While I have no doubt that’s all true it doesn’t help with where to start to understand how to use it.
Yes, second master station. It comes up as M, the same as the first master in the web interface.
Is there any limitation to which station is the master? In the API doc (maybe an old one) the master could only be assigned to the first 8 stations. I was thinking of putting mine at the top end at 39 and 40. I was able to assign them in the web interface. Am I going to end up with any issues with the API? I don’t plan to use the API to change the stations but want to use the API to switch between master 1 and master 2.
The white injection molded case I have is the same one shown in the video link I posted about the new enclosure. At 25 seconds you can (not a good view but it is visible) the area where the 3 push button holes are. That’s where the ethernet jack is located for OSPi.
Here’s is a picture of a case like mine. Note it doesn’t have the OSPi board in the picture.
https://rayshobby.net/wordpress/wp-content/uploads/2013/06/IMG_3013.jpgMy real issue is not that the old case needs modification to work – I knew that.
I was more interested in the stand off info. And a drawing with the locations of the other connector cutouts would be great if anyone has that.
Found answers to some of my questions here:

I got some of my questions answered here:
It answered:
The old enclosure didn’t have holes for the USB or Ethernet.
The large holes haven’t changed and still in the same place (at least at the time of the video).It didn’t answer what the stand off hardware is. I found this github announcement
https://github.com/rayshobby/opensprinkler/tree/master/OpenSprinkler%20Pi/hardware
and the github apparently has the layouts of the enclosure so I can modify it with cutouts. The google drive link there DOESN’T have the current board or standoff info in spite of the fact that it says it has all versions. It only has up to 1.2. I think the info is probably posted somewhere but very frustrating trying to find the various relevant info…Found the manual I think. And where to set the master stations. The second station comes up marked M in the web interface not N. Is this expected?
digitalbits, I suggest you post the code or perhaps you could fork what is on github and leave it there. It may be that others would help out.
Made a mistake pasting the link in the OP. It was:
https://opensprinkler.freshdesk.com/support/solutions/articles/5000164006-using-a-different-server-for-ui-assetsI found the document. Same name but different URL…
https://openthings.freshdesk.com/support/solutions/articles/5000164006-using-a-different-server-for-ui-assetsWhat else does the controller rely on the internet for? If I support the ui files locally what won’t work and are there work arounds for them?
As to how it fits into the case, all the header connections are brought to the edge of the OSPi board so a tall header can be used to attach a board and put it above the Pi. Adafruit has a LCD with push buttons for the Pi that will work. And a tall case is easy to do now that the case is laser cut (if you have access to a laser…).
There are some postings about similar things that might help you if you are able to do some code hacking. I am looking into that myself.
Was only able to find one that has available code.
https://opensprinkler.com/forums/topic/ospi-with-lcd-and-push-buttons/Would be really great to have this work with the existing OSPi board.
BTW, where are current compile instructions? I found some pages that refer to it but the links are dead. And the more current stuff I found (I think…) only has details for Arduino and OS 3.0.
One thing to keep in mind… POE does not eliminate the need for 24VAC for the zone valves. It would just provide an alternate source for the processor which is the main reason I did it. The Ethernet wiring isn’t heavy enough to use for the 24VAC.
I did something similar but not completely meeting the POE specs. I bought a set of power injector adapters that allow power to be put on the unused ethernet conductors at the router and broken out at the Pi. Then got a 12V to 5V regulator board for the Pi end. Use a wall wart at the router plugged into a UPS. I damaged the power supply IC on the OSPi so I removed it. Now I supply power to the Pi power port. Eliminates SD card corruption for when I lose power which does happen from time to time. Would be great to have at least a jumper to disable the on board power supply. Someone probably makes a breakout adapter that meets POE specs if there was a jumper or you disable the OSPi power supply.
Appreciate the reply and understand you can’t add every possible option to the program. Just hoping someone else has done something similar that I can leverage. Or even a simple script that does something different that will get me started. Looks like a script is the way to go for this.
