A live home energy testbed

MK's Energy Testing Lab

One real apartment, metered end to end with off-the-shelf hardware from several vendors and protocols - live, and honest about what it still misses.

What is being measured right now?

Every meter installed in the flat, read live: active kWh, instantaneous load, import and export, voltage and current. The empty bays are the circuits that are not metered yet.

The page checks for a new snapshot every 30s. HA site readings are published by the local collector every 15 minutes.

Energy bill, not currency conversion.

The same measured kWh, priced with public local tariff references in five markets. Each one can be viewed as commercial or residential. Currencies are shown side by side, never converted into each other.
