Earth Notes: Off-Grid Stats from the RPi powermng Utility

Updated 2019-09-25 20:58 GMT.
Power-management system statistics for the off-grid system from 2014.
data
Collected logs from the powermng power manager utility on the Raspberry Pi.

The Raspberry Pi monitors and manages power, including some interaction with the grid by moving small loads off-grid (the 'dump' load) when possible.

This is managed with a small C++ utility that runs every ten minutes to compute system state from local and remote sensors. It sets flags in the filesystem for other programs to use to be sensitive to available energy, from Java Web servers to makefiles.
