About this item
- 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.
- 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. Full Open API documentation: https://docs.refoss.net/open-api

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
