I bought a OpenSprinkler (OS30AC) less than a year ago and it worked great. Earlier this week, I noticed that it was offline and the board appeared dead. I went ahead and ordered a new one because we need a lot of things watered but I’d like to get the old one working. I didn’t see anything about warranties so I think that I should have a spare standing by now. 🙂
The power AC power supply is good and I disassembled the board, removed the zone driver board, then put a USB power supply on the top logic board. In all cases (fully assembled with AC PS and disassembled with USB power supply), I just get a brief flash on the blue ESP8266 LED. I have not done any further debugging, as it has been a busy week. Are they are any common component failures that I should check? I have all the necessary equipment to check things out but maybe someone has already had this failure and figured it out. Thanks for any advice.
