Open API & Flexible Integration: The Refoss R11 is a single channel smart relay with WiFi control and Bluetooth quick connection. It allows independent control of household appliances, circuits and office equipment. Use the open JSON-RPC 2.0 API (via HTTP, MQTT or Webhook protocol) for your own solutions or connect to existing systems - for example upgrading your dryer to a smart device. Seamlessly integrate it into your dashboard or IoT ecosystem. The choice is yours! Power Management & Efficiency Optimization: Real-time monitoring of device power consumption with consumption reports to identify power-intensive devices. Set limits for water heaters: automatic shut-off when threshold is exceeded or adjustment of the heating plan after electricity tariff times to reduce costs. Multi-platform control (voice, remote & local integration): Connect to Amazon Alexa/Google Home via the Refoss Cloud for voice-controlled on/off of lights or sockets. Integration with Home Assistant or third-party automation systems via the Open API for scenarios such as "Welcome Home Mode" - including simultaneous activation of lights and electric fans for a cosy ambience. Compact & retrofit friendly: With a compact design, the R11 can be easily installed behind switches or sockets. Retrofit time: less than 10 minutes. Local Safety & Developer Support: Built-in over-voltage, over-current, overload and short circuit protection. Local web control and API connectivity for stable operation - ideal for DIY users and developers.
