Opensprinkler pi get firmeware9/20/2023 ![]() ![]() I was aware of the OpenSprinkler project and it was the one I had intended to use. Next was what software to run or roll my own! Documentation for the tool is at their page software that is quite brief – on testing with the meter it seems that it just pulses each zone and does not latch for the test period – no problems, it is just for testing and all works ok! I used wget to get a copy on the Pi and it happily enabled each of the ports on my new board. On their WIKI site I found the TSSPiTest software. With the hardware all mounted in its new enclosure and 24v run into the TIAO board I could start some checks to make sure all was working. With the basic system built, I could mount the board in one of my old controller housings that was going to also provide my 24v AC supply – this old system had also been providing the 24v AC supply for my CBUS system for the last few years! During the install I made the usual changes: hostname ‘irrigation’, enable SSH, locale en-au.utf-8, timezone Australia/Perth, sudo passwd. The initial build was quite standard … NOOBS started it all off in the standard way with everything sitting on my test bench. I live in Australia, so the board took a little over 2 weeks to arrive after order – quite good I thought, but I was expecting it to take a little longer and it clashed with a few other ‘life’ projects and my new supply of MicroSD cards hadn’t arrived yet!Īssembly took 5 minutes – as you can see from the below photo, I used an old Pi v2B board (that was originally used as media centre at my work house and has had a few other ‘tasks’ since!). The only decision I had left was stay with my Pi thoughts or go for the Arduino version – since I couldn’t find specific details on the Arduino chip being used and hence its memory capacity, etc, I decided on the Pi version as I also had an idea what I wanted to ‘play’ with for functionality but hadn’t defined it too well either yet! I had 16 zones that are controlled by the Pi GPIO so I have control over each zone easily as well as a rain sensor (digital) input – so it met my immediate requirements. Wandering around the world wide wonder one night I came across the “ TIAO Smart Sprinkler Pi V2” board that took my fancy. My current system is ‘ok’ but I need to get rid of original 8 zone restriction and look at some advanced control … I could have expanded my CBUS system, but it meant buying another low voltage relay controller for around AUD400 and then analogue input devices – this adds up real fast and would still take a lot of coding to get it to do what I want! While this would have been fun a few years back, I would rather play with a Pi (or 4!) and then interface them back into CBUS system. My initial controller was one I brought from the previous place to ‘get things going’ that was quickly ‘upgraded’ to run from my initial CBUS black and white screen, then to my CBUS colour screen and now that my needs are getting more complex I am moving to a Pi! I started this process in the same manner – making sure all the infrastructure was in place at build time and thus allowing the control system and various other parts to be ‘upgraded’ as I go along. ![]() When I built my place a ‘few’ years back, I had plans of making my garden as smart as the rest of the rest of the place. The OSPi v3.0 kit includes the enclosure (with a clear acrylic window), assembled and tested OSPi circuit board and terminal blocks. Small flathead screwdriver, Phillips head screwdriver, and needle nose electronics plier Tapered machine screws to attach back to front of OpenSprinkler housing (screw head must fit into OSPi slot)Ĩx 8 inch solid wire (same gauge as Rainbird wire) Rainbird irrigation system with 7 zones and 24V AC sprinkler valves (OSPi can handle more zones with additional parts) Micro USB to USB cable 3ft from Amazon $5.49 Orbit Water Conservation Sprinkler System Rain/Freeze Sensor, Amazon $30.11 SanDisk Ultra 16GB Ultra Micro SDHC UHS-I/Class 10 Card with Adapter (SDSQUNC-016G-GN6MA) from Amazon $6.60 OpenSprinkler OS3.0 AC-powered (including 24VAC power adapter, US) $166.00 A case and power supply for the Raspberry are not needed. The parts below seem to work best for me. In another Raspberry Pi project, I measured, tested and experimented with various kits and components. ![]()
