Thanks for the reply. I have the unit back on the bench and now I’m really confused.

I connected a second Pi to help eliminate the Pi as the problem.

After a fresh start from power off I measure voltage between each zone and common I received something around 4vac. Is this expected?

I then run ospi_selftest. Sometimes one of the zones will measure 24vac when activated but there doesn’t appear to be a pattern. Furthermore, in any one run of self_test usually only 1 zone appears to operate normally (though sometimes 2) and it doesn’t tend to be the same zone.

Thanks for the help,

Tim

EDIT 1: I just reconnected the original Pi and after 5 runs of self_test I didn’t measure 24vac on any of the zones.

EDIT 2: Hum, and now it seems to be working as expected with the 2nd Pi. I’ll continue testing on the bench, then attach the extension, and then reattach to actual valves.

EDIT 3: The extension is now working properly on the bench as well. I still measure ~4vac on closed zones, is that correct?

We are currently away till Sunday July 20. Orders placed during this time will be shipped on Monday July 21. Thank you for your understanding!
