About
A small home project: a diary of the mains supply in a house at the end of a long rural line.
- three phases, voltage and current, sampled every second;
- short dips below 180 V are kept as events, not averaged away;
- UPS switch-overs and battery self-tests.
Setting up The meter is being installed. Graphs will appear here once data starts flowing.
