to days ago I have launched my new Rachio 3 with new 6-zone watering of my wife’s garden.
Unfortunately, I hit some troubles and need help.
Rachio app was able to start watering for each of the zones, but it was not able to stop it - for none of them. I mean:
- “test runs” during zone setup. Here it started watering, reported end of watering, but actually water was flowing.
- manual run from the app. the same behaviour
- manual run from the console. Neither “stop” nor “pause” button did stop actual watering though sometimes when I was switching to another zone it stopped watering.
I found an article that it might be that DC valves would behave like that, but I do have AC valves (Hunter PGV-100G-B 1"). So that’s not the case.
To make it more strange, when two zones were scheduled for watering, starting a new zone (or switch to a new zone) was stopping watering of the previous zone.
Now I do not know where to search for the problem.
Does polarity of cables attached to the valves have any meaning - despite this is AC? Should I try changing them or “short-circuiting” manually to see if valve reacts at all?
I must say I bought Rachio 3 with great hopes - for convenience and for bringing some modern high-tech home. I am disappointed at the moment, though of course I cannot exclude this is a problem with wiring or valves themselves. Though “valves” I assume as not very likely - all 6 of them are brand new, all six from Hunter, “professional-grade” (at least that is what Hunter writes about them).
Any suggestions on how to diagnose the problem and what to check (and of course - how to fix it) would be very useful.
— UPDATE —
yesterday I have tested the solenoids and Rachio 3 in a simplified configuration - just with one valve.
- polarity has no meaning (As expected, but I felt so confused and topic is new to me, so I needed to work all hypothesis from ground up). The solenoids are meant for AC (Hunter PGV 100B-G).
- Ration sends current to the solenoid, opening the valve - all nice and as expected. BUT when it says that it finished watering OR when I press “stop watering button” - Rachio console leds signal watering is finished, Rachio app says the same, yet solenoid gets current despite this. Thus watering continues. Getting power off or wire out helps to force stop it.
- Thus - solenoids are ok, they open when there is current, and close - when there is none. Valves are not stuck. Only once suspect remains on scene - Rachio 3 and something inside that should break the circuit, when told to do so, by the app, but does not manage to do it.
- I do not use a standard power supplier, as I live in Poland, and have not only different power outlets (this I could easily adapt mechanically), but also different voltage. Or, would the Rachio adapter work with ~230V?
I have reported both the problem and the aforementioned diagnosis to Rachio support, but got nothing back. I suppose I will send the controller back.
Any help, comments, advise?
