Refoss Smart Home Energy Monitor with Open API, Home Assistant, No Cloud – 16 Circuit 60A Sensors, Real-Time Electricity Usage Monitor, Solar Metering, ETL Certified, EM16P
Product Description
The Refoss EM16P Smart Home Energy Monitor provides real-time, circuit-level electricity monitoring with local data access, Open API, MQTT, and native Home Assistant integration. It supports 2 main circuit sensors and 16 branch circuit sensors, allowing you to monitor voltage, current, active power, and power factor across your home electrical system.
Designed for solar homes, the EM16P can help maximize solar self-consumption through automation and peak management. Local access through the built-in Web UI, Open API, and MQTT keeps energy data within your home network without requiring cloud services or subscriptions. With up to 5 years of daily historical data, circuit-level alerts, ±1% accuracy at supported current ranges, and clamp-on installation, it provides detailed energy insights for home energy management.
