The "Download Your Usage Data" files on the "Usage" page gives half hourly readings from recently to two years back. This is good for manual long-term trend analysis.
Is there a way to get the current readings quickly, half-hour by half-hour, or quicker? Can it be done in real-time or near real-time? Is there an API?
I would like to run a monitoring system that can continually display loads, and even switch loads based on current conditions. (A phone app would not be any use.)
