If you want to modernize your home and turn it into a smart house, you probably face the same dilemma: smart plugs take up too much space and ruin the room's aesthetics, while completely replacing existing outlets can be costly.

Sonoff comes with the ideal solution through the new WS01TPF-E model, a smart relay specifically designed to be mounted hidden away, directly inside the wall box behind your existing classic outlet or switch. It is part of the new generation of Matter-over-Wi-Fi devices, delivering raw power and universal compatibility.

🏗️ Robust Hardware: Hidden Power Inside the Wall 🤓

Despite its extremely compact dimensions, engineered to fit inside standard European wall boxes (Type E), the Sonoff WS01TPF-E makes no compromises when it comes to electrical performance:

• Load Capacity: Supports a rated current of up to 16A, making it capable of handling heavy-duty consumers (appliances, space heaters, washing machines).

• Maximum Power: Can safely switch a resistive load of up to 3840W.

• Active Safety: The casing is manufactured from high-quality flame-retardant polycarbonate (PC), ensuring excellent thermal and electrical protection inside the wall.

• Hybrid Control: Allows you to retain the functionality of your existing mechanical switch or outlet, acting as an invisible brain in the background.

🧠 Universal Integration via the Matter Standard 🏠🌐

The greatest technological advantage of the WS01TPF-E model is its Matter certification. This means the device eliminates barriers between brands and apps, communicating directly within your local network:

• Multi-Ecosystem Compatibility: Integrates natively and simultaneously with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and Home Assistant.

• Instant Configuration: Adding it to the system is done by simply scanning the Matter QR code directly from your favorite app, without the need for intermediate accounts or third-party clouds.

⚡ Smart Monitoring and Advanced Protection

Once installed in your electrical grid, the WS01TPF-E becomes a true energy administrator for your electronics:

• Energy Monitoring: Track power consumption in real-time and generate useful statistics to understand exactly which appliances are inflating your electricity bill.

• Overload Protection: The module constantly monitors the current and automatically shuts off the power supply if it detects dangerous values that could compromise the installation.

• Scenes and Automations: Program timers, operating schedules, or smart scenes—such as automatically turning off the water heater when you leave home.

✅ Technical Verdict: The Invisible Upgrade You Need

The Sonoff WS01TPF-E is the definition of efficiency in the in-wall relay segment. It successfully brings the Matter standard and 16A energy monitoring into a format completely hidden from view. It is the perfect solution for those who want a smart home but wish to maintain the clean design of their original finishes and outlets.

Technical Recommendation: As with any 16A relay, for complete safety, ensure that the circuit in that specific wall box is protected upstream in the main electrical panel by an appropriate circuit breaker (MCB).
