All about "Fusion" Series

The SONOFF Fusion Series provides a practical and integrated wall switch solution for smart home retrofitting and installation. It elegantly combines the proven electronics of MINI Extreme modules with a new, modular system of slim enclosures and frames. Designed to address common installation constraints—such as shallow European back boxes - the series enables a complete and aesthetic upgrade for all switch types in a home, from lighting and sockets to curtains and dimmers. With support for both Zigbee and Matter-over-WiFi, it ensures broad compatibility with major smart home ecosystems, offering a unified and flexible approach to whole-home automation for both retrofit and new-build projects.

Introduction & Genesis

The SONOFF Fusion Series was born from a clear and practical need observed in the smart home retrofit market, particularly in regions with specific architectural standards like Europe. Its genesis addresses two core challenges:

1. Overcoming Physical Constraints: A significant hurdle in retrofitting smart switches, especially in many European homes, is the prevalence of shallow-depth switch back boxes (junction boxes). The popular and powerful SONOFF MINI Extreme modules, when paired with a user’s existing traditional switch, could often be too deep to fit comfortably within these constrained spaces, leading to difficult installations or compromised finishes.

2. Providing a Complete, Cohesive Solution: Homeowners and installers needed more than just a module; they demanded a fully integrated, aesthetically uniform system to upgrade every type of switch in a home- from lights and sockets to curtains and dimmers - without the visual clutter of mismatching products.

The Fusion Series is the direct answer to these challenges. The name “Fusion” signifies the elegant unification of the proven, robust internals of the MINI Extreme modules with a newly designed, modular family of slim-profile enclosures and frames. This innovative fusion transforms a DIY component into a refined, retail-ready product line.

It provides a complete, scalable solution that is equally ideal for modernizing older properties ("retrofit") and for streamlined installations in new construction or renovation projects ("new-build"). By ensuring compatibility with standard European wall boxes and offering unparalleled mix-and-match flexibility, the Fusion Series provides an elegant and professional solution to the shallow back box challenge, enabling a seamlessly integrated smart upgrade for any home.

Design Philosophy & Core Principles

The design of the Fusion Series is guided by three fundamental principles:
● Modularity & Flexibility: At its heart, Fusion is a modular solution. Users are not limited to pre-defined switch configurations. Instead, they can combine different switch types within standard wall boxes, creating tailored control setups that match their specific needs.
● Unified Aesthetic: Every product in the series shares a consistent design language—clean lines, subtle curves, and a premium finish. This ensures that whether you're installing a simple socket or a multi-gang switch panel, the result is a cohesive and stylish look that enhances any interior decor.
● Universal Compatibility & Ease of Installation: The series is meticulously engineered to fit standard European two-gang junction boxes. The modular frames and enclosures allow for easy mixing and matching, making it possible to intelligently automate every switch in a home, regardless of its original function, while achieving a flawless, integrated appearance.

Technical Highlights & Protocol Strategy

• Dual-Protocol Strategy: By offering identical functionality in both Zigbee 3.0 and Matter-over-WiFi versions, the Fusion Series future-proofs installations. Users can choose the protocol that best fits their existing smart home hub, whether it's Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, or a dedicated Zigbee coordinator, ensuring broad ecosystem compatibility.
• Broad Compatibility: The series is designed for global use, with a focus on European electrical standards. Products like the Orb Socket are specifically designed as Type E/F wall sockets.
• Advanced Features: Depending on the model, features include energy monitoring, no-neutral-wire installation (for specific switches), and support for complex automation rules within the eWeLink ecosystem and partner platforms.
  
  
  

Installation Flexibility

This modularity is the cornerstone of the series and builds upon a familiar European installation standard. The traditional physical switch landscape in Europe is already modular, allowing homeowners to combine different switch functions (e.g., a light switch, a socket, a shutter control) within a standard multi-gang wall box to create a customized control panel.

The SONOFF Fusion Series seamlessly extends this established modularity into the smart era. It preserves the flexibility users expect, while intelligently upgrading every function. Within a standard two-gang wall box (junction box), users are not limited to installing two identical smart switches. The system allows for any logical combination of different smart switch types—such as a light switch paired with a roller shutter controller, or a dimmer next to a smart socket—to be installed side-by-side. This creates a tailored smart control point that perfectly matches the room's actual needs, maintaining the customizability of traditional setups but with enhanced, intelligent control.

For example:

• A dual-gang box can combine a single-gang light switch with a roller shutter switch, controlling both room lighting and window shades.
• Another box could house a dimmer switch alongside a smart socket, perfect for a bedside table setup.
• Virtually any combination of different load controllers can be accommodated to meet specific scenarios.

A Whole-Home Smart Solution: This capability ensures that an entire house can be upgraded to smart control using an aesthetically consistent product family. The modular enclosures guarantee a perfect, gap-free fit for any combination, delivering a professional and integrated finish that honors the flexible spirit of European electrical installations while propelling them into the future.
