Went into the App, manually entered 10 seconds and clicked “save”. I heared a “click” comming from the valve and after time was up… nothing. No clicking sound to signal “ok, I´m done”. Did the test a few times -> no click at the beginning none at the end. To me it seems that the valve gets an “open” signal but no “close” signal and the “open” signal only the first time you start manually. Then just nothing. 🙁
Then I disconnected the valve from the OpenSprinkler Pi noticing it got really hot at the upper part where the cables are. Connected it directly to the 24VAC, plugged it in -> click. Plugged it out -> click.
Raspberry Pi and OpenSprinkler Pi are up and running using the 24VAC so I´m a bit confused where I failed. Using a “mains testing screwdriver” (yeah, those things that tell you “nope, no current, it´s safe” and then you die 🙂 ) I noticed that the COM screws and the S01-S08 screws all are under power. Me, as a complete n00b does think this might be normal…? Perhaps?
