For Roldy Cueto Cabrera, lighting isn’t just a job—it’s a calling shaped by resilience, adaptability, and a passion for creating beautiful, functional spaces.

Born and raised in Havana, Cuba, Roldy was once a member of the national cycling team, an experience that instilled in him the discipline and determination he brings to every project.

“Obstacles never stop me,” he says. “They might slow me down, but they only make me stronger.”

After earning a degree in Electronic Engineering at the University of Havana, Roldy was introduced to the world of light through Paolo Targetti and the wider Targetti family—an experience that sparked a lifelong love for lighting design and control.

Now based in Switzerland, Roldy runs RNHC Services, where he specializes in commissioning Casambi and Adquio systems for residential, commercial, and heritage projects.

“Casambi and Adquio together offer complete freedom,” he explains. “No limits, just flexibility. I’m here to help you bring your vision to life with all my passion and knowledge.”

How to Make a Project Work

For Roldy, the key to a successful lighting control installation is simple:
“You need the right amount of light at the right moment. That’s how you truly benefit from the system.”

He’s drawn to Casambi’s flexibility and intuitive interface, which makes even the most complex challenges manageable. “Signal loss has never stopped me from finishing a project,” he adds. “Casambi just works—it’s a system without barriers.”

That said, some projects are more complex than others. Sensor integration and conditional logic can require creative thinking. “But there’s always a way,” Roldy says. “We find it.”

Project Highlights: History, Holidays, and High Expectations

One of Roldy’s proudest projects is the Abbaye de Saint-Maurice—a historic site with thick stone walls and demanding lighting needs.

The system combined sensors, timers, and scene controls—all enabled by the flexibility of Casambi and a close collaboration with partner ADQUIO.

Another standout: the Christmas decorations in Lausanne. The lighting spanned three separate streets and had to operate seamlessly despite frequent power cuts.

Using LigaAir antennas, timer backups, and precise scene programming, Roldy delivered a solution that impressed the city and highlighted the power of expert commissioning.

A System Built on Trust and Tools

To bring ideas to life, Roldy relies on the Casambi Demo Cube, a vital tool that helps him prototype scenes, troubleshoot setups, and demonstrate possibilities on-site. It’s this combination of technical knowledge, creative problem-solving, and hands-on tools that defines his approach.

And it’s all driven by passion.

“I wear a Casambi t-shirt every day. That says everything about how proud I am to be part of this world.”

The Swiss Market: Opportunities and Challenges

In Switzerland, demand for wireless and smart lighting is growing fast. But Roldy sees challenges too—especially around how the role of the commissioning engineer is perceived and valued.

“Our work needs to be protected,” he explains. “When clients bypass us to buy products themselves, it weakens the value of commissioning and risks Casambi’s reputation. But when we’re trusted and involved, everyone benefits.”

He also hopes that architects and lighting designers will deepen their understanding of what commissioning really involves.

“They’re essential collaborators—but they still need to see the importance of our technical expertise.”

Beyond Lighting: A Photographer at Heart

When he’s not designing or commissioning lighting systems, Roldy explores his other creative passion: photography.

He’s an official photographer for the Swiss Swimming Federation, and his work can be found at roldy.com.

There’s a lot of noise in the smart lighting world right now. Bold claims. Flashy demos. Promises of revolution. But beneath all the marketing buzz, how much is really scalable, interoperable, or future-ready?

I’ve been in this business a long time, and I’ve seen the patterns. Dozens of companies have tried to build wireless lighting control solutions. The formula’s almost always the same: buy a radio chip, spin up an app, slap together some modular hardware, and launch a website.

They look promising at first. But they all hit the same wall.

Each ends up boxed into a narrow slice of the market:

• One lighting application – maybe warehouse, residential, or office
• One geography – Germany, the UK, the U.S., Asia
• One go-to-market channel

These are closed, proprietary ecosystems built around a handful of SKUs – maybe 20 at most – customized for a single use case and local electrical code. It works, for a while. But when the ambition grows – to support real projects, scale globally, or adapt to complex customer needs – these companies collapse under the weight of their own complexity.

Casambi is doing something very different.

We’ve taken the opposite approach. We’ve built an open ecosystem – with more than 2,000 Casambi-enabled SKUs that are fully interoperable. Our platform is used in every lighting application you can think of: architectural, retail, hospitality, residential, street lighting, and beyond. It works in over 150 countries. And it’s available through trusted, local sales channels.

