    I have extended ospiLCD to look at pump pressure via the a/d on OSPi and send emails when pressure is out of range. When it gets too far out it will reset the active zones and send an email. I started with ospiLCD mainly because it was a fairly simple place to start that used the API. I used total minutes as an indication the system was running – pump master zone would be better I suppose but I didn’t know quite how to do that. I disabled the LCD display but left the code in the file so it can be used if needed. I changed it to run a while loop forever rather than relying on cron to rerun it as I needed to do some timing. I haven’t finished testing it but would welcome some other eyes on it and testing. For others wanting to put together something in python using the API I suggest they look at ospiLCD if they need some info with how things are done.

    What’s the best/preferred way to share the code? It’s about a 10k file size.

    You could use a gist: https://gist.github.com/

    Is this a direct modification to the firmware? If so, perhaps make a pull request?

    Not familiar with how github works – I have only gotten a few files there – but a pull request looks like a good way to go. I will look into that.

    Hi Jim,
    I am interested in adding the exact feature you have been talking about (pressure sensors across a filter) Did you get it to work?

    It works very well. I have one sensor on the output of the filter and detect when it gets too low due to a plugged filter or problem with the pump pickup and shut down the system. I also have it send me an email 1 minute after startup of the pressure and notice if it shuts down. I have been meaning to post it somewhere but haven’t figured out github yet… I will try to do that.

    I finally put this on github. Not really familiar with how github works so I may have done some things in a non-preferred way but it is here:

    https://github.com/jimls/ospiLCD

    It works. Not claiming it is good coding… 🙂

    I see it includes the original files which wasn’t my intent. My files are the new ones.

    Hope this helps others…

    with the new firmware it no longer works

    I never got any reports that anyone got this working. That would be useful and nice to know. You say “it no longer works” – was it ever working for you? Surprised it doesn’t work because the API probably hasn’t changed. I don’t intend to update firmware (at least at this point) so it works fine for me and I have limited time to support this but I would welcome others additions/improvements/etc. Without more information it’s going to be hard for anyone to help you.

    Hi Jim,

    I am interested in adding a pressure sensor to my system as well to do two things. First, shut off the irrigation system based on a set pressure. Second, record the water pressure when the system is running. Any help you can share is greatly appreciated. Thanks in advance.

    This will require modifying the firmware. I don’t know what type of pressure sensor you have, and what type of signal it outputs. Attaching such a sensor to the controller requires figuring out how the controller can read the signal from the sensor.
