It looks like the sd.json file in the OSPi/data directory is missing a couple of logging related keys. If you saved your setting by backing up and then restoring the files in the data directory, or just replaced the ospi.py file that could cause this problem 😳

You should be able for fix the problem by editing the sd.json file. It is just a text file. Add the following:
, “lg”: “”, “lr”: “100”
just before the final curly brace , }

You could also just replace the file with the the one from the update but you will loose some of your settings.

In the July 21st update of the ospi.py file I added some error checking which should have eliminated the error.

At this point the Python interval program does not use the RTC. It will probably be added at some point.

The purpose of the RTC is to provide a stable time source when there is not an internet connection.

Keep in mind that with some updates it is only necessary to replace the ospi.py Python file and it is not necessary to backup and restore the config files.
In other updates there have been changes to various other files and it is best to do a full re-install. This will likely be the case when the parallel/sequential option is added.

I just discovered that it is easy to auto detect the Pi board rev and have implemented code to set the GPIO pin configuration automatically. This eliminates the need to manually edit the code tor use with Rev 1 boards.

Hi,

I’m currently working on the Run once program code to add some missing master (station/valve/zone) functionality. I’ll look at this issue also.

Thanks for reporting it.

I must say that Ray has managed to cram a lot of features into a small amount of micro controller code. You don’t really appreciate it until you try to replicate it.

Hi Ingo,

This problem has several parts to it. I am working on it as quickly as my time allows.
It may take another day or so to fix completely. I’ll post a message here when a new update has been posted with the fix.

Sorry for the problems but this is still under development.

Dan

[Dan in CA]

It’s a bug alright.

I’ll work on a fix.

Dan

djagerif,

Could be a bug. I’ll check.

How are you switching the zone on? by a program or manual?

Hi Andrew,

I just checked the preview on my OSPi and it seems to be displaying correctly.

I have the latest update installed.

Dan

[Dan in CA]

djagerif,

Sorry no one got back to you in a timely manner. Although I wouldn’t have had a good answer for you.

What you worked out is something I was planning to investigate because I want to add some additional features without modifying the ospi.py program itself. I will add the code for importing a custom module to ospi.py and include a file named ospi_addon.py in the distribution so that anyone who wants to add custom features will have a starting point.

This is a great addition to the project. Thanks for your contribution.

Hi all,

I’ve been offline for a few days. Traveled to Arizona and got to observe some dry farming methods that use little or no irrigation at all. When we arrived in AZ the temperature was predicted to be 120 deg.F (48.9 deg. C) but it didn’t reach that and there were thunder showers.

I am looking through the posts from the last week or so and will try to fix any open bugs. I will also be working on adding the sequential option that is in version 1.8.3 of the OS firmware.

The next update will also include aradke’s suggestion for adding the faveicon. All that required was is to download the icon file and place it in the icons directory under OSPi/static/images then add the following line to the “home” class in ospi.py.

homepg += 'n'

The last update was supposed to get posted to Ray’s Github account. I am just learning to use Github and things should work better going forward.

Thanks to salbahra for all the help with bugs.

The latest update on GitHub should have the hang bug fixed.

I have already taken out the “print nstlst” line.
I was using it to help figure out how to implement the last run log for manual mode operations with an optional timer value. I think I have that working now even if you start more that one station.

I’m also testing a fix for a bug that does not clear the station status on the main page after running several irrigation programs. I won’t be sure how that works until tomorrow morning. Every time I test it manually it works as it should.

cmwahlqu,

The -1 in the number of log records indicates that the log file has a problem. Click the “Delete All” button to clear the file.

If you start the interval program manually and then log out of the pi, the program will stop running. See the last instruction in the readme on GhtHub:
https://github.com/rayshobby/opensprinkler/tree/master/OpenSprinkler%20Pi/software/demos/interval_program
Once you have the interval program setup to start automatically and run as root, your irrigation programs should run as expected.

Simon,

The “Unaurthorized” message indicates that you did not enter the password (opendoor) before clicking the Submit Changes” button.

Thanks for the bug reports. I will see what I can do.

Regarding the daylight time situation, I thought that might be a problem. Maybe the best thing would be to remove it. Even in locations that use daylight time there is really no reason for an irrigation schedule to change. It can just stay on standard time.

Thanks for sharing Kenbob.

No need to apologize for your programming experience. You are figuring things out, tweaking the code to make it do what you want and hopefully having some fun along the way. That’s what counts.

I have downloaded the zonecheck.zip file and will check it out. The Sprinklers.php was written by David B. Gustovson and I am not that familiar with PHP.

I’m sure your efforts on this will be helpful to others.

Thanks again.

Dan

[Dan in CA]

That’s really cool!

I was wondering if you could share the changes you made to the zonecheck.py scripts. I wrote that a while back when I was just getting started with Python programming and did not include any error checking. I’m sure your updates would be useful for other users as well.

Hi Ray,

The Wiki is a great Idea!
I have a post about using a flash drive for storing log file on the Pi but when I tried repeatedly to create an account so I could post it, I got the following error.

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:

(SQL query hidden)

from within function “User::addToDatabase”. Database returned error “1142: INSERT command denied to user ‘dbo465905316’@’74.208.180.188’ for table ‘user’ (db465905316.db.1and1.com)”

I hope it gets fixed soon.

Hi kenbob,

I see the problem.
If you are into some Python hacking, change line 449 from this:

if qdict !=” and qdict == qdict: save(‘pwd’, base64.b64encode(qdict))

to this:

if qdict !=” and qdict == qdict: sd = base64.b64encode(qdict)

Just the part after the colon has changed. The program no longer uses the pwd.txt file.

I will be submitting an updated version of the program in the next day or so. The updated version will also include a logging capability.

The combination of Raspberry Pi and OpenSprinkler seems to be working quite well.

I posted the steps I used to get the pi and OpenSprinkler working together on my blog. At this point the Pi serves the JaveScript files and icons for the UI and handles logging of irrigation events.

I am in the process of writing a python module for interacting with OpenSprinkler. It will allow to write python programs which can be run on the Pi or other computer on the network that will be able to check and set irrigation schedules on OpenSprinkler. So far I have python functions that can change the Water Level %, set Rain Delay, read and change Run-Once Program settings and do things like set manual mode, reboot, and dis/enable OpenSprinkler. Once the module is ready I will be able to start working on some programs that tweak irrigation schedules based on evapotranspiration (ET) estimates from a local weather station. I will post here when the python module is available.

Here is a resource that might be useful:
http://www.usbr.gov/waterconservation/docs/SmartController.pdf

It examines weather based irrigation systems. Be sure to check out the section “Weather-Based Irrigation Control System Principles” starting on page 7 of the document (page 17 in the PDF).
