Refoss sells smart-home and energy-monitoring devices with a strong local-control and Open API positioning, including circuit-level energy monitors for Home Assistant and privacy-focused home automation setups.
A local-first 18-circuit CT energy monitor for Home Assistant households that want whole-home, branch-circuit, and solar/feed-in visibility.
Refoss is a smart-home hardware brand focused on local-first automation products, smart energy monitors, switches, relays, and plugs. Its newer Open API product line is positioned for homeowners and DIY users who want local Web access, MQTT, JSON-RPC style APIs, Home Assistant integration, and reduced dependence on vendor cloud services.
For EnergyMeterHub, Refoss is most relevant in the residential energy-monitoring category, especially for circuit-level CT monitors such as the EM16P and EM06P. These products sit near Emporia Vue, Shelly Pro 3EM, and other panel-monitoring options, but the Open API line is notable because Refoss explicitly markets local access, MQTT, and app-free operation for privacy-minded users.
