The measurement dashboard

Capital efficiency, energy metrics, performance, and economic displacement — entered manually today, with four real integration routes ready to take over the moment hardware is installed.

Record a real reading, workload run, or tariff value below. Calculations stay blank at the zero baseline until evidence is entered; saved entries remain in this browser and can later be replaced by the existing telemetry adapters.

Live telemetry

These four integrations are wired up and ready to receive real readings — Home Assistant, Prometheus/DCGM, a UPS monitoring bridge, and a solar inverter API. None of the underlying hardware is installed yet, so every card below reports its honest current state rather than a fabricated number. Once Hearthpower, Hearththermal, and Hearthmind Software configure their respective environment variables, this panel starts showing real readings automatically.