This is not a tech experiment or a closed club. It’s a living, growing network. Our partners – more than 300 Casambi-Ready companies – don’t just sell products. They succeed because they’re part of something bigger.

The question isn’t whether BLE lighting control works. It does.

The real question is this:
How many BLE control platforms can your sales team actually learn, support, and explain to customers?

If you’re a luminaire manufacturer trying to juggle multiple BLE solutions across markets, verticals, and geographies – you’re probably already feeling the pain. There’s a better way.

With Casambi, you get one platform. One global ecosystem. Every application. Everywhere.

This is why we call Casambi the Operating System of Lighting. It’s smart software. Clean hardware. Easy installation. And it just works – whether you’re lighting a museum in Paris or a logistics center in Tokyo.

Let’s cut through the noise. The future of lighting control is open, scalable, and built on collaboration.

“The real innovation isn’t adding features – it’s removing friction.”
– Mark McClear, CEO, Casambi

JUNG, a family-run business founded in 1912, is renowned for its commitment to precision, quality, and timeless design made in Germany. From classic plastic to elegant glass and metal, JUNG’s diverse switch ranges combine aesthetic appeal with intuitive functionality, designed to match every architectural concept and user need. We sat down with Deniz Turgut, Head of Marketing at JUNG, to learn more about how the company merges heritage and innovation—and how the partnership with Casambi is helping redefine the future of lighting control.

Design with Depth, Shaped by Real Needs

“JUNG switches are all about timeless design, precise workmanship, and high quality,” Deniz begins. “We make sure that design and functionality go hand in hand—operation should be intuitive, and the technology reliable.”

JUNG’s user-centric approach plays a central role in its product development. “We develop our products in close dialogue with architects, planners, and users,” Deniz explains. “More and more, people want flexible, sustainable solutions that fit into their personal and professional environments.” This dialogue results in smart switch ranges that are not only beautifully crafted, but also adaptable to varied and evolving demands.

A Flexible Future: Open Systems and Wireless Control

JUNG places a strong emphasis on interoperability to ensure its solutions are future-ready. “Whatever the control standard or system, our goal is to offer customers solutions that integrate smoothly into their projects,” Deniz says. This makes JUNG switches a reliable and scalable choice for a wide range of applications, from homes to commercial buildings.

That philosophy naturally led to the collaboration with Casambi. “Casambi’s Bluetooth-based solution complements our switch portfolio perfectly,” Deniz explains. “It allows us to offer battery-free, wireless controls that don’t compromise on design.” Today, JUNG offers more than 150 Casambi-compatible wall-mounted switches and sockets—bringing smart functionality to even the most traditional settings without the need for rewiring or battery changes.

Lighting Control That Feels Just Right

The integration with Casambi transforms JUNG’s switches into intelligent interfaces. “It opens up completely new possibilities, from private homes to hotels and restaurants,” Deniz notes. “Users can control, dim, and automate lighting using app-based scenes while still enjoying the tactile feedback of a beautifully crafted switch.”

The response from the market has been enthusiastic. “We get very positive feedback—especially from architects and planners working on renovations or heritage buildings. They appreciate the easy installation and design flexibility,” Deniz says. “And users love not having to worry about replacing batteries.”

Looking ahead, JUNG remains committed to pushing innovation. The company is investing in smarter, more sustainable products, exploring new materials, design variants, and advanced features that enhance everyday living. “Wall controls will continue to play an important role,” Deniz emphasizes. “It’s all about combining classic usability with digital possibilities—and that’s exactly what we’re doing.”

From the outside, Casambi appears as a bright, shining example of modern lighting technology—elegant, wireless, and powerful. But today, we’re going to delve a little deeper. It’s time to pop the bonnet and see what’s really under the hood.

At its core, Casambi is a software company. Our software is the engine behind a lighting revolution that’s transforming how the world experiences and controls light. But software alone doesn’t illuminate buildings or bring architectural visions to life. It needs hardware to run on—and that’s where the real story begins.

When we look under the hood, we see the true engine powering everything: our global network of OEMs—Original Equipment Manufacturers. In Casambi-speak, these are our Ecosystem Partners.

Casambi’s Real Power: Its Ecosystem

Casambi is literally powered by its customers. Our Ecosystem Partners are lighting manufacturers across the world who embed Casambi technology into their luminaires, sensors, drivers, and switches. We collaborate closely with them to ensure that every Casambi-enabled product delivers the performance and reliability that lighting professionals and end users expect.

