Does the Refoss EM16P work without Home Assistant?

Yes, it works standalone with its own app for real-time circuit data, history, and solar monitoring. Home Assistant integration is optional but adds automations, custom dashboards, long-term logging, and circuit-level triggers.

Why is my electricity bill so high?

Appliances like refrigerators, dryers, or EV chargers quietly use a lot of power. This smart power tracker monitors real-time usage per circuit, helping identify high-energy devices and reduce electricity costs by 10–20%.

I don’t want my energy data sent to the cloud. Is it safe?

Yes. All data stays local. Access and manage it via Web UI or local API—no cloud, full control, and easy integration for smart home or automation setups.

Am I wasting solar energy?

Excess solar power often goes unused. A solar power optimizer tracks solar production and automatically directs surplus energy to appliances such as heat pumps or dishwashers, boosting self-consumption and reducing electricity costs.

How can I spot energy-hungry or faulty appliances?

The fastest way to get an ROI is eliminating Vampire Loads — devices that draw power even when “off.” Refoss alerts you to unusual or peak consumption so you can fix them before they drive up costs.
