Well inhale now decided not to use the gsm module from adafruit until I can understand it a bit more. I have however added an Ethernet shield which I have running a webserver which allows me to view all sensor information and what outputs are active. I've also started to add buttons for manual opperation of the pumps but don't quite have them fully working. I've also fixed a little annoying bug which was that I have humidity and temperature both control a single output and which ever one was written first in the code would cause the output to pulse. I've solved this buy having both humidity and temperature have there own output and connect a diode onto each one then join them to the external fan relay out.
