![]() ![]() 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.
