Refoss is a smart home brand active since 2016, best known for its multi-channel energy monitors and for smart plugs, switches and garage door openers. Its energy monitors clamp onto the mains and branch circuits and expose the readings through a local web UI, an open JSON-RPC API and MQTT, so they run without any cloud account. Refoss devices integrate natively with Home Assistant, Alexa, Google Home and Apple HomeKit.
