Refoss EM06P

Refoss · EM06P

The Refoss EM06P is a smart energy monitor designed for residential and professional installations that require detailed tracking of electricity consumption and generation. It features six independent channels through current clamps, allowing you to monitor individual circuits or combine channels to represent full three-phase loads. One of its key features is its open API with support for HTTP JSON-RPC 2.0, MQTT, and WebSocket, making fully local integration with Home Assistant easy without relying on cloud services. The EM06P is especially useful for photovoltaic installations, as it can monitor solar production, energy import and export, and support Zero Feed-In strategies to maximize self-consumption. It also includes a local web interface, free historical storage for several years, and ±1% measurement accuracy, offering a very complete solution for advanced energy management.
