I got OpenSpinkler 3.0 in the last month or so and am *pumped* about getting it up and running. Sadly, I am getting a very odd behavior (or something I am ignorant of being normal 🙂 ); here’s the situation:
– I have the AC model, which came with the 24 VAC/1000 mA adapter.
– My solenoids are the appropriate 24 VAC ones, and trigger fine on my old timer. They originally ran maybe 2 or 3 times with OpenSprinkler as well.
– What I see now is that, with or without sprinkler station/common wires attached, measuring the current between the active station and Common starts at 19 mA (reported in the app as well) and then pretty rapidly drops from there as the timer counts down. The important part is that my sprinklers don’t trigger in this scenario (otherwise I don’t think I’d care too much about the amperage dropping down 🙂 ). The same things happens when I use a micro-USB as well.
What do you think? Funny power unit on the board? Some other component not doing its job?
Re. #47410: Have you tried the test with the micro-USB power removed altogether? It isn’t made to power your valves. The other test to perform is to wire a valve directly to the 24 VAC/1000 mA adapter, ideally with an ammeter to measure the current draw there. (All my valves require 400 – 500 mA.)
I wish I could explain how I remember seeing only 19 mA when my stations were active, but I (thankfully) couldn’t replicate it last night, rather I’d get a jump up to ~480 mA and then settle in at 220-230 mA. Lastly, the majority of my stations *still* weren’t letting water out…it turned out to be stubborn valves – I adjusted one of the pressure mechanisms on the non-working stations and now they all gloriously work!
