OK:) - Good news I have resolved the issues and thought I would update :) As mentioned I used the UNO's as my micro controllers - I decided to use the Pro Minis instead. I set it up on the breadboard and for some reason they worked. I noticed in the code that there was an interrupt command for the Pro Mini and I am not at the coding experience to understand if this might have been the problem when I used the UNO's?? attachInterrupt(1, PushButton, RISING); //May need to change for your Arduino model Anyway the code worked like a charm except now the LCD display kept crashing the system. After MUCH hours trying to figure out why and lots of experiments, I swapped out the Pro Mini for another one and this worked 100%. Having a closer look at my soldering on the A4 and A5 pins became clear where the issue was :) Anyway - its up and running 100% and am very happy. I can now control all the zones from my Domoticz (Raspberry Pi), notifications through Clikatell (SMS) and e-mail works well and I am very chuffed it works!! Thanks to Pete and Bulldog as well as the forum for the help !! You guys rock!! My next project is my Gargage door (open/closed) with the ultrasonic sensors - the wife is always leaving it open!! Cheers Wallis

I had the same error and it turned out that for some reason it was finding the library in a folder in My Documents and also in the Arduino install folder. I renamed the copy in My Documents (I don't remember putting it there so maybe it was older version?) and all was well.
