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. See complite list below.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. Nibe heat pump binding will listening UDP port and parse register data from UDP telegrams.Īrduino based solution, tested with arduino uno + RS485 and Ethernet shields.

#OPENSPRINKLER PI PUMP START RELAY SERIAL#

Nibegw is application read telegram from serial port (need RS-485 adapter), send ACK/NAK to the heat pump and relay untouched telegram to openhab via UDP packet. This can be resolved by nibegw which can be run on unix/linux (e.g raspberry pi) or arduino based boards. Acknowledge (ACK or NAK) should be sent accurately. Unfortunately Nibe has made this tricky, telegram from heat pump should be acknowledged, otherwise pump will raise an alarm and go in alarm state. Those 20 registers can be configured via Nibe ModbusManager application. When modbus adapter support is enabled from heat pump UI, heat pump will start to send telegram ones every now and then. Binding should be compatible at least F1145 and F1245 heat pump models. Nibe heat pump binding is used to get live data from from Nibe heat pumps without modbus adapter.
