I will be using the older X11 control system for my lights again( to turn them on and off by computer) I just wondering if anyone has tried using the X11 system to report back Ph . light level, temps or any other parameters of interest. I can see will a lot of work would be required for the first unit and quite a bit less for succeeding units. Maybe use the basic stamp to collect for 3 or four aquariums and send the data back. Any thoughts.
