Energy Monitor
An energy monitor measures voltage, current, and power on a circuit or whole panel and reports it to Home Assistant. It turns raw consumption into data you can automate on, bill against, and spot problems with.
An energy monitor reads the electricity flowing through a single load, a circuit, or an entire breaker panel and streams the numbers to Home Assistant. Some clamp around mains conductors with current transformers; others sit inline behind a socket or switch. The result is live and historical data on what a home actually draws.
How Selora AI uses energy monitors
- Whole-home and per-circuit visibility so installers can show clients exactly where power goes.
- Cost and tariff recipes that shift loads to cheaper hours or cap demand during peak pricing.
- Anomaly alerts that flag an always-on load, a tripped circuit, or a device left running.
Why energy monitoring matters
Measurement is the first step to savings. Once consumption is visible, automations can act on it, and homeowners get a clear picture of the return on their smart home investment.
