Ray,
Thanks for the response. I mailed the two items back to you so that you can check them out. I’m really not sure what could have went wrong ? If it was a power surge, I would have expected a fuse to pop but the LED is illuminated. Maybe a processor is bad or shift register. I’m not sure how to check these items out. Hopefully your more familiar. Let me know what you think when you get the unit back.
I’m sorry I meant when the station is activated via mobile application there is no change in voltage (24 v ac is not detected). I’m assuming there is no type of protection for a short when an expansion board is connected and I suspect that the shift register, processor or something fried even though there are no visible signs of component failure. This all started when I had a solenoid stick on and possibly short a station connected through the expansion board. The end result is now a mystery, more specifically why none of the stations are working. I think this is unfortunate because sprinklers solenoids are often exposed to moisture from flooded sprinkler boxes, busted sprinkler heads and leaking valves. If a short from a flooded sprinkler box or solenoid failure causes a complete component failure, I can’t see these boards lasting very long in a real time environment. These terminals need some type of protection from corrosion and shorts because its not a matter of if but a matter of when one of these situation presents itself. I am going to send the board back to see if Opensprinkler can figure out what happened.
I am currently using the opensprinkler as a pool controller and I am going to build an API to control the intelliflo pumps using C and PHP so I can control Intelliflo pumps through http requests. I currently am using a Pentair product which only allows me to turn the pump on and off for speeds 1,2,3 and 4. The Intelliflo communicates through rs 485 . I’m planning on disconnecting the UART RX AND UART TX from open sprinkler and using them to communicate with the pool pump. I working on this with three other people and hopefully it will be done in the next month or so.
