“Then dis-assembled the set up, removed the BBB (to isolate the problem) and connected the power and checked with the multimeter directly against the pins. No power.” I don’t understand what this means: without the BBB, the OSBo cannot turn on any station, it needs BBB to send control command to it, so obviously without it there won’t be any output voltage on any station.
When you used multimeter to test, are you actually running the OpenSprinkler program, or at least the test program, so you know the software is actually turning on a station?
As I said, we test each single board and make sure every station works on each board. The likelihood of all stations failing is quite small. Anyways, if you still can’t figure out, send an email to [email protected] and we can have you return the board to check it for you.
