My install was a fresh install (I moved the old directory out, git cloned, put the data files back in, and rebooted)
Traceback (most recent call last):

Great, will do. But doesn’t the existing interval program now force single zone at a time? I’d like “n zones at a time” actually. Starting to think maybe Interval isn’t for me and I’ll have to get out my node.js weaponry.
With relays, I could easily wire them in series so that when one goes on, any relay AFTER it gets no current and thus can’t go on.
Out of curiosity, why not use relays instead of triacs? The relays could be wired such that it’s impossible to turn on more than one zone (by daisy chaining) while the triacs leave the possibility of doing very bad things (like this).
But I didn’t ask to turn on more than 1 valve. I asked to run a run once program, which should respect the sequential setting that regular programs do. Now, additionally when I put in the 40va transformer, although it didn’t burn, two very bad things happened given that I’m not at the home. 1) Interval started complaining that it couldn’t find data/meta.txt for some reason, and 2) sshd stopped working. So basically I was shut out of the system, had no way to find out the sprinkler status, and had to find somebody to go there and install a regular timer because the OpenSprinkler PI couldn’t be trusted.
The board is great, I don’t think it has inherent issues. The software may cause the board to do bad things though.
Before I had a sprinkler transformer – 300 ma, which blew for sure when I ran a run once program with multiple zones specified. Plus we saw them all turn on, so that was pretty good evidence.
I believe this program to be unsafe as is. It has bugs which can activate a large number of valves and cause electrical problems, in theory including fire.
I’m pretty sure there’s a very dangerous bug in the manual program that causes all selected valves to turn on at some point. Because I’ve blown 1 transformer so far.
I’m confused at this answer… Let’s say I have a 24V 300mA transformer (I do), which is 7.2 VA. And let’s say I have 9 Weathermatic solenoids with a 6.6VA inrush and a 5.5VA hold current (I do!) – I *have* to run sequential right? Because two solenoids active at once would be 11VA? In this guys case he’d need a huge-mongous transformer. Related question – I have two of said transformers and OSPi+expansion board. Is there a way to wire it so that both transformers can be used (assuming I handle the software side of it)