Still don’t see why you are suggesting the rain sensor input or how it might work. It seems totally unworkable to me but perhaps there are details of how the rain input works that I am missing. As I see it the two possible scenarios are:
If the rain sensor input is set up as active high (high level indicates rain and shuts off system)
With pump off pressure is zero so the rain sensor is inactive allowing the pump to start. Once pressure builds up it registers as rain and shuts the unit off. I am not sure if shutdown would be immediate or just disable the next cycle. If for the next cycle the pump would be off and reset the sensor input and allow it to start again. If the pressure signal goes away while running the rain signal would go away and not shut down the pump.The other option is if the rain sensor input is set to active low (low level indicates rain and shuts off the system).
With pump off there is no input to the sensor input which shuts down the system. So it never starts.Thanks but I don’t see how that will work. If I set it up so that no pressure is seen as rain to shut off the system when the pump isn’t working properly then it will never start because when the pump is off it will think it has rained. Am I missing something?
I want a little more smarts than just on/off so have posted for this in the software section. Would be great to find code that is close to this because my coding skills are limited.
Making independent software on the Pi makes a lot of sense. Thanks for the suggestion – I hadn’t considered that.
The pressure sensor will have two uses. Check that the pump is actually pumping and hasn’t lost prime. And check that the output pressure is not too much lower than normal (set points to be determined). Basic function that I am thinking of (set points subject to change) is:
Within 2 minutes of startup have pressure of at least 30 PSI. If not shutdown pump and send email notification.
If the pressure drops below 35 PSI send a warning email that the pressure is low so I know to clean the filter.
Unless I incorporate this into OS I will run the pump signal from OS to an input on Arduino. Then an output pin on Arduino will control the relay for the pump allowing shutoff of the pump independent of OS. Probably just an Arduino Uno that sends status messages to the PI over USB serial. Then a script on the Pi that can send emails (and possibly make API calls to OS). Not putting the Arduino directly on the network. I’ve done similar things like this before – it could probably be done in a more technically elegant way but this way is fairly simple and easy and gets the job done.
If I could do this in OS that would be great but I don’t want a major project.
It’s probably somewhere in the documentation but I figured it out – Number of zones is set by clicking the icon in the lower left of the web page, the edit options, then station handling. They can be named by clicking on the gear to the right on the list of zones.
Doh… In looking over my wiring it looks like I misconnected output of OSPi to output of expansion zone shorting the power supply. The regulator is now shorted and outputs 37V instead of 5V. Not sure if I will try to repair this myself or send it in. Still would like to get a parts list. The only one I found on line (github) is way out of date and uses a different part number regulator.
Where is a parts list for the OSPi version 1.42+?
Would also like to get a parts list for the zone expansion board.
Ray,
I bought my OSPi some time ago, I am guessing a couple years ago so my purchase may be close to the same time as the others in this thread. Finally getting around to changing over to this. When I powered up the board with 24VAC with the Pi installed there was a puff of smoke so I pulled the power immediately. There is a burn mark next to F2. The fuse tests ok when the meter probes are placed on the terminals on the fuse but when I put them on the pads on the board it shows open. The solder is minimal but looks connected. Obviously it isn’t. I am considering touching up the solder on this part since I work on this type of stuff regularly. Seems like this might have been a processing problem at the time since others had the same issue? Fortunately my Pi B+ still runs and appears to be ok. Please advise.
Jim
I started here:
https://openthings.freshdesk.com/support/solutions/articles/5000631599-installing-and-updating-the-unified-firmwareIf I click on (Under “related documents” API documents I end up at an open garage document. Maybe this is intended and just not a clear title for this document?
If I click on “API Document — Firmware 2.1.5” I get a page that says “Maybe you mistyped…” and it gives a link back to the home page. It is a bad link.
Yes, I am looking for OSPi info.
Thanks
Ray,
I was basing the IPv6 only off a statement in the tread you referenced. It seemed a bit strange that such would be the case and I see you have posted in that thread to set the record straight. Thanks for clearing that up.
Jim
