With the awesome mobile app described at: http://rayshobby.net/?p=6409

there is a need to keep ospi.py in sync with the Samer’s expectations. For example, his patch file didn’t work on the “older” (original?) version. Updating to the latest in Github worked fine. But I’m not clear what other files need to be updated.

What is the best practice for keeping the version running on the OSPi current?

Thanks,

I just powered off the OSPi and rebooted. I continue to received “random” results when running sudo ./ospi_selftest.

Recommendation? Should I return the units? I don’t want to wait for my 30 days to pass.

The saga continues. I’ve left my setup running for > 6 hours on the bench. The Pi appears to be operating as expected. Running the demo programs ospi.py and ospi_manual.py results in some pretty strange behavior. The expansion unit is attached. I haven’t tested every pair of zones but I’m seeing some strange interaction when turning on zones 1 & 16. For example, when running ospi_manual I turn on zone 1 but don’t measure a voltage change. I then turn on zone 16; zone 1 now measures 24vac. Then some clicking on/off between zone 1 and 16 will ultimately result in one or both zones turning off. No rhyme or reason that I can discern. Is there a way to “reset” the “shift registers”? Other ideas on how to debug or proceed?

Thanks,

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?
