EBELONG ERC22-KNX: Bridging Wireless Kinetic Innovation with the KNX Standard

KNX is the world’s leading open standard for building automation, recognized across more than 190 countries and supported by thousands of certified products. Its strength lies in its stability, reliability, and interoperability. By using a single bus system, KNX enables seamless control of lighting, HVAC, security, shading, and many other building functions. System integrators value KNX because it is vendor-independent, future-proof, and backed by decades of global adoption. Every device certified by the KNX Association, which gives engineers peace of mind when designing complex projects.

However, traditional KNX systems also come with challenges: wiring is often extensive, installation can be time-consuming, and flexibility in retrofitting older buildings is limited. Each switch or actuator must be connected to the KNX bus, which raises both labor costs and disruption during installation. In a market that increasingly values speed, flexibility, and sustainability, integrators and property owners are searching for solutions that combine the robustness of KNX with the agility of wireless technologies. This is where EBELONG brings new value—merging its proprietary wireless kinetic switch technology with the KNX ecosystem, creating a powerful synergy that enhances both.

Wireless Kinetic Technology Meets KNX

EBELONG has pioneered wireles kinetic switches, which harvest energy from the physical act of pressing a button. This tiny burst of kinetic energy generates enough power to transmit a reliable RF signal, eliminating the need for batteries or wiring. The benefits are immediate: no maintenance, no battery replacements, and complete freedom of placement. For years, this technology has proven itself in residential, hospitality, and commercial projects, helping reduce costs and increase design flexibility.

By integrating this wireless kinetic technology into the KNX world, EBELONG introduces the ERC22-KNX Wireless Coupler. This device acts as a translator between EBELONG’s RF protocol and the KNX bus. When a user presses a kinetic switch, the RF signal is received by the coupler, which then converts it into a KNX telegram, fully compliant with KNX standards and configurable.This innovation means that KNX installations can now benefit from battery-free wireless switches, expanding the possibilities for both new builds and retrofits. It is the perfect balance of KNX’s structured reliability and EBELONG’s wireless simplicity, giving integrators new tools to address client needs.

Product Advantages and Features

The ERC22-KNX Wireless Coupler offers a wide range of features designed to simplify installation and enhance flexibility:

• Battery-Free and Maintenance-Free: Unlike wireless sensors or switches that rely on batteries, EBELONG’s kinetic switches never need replacements. This dramatically reduces operating costs and ensures uninterrupted performance for years.
• Scalable Multi-Control: Each coupler supports up to 20 wireless device channels, allowing integrators to deploy multi-point control scenarios with ease. Imagine one switch controlling multiple circuits, or multiple switches controlling the same load—flexibility is built-in.
• Compact Design: With dimensions of just 44 × 44 × 22 mm, the coupler fits neatly into standard 86-type junction boxes. This makes it especially suitable for renovation projects where wall space is limited and aesthetics are critical.
• Certified Reliability: The product strictly follows KNX standards, and guaranteeing stable operation. Integrators can configure devices with confidence, knowing that the system adheres to the globally recognized KNX certification process.
• Strong Wireless Performance: Operating at 433 MHz with a sensitivity of –110 dBm, the system provides an indoor communication range of up to 80 meters, sufficient for most building environments.
• Longevity and Safety: Built from flame-retardant PC materials and designed for a service life of over 10 years, the product also ensures user safety with clear installation guidelines and IP20 protection when installed in wall boxes.

This product is designed to combine ease of installation, long-term reliability, and scalable flexibility, addressing pain points in traditional KNX deployments.

Operation and Configuration

Operating the ERC22-KNX system is straightforward and user-friendly. From a user perspective, it is as simple as pressing a button: the kinetic switch generates power, transmits an RF signal, and the KNX coupler converts that into an action—such as turning on lights, dimming a circuit, or controlling curtains.

For system integrators, the process is equally efficient. The coupler is powered directly by the KNX bus (21–30 V DC), requiring no additional power supply. Once connected, the device can assign addresses, define group objects, and configure functions just as they would with any KNX device. The coupler supports up to 20 wireless kinetic switches and 20 RF controllers, allowing complex control logic to be established. For example, a single coupler can manage inputs from multiple switches spread across a large conference room or hotel suite, and translate them into KNX actions with precision.

The installation process is also simplified: the coupler can be mounted directly into standard switch boxes or equipment cavities, preserving the original wiring structure. This makes it particularly effective for retrofit projects where minimizing disruption is critical. In addition, EBELONG provides clear wiring diagrams and polarity guidance, ensuring that electricians can complete the installation safely and quickly. With plug-and-play wireless devices on one side, and the robustness of KNX integration on the other, the ERC22-KNX offers one of the simplest yet most powerful setups in the market.

Application Scenarios

The versatility of the ERC22-KNX system means it can be applied across a wide range of sectors:

• Residential Homes: Homeowners can enjoy the flexibility of placing switches anywhere—on walls, glass, or furniture—without the hassle of rewiring. It’s ideal for modern apartments, villas, and smart home upgrades where aesthetics and convenience matter.
• Hospitality & Hotels: In hotels, guest rooms can be equipped with flexible lighting and curtain controls. Maintenance is minimized since no batteries are needed, and installation is faster, reducing downtime for room renovations.
• Commercial Buildings & Offices: In dynamic office environments, layouts change frequently. Wireless kinetic switches allow facility managers to reconfigure lighting and shading controls without calling in electricians or disrupting operations.
• Healthcare & Public Facilities: Hospitals and clinics benefit from non-invasive installations that maintain hygiene standards and avoid dust or noise during retrofits. Wireless switches can be placed at optimal locations for accessibility and convenience.
• Heritage & Renovation Projects: In older or historically protected buildings, rewiring can be costly or even prohibited. The ERC22-KNX provides a non-destructive alternative, bringing smart control to spaces where traditional wiring is impractical.

By bridging KNX with EBELONG’s wireless kinetic technology, the system delivers fast deployment, flexible design, and long-term sustainability, making it a compelling choice for architects, system integrators, and property developers alike.

The EBELONG ERC22-KNX Wireless Coupler is more than just a product—it’s a vision of what building automation can become. By merging the robust, certified backbone of KNX with the simplicity and sustainability of wireless kinetic switches, EBELONG offers a solution that reduces installation complexity, cuts maintenance costs, and opens new possibilities for smart building design.

For system integrators, this means faster projects and greater flexibility. For property owners, it means lower operational costs and future-proof investment. And for end users, it means smarter, more convenient living spaces with intuitive controls that work every time—without the burden of wiring or batteries.

In a world where sustainability, efficiency, and user experience are top priorities, the ERC22-KNX stands as a future-proof innovation, ready to transform how buildings are designed, upgraded, and experienced.
