Know exactly where every watt is going, circuit by circuit.
A custom energy hub reading 16 independent circuits via CT clamps — live consumption data, historical trends, and anomaly alerts piped directly into Home Assistant dashboards. Built for a full building, not a single outlet.
From CT clamp to live dashboard — a walkthrough of the whole pipeline.

Granular enough to catch a fridge compressor cycling wrong — not just a whole-building average.
16 independent current-transformer clamps — non-invasive, clip-on installation with no rewiring required.
InfluxDB time-series storage with Grafana dashboards — see today's usage or last year's, side by side.
Every circuit appears as its own entity in HA — usable directly in automations, alerts, and dashboards.
Get notified when a circuit draws outside its normal pattern — a failing compressor, a space heater left on.
Single Ethernet run for power and data — clean installation next to the panel it's monitoring.
All data stored on-site. No subscription, no cloud dependency, no vendor lock-in.
Problems and waste that a monthly bill can never show you.
Spot HVAC or lighting still running in an empty rental unit before it shows up on the bill.
Catch a compressor or pump drawing abnormal current — often the earliest sign of a failure.
Per-circuit data makes fair, transparent usage-based billing possible in multi-unit buildings.
Feed live consumption data into HA automations — shed load, trigger alerts, or log events.
Non-invasive CT clamps mean no rewiring — install without an electrician re-terminating every circuit.

If you don't know which circuit is wasting money, you can't fix it. Let's get real numbers for your building.
