Meet Refoss R11 Smart Wi-Fi Switch
The smart home market is crowded with generic Wi-Fi switches and plugs that promise convenience but often compromise on flexibility, local control, or developer-friendly features. Enter Refoss, a brand with a clear mission: empowering advanced users, makers, and smart home enthusiasts to build smart environments without being locked into a proprietary cloud. Their debut device, the Refoss R11 Smart Wi-Fi Switch, exemplifies this approach.
Unlike most consumer-grade switches, the R11 provides complete JSON-RPC 2.0 support via HTTP, webhook, and MQTT, giving developers and tinkerers full control. Whether you want to create custom automations, integrate with third-party services, or build your own smart home dashboard, the open API opens the door to endless possibilities. The R11 doesn’t just turn devices on or off — it helps you understand their energy footprint. Real-time energy monitoring, with hour-level export and cloud-based statistics, allows for smart energy management and cost tracking, perfect for eco-conscious households or technical enthusiasts.
For Home Assistant users, the integration is seamless. You can easily add the R11 to your Home Assistant setup, enabling advanced automations, custom dashboards, and real-time monitoring without relying on third-party clouds. Designed to fit behind standard wall switches, the R11 installs without altering existing wiring or aesthetics. This makes it ideal for both new builds and retrofitting older homes, ensuring your smart home upgrade doesn’t require a full renovation.
Safety is baked in. With overvoltage, overcurrent, and overpower protection, the R11 is built to operate securely under a variety of electrical conditions, giving peace of mind alongside smart functionality. As with most advanced smart switches, a neutral wire (typically blue) is required for safe and effective operation. Proper installation ensures reliable performance and safety compliance.
Installation is straightforward for anyone comfortable with standard electrical wiring. Once connected to the neutral and live wires, the R11 can be paired with your Wi-Fi network. From there, either use the Refoss app or leverage the open API for advanced configurations. Home Assistant users will appreciate the instant detection and control options.
The Refoss R11 Smart Wi-Fi Switch is a standout option for anyone serious about smart home automation. While mainstream alternatives like Meross or TP-Link focus on simplicity and cloud-centric convenience, the R11 gives you control, transparency, and flexibility — the tools that advanced users crave. If you’re building a custom smart home setup or simply want a future-proof, developer-friendly switch, the Refoss R11 is an excellent choice.
Refoss R11 Smart Wi-Fi Switch Main Features
– Fully Open API Access: Supports JSON-RPC 2.0 via HTTP, webhook, and MQTT for advanced custom integrations.
– Energy Monitoring: Track energy consumption in real-time with hour-level export and cloud-based statistics.
– Home Assistant Integration: Seamlessly integrate with Home Assistant for enhanced automation and monitoring.
– Compact Retrofit-Friendly: Easily fits behind standard wall switches without altering existing wiring or aesthetics.
– Safety Design: Built-in overvoltage, overcurrent, and overpower protection for secure operation.
– Neutral Wire Required: Ensure safe and effective operation by connecting the switch to a neutral wire (typically blue) in your existing setup.
Refoss R11 Smart Wi-Fi Switch can be useful in a variety of real-life scenarios:
– Invisible Smart Socket or Light Switch. Hide intelligence behind your existing outlets or switches without disrupting your home’s aesthetics. The R11 mounts flush behind the wall, making your setup smart while keeping design intact.
– Energy Monitoring & Automation. Track real-time power usage via the R11 and, for instance, automatically cut power once a device finishes its job (like a washer completing a cycle), saving energy and reducing standby draw.
– Home Assistant–Driven Device Control. Seamlessly integrate the R11 with Home Assistant for custom automations—whether that’s scheduling lights, coordinating fan operation, or linking appliances to changing conditions.
– Appliance Safety Cut-Off. Automatically turn off potentially hazardous appliances (e.g., irons or space heaters) if they remain on too long, preventing accidents or overheating.
– Ambient TV Lighting Automation. Connect the TV to an energy-measuring smart plug and configure Home Assistant to light up ambient backlighting via the R11 whenever the TV powers on—and switch it off once you’re done.
– Quiet Fan Activation in Heating Mode. Use the R11 to trigger a fan or circulation pump when heating devices (like infrared panels) kick on—boosting efficiency and comfort automatically.
– Automatic Light Shut-Off for Idle Devices. Prevent “lights left on” inefficiency by configuring the R11 to deactivate lights if they draw very low power over an extended time—e.g., forgetting to turn off bedside lamps.
– Smart Garage or Gate Integration. Though not an exact dry-contact, similar relay setups are used for garage or gate automation. The R11 can fit into such systems with some integration—whether via Home Assistant or custom API setups.
– DIY Automation for Any Dumb Remote. With a bit of wiring and coding, the R11 can simulate button presses (like on RF remotes), turning otherwise non-smart remotes smart by triggering commands directly.
– Comprehensive Local Automation (Cloudless & Secure). Thanks to its Open API supporting JSON-RPC 2.0, webhook, and MQTT, you can build fully local, cloud-free automation systems—great for privacy-focused setups.
Refoss mobile application
Setting up the Refoss R11 Smart Wi-Fi Switch with the Refoss app was straightforward and surprisingly quick. Once wired in, the app instantly recognized the device and gave me full control over it from my phone. I could turn the connected appliance on or off with just a tap, whether I was at home or away. That simple ability already gave me a sense of convenience and reassurance.
What I liked most was the scheduling feature. I set up a daily plan so my desk lamp switches on automatically in the evening and turns off at night, without me having to remember. It feels natural now—like the lamp has its own routine. The app makes creating these schedules very intuitive, and once saved, they run reliably in the background.
Voice control added another layer of convenience. After linking the app to my Google Assistant, I could simply say, “Hey Google, turn on the lamp”, and the switch responded instantly. It’s the kind of little detail that makes life feel easier, especially when my hands are full.
I also appreciate being able to check the status of the switch remotely. More than once, I’ve left home wondering if I forgot to turn something off. Now I just open the Refoss app, see the device status, and toggle it if needed. That small feature brings a lot of peace of mind.
Overall, the Refoss app feels clean, responsive, and reliable. Paired with the R11 Smart Relay Switch, it gives me effortless control over my devices, whether I’m automating lights, managing appliances, or just checking in while away. While the app could improve with more advanced scene customization, for everyday use it works beautifully and does exactly what I need: simple, reliable smart home control at my fingertips.
You can download Refoss application latest version for free from Google Play Store or from App Store.
