cost $500, but you could instead put a contactor on each zone that closes when the line is pressurized. That would be cheaper than flow sensors and would confirm which zone is pressurized.

Ira could go with this concept as well. Instead of checking for an energized valve he could check for a pressurized zone. It would take it to the next level, not just knownig that the valve is supposed to be open but actually is open and spraying.

The killer on this though is running the wires across the lawn back to the elk.
