Firmware updated, breakout box installed, programming figured out. This controller is superb
I'm planning more expansions to it now that I'm seeing the potential. I plan to add a door switch to turn on my refugium light so I can see what I'm doing in the sump, another float switch for high water level (all ready have one for low sump level), and perhaps a water leak alarm.
Question for those in the know, what do ORP and Conductivity tell you that is usefull as far as controlling anything? Aside from just reference data, is there any real purpose to having those sensors? Not currently planning to add those unless there is some useful purpose for them.
