I'm thinking of making a simple information page with just the basics. Maybe battery/array voltage, watts being produced and battery temperature which should match outside temperature most of the time. Maybe some color to represent the control state i.e. bulk, absorption, float or night. And possibly some buttons to bring up individual graphs. Then mounting this somewhere in the living area. Not sure yet.
I also created another RRD that only gets updated once per day at 11:59pm. I'm storing the amp-hour produced to date from the charge controller. From that, I can graph daily production. It's a boring graph right now as it has only one data point.