This partnership approach is what makes Casambi different. It’s not a closed, top-down system. Instead, it’s an open, thriving ecosystem of experts building products around a common wireless platform.

Why Radio Matters

All Casambi networks are wireless, and radio performance is the invisible force that makes them work. For a Casambi installation to perform flawlessly, the wireless signals must be strong, stable, and predictable—across diverse environments, building materials, and use cases.

As the number of Casambi products and partners grew, we began to see variability in wireless performance. While most partners were dedicated and diligent, not all products met the standards required for optimal radio reliability.

Raising the Bar on Radio Quality

To address this, the Ecosystem team launched a program—a comprehensive initiative offering free technical advice to Ecosystem Partners on how to design products with high-quality radio performance in mind.

But guidance alone wasn’t enough. We needed a way to measure outcomes. So we built a dedicated test lab in Finland where every new Casambi-enabled product from our partners is rigorously tested for radio quality. Our lab engineers evaluate the performance of each product and send back a detailed Radio Test Report.

Sometimes the product passes with flying colors. Sometimes it doesn’t. But in either case, the report gives manufacturers clear, actionable insights—whether it’s antenna placement, PCB layout, or shielding issues—that help them improve and iterate.

No Compromises

Since introducing this program, we’ve made one thing clear: no product is listed on the Casambi website unless it passes our radio quality standards. This policy has been in place for over two years and has significantly raised the bar for wireless reliability across the board.

The result? A stronger, more consistent user experience. Installers can work with confidence. End users get seamless, stable performance. And our partners have a clear, supportive pathway to making great wireless lighting products.

The Road Ahead

The Casambi Ecosystem is always evolving. With each new product tested, with each partner supported, we strengthen the foundation of the wireless lighting revolution. Because when you lift the bonnet on Casambi, you don’t just find technology—you find people, partnerships, and a relentless focus on quality.

As the world of lighting continues to evolve, so too does the need for smarter, more adaptable systems that meet the needs of diverse environments. At Casambi, we’ve always been committed to pushing the boundaries of wireless lighting control, and today, we want to dive into an exciting advancement in the world of smart lighting: the Zhaga Book 20.

What is Zhaga Book 20?

The Zhaga Book 20 standard is a key development that sets the groundwork for smart interfaces between indoor luminaires and sensing/communication modules. The standard is designed to enhance the adaptability of luminaires, enabling them to communicate wirelessly and interact with the broader smart building ecosystem. In essence, it provides a flexible and scalable approach to integrating wireless technology with lighting, solving many of the challenges traditionally faced in this space.

For those interested in a deeper technical dive, you can explore the Zhaga Book 20 specification in detail here.

The OEM Advantage: One Luminaire, Multiple Options

One of the most significant benefits of Zhaga Book 20 for Original Equipment Manufacturers (OEMs) is the ability to design one luminaire that can adapt to multiple control options. In the past, lighting fixtures often had to be designed specifically to accommodate different control systems, creating inefficiencies and limiting the possibilities for customization.

With Zhaga Book 20, however, the intelligence is housed in the node itself, meaning that the same luminaire can be used with different smart control solutions. This not only simplifies the design process but also enables more flexibility for manufacturers and end-users alike. Whether it’s for dimming, light scene control, or integrating with building management systems, this versatility makes it easier to create scalable and adaptable lighting networks.

Solving Wireless Communication Challenges: Metal-Housed Luminaires

A challenge that has long plagued wireless lighting systems, particularly in the Nordics, DACH, and Benelux regions, is the interference caused by metal-housed luminaires. These types of luminaires, commonly used in industrial and officesettings, can significantly disrupt wireless signals, making it difficult to implement reliable wireless control.

Zhaga Book 20 addresses this issue by enabling efficient wireless communication in these applications. The ability to seamlessly integrate wireless control in metal-housed luminaires is a huge leap forward, particularly for regions and industries that rely on such products.

Expanding Wireless Solutions to New Segments

With the launch of Zhaga Book 20, wireless lighting control is no longer limited to traditional applications. The standard opens up a host of new possibilities for product segments that have traditionally been more challenging to integrate with wireless systems, such as metal profiles, ceiling-mounted fixtures, and large-scale industrial lighting systems.

This evolution is critical for advancing smart building technology. Industries like manufacturing, logistics, and large commercial spaces can now embrace wireless lighting solutions that are simple to implement and scale as their needs grow. For the first time, products that were previously constrained by complex wiring or difficult installation conditions can be part of the wireless revolution.

Data-Driven Lighting: The Role of D4i Drivers

As lighting systems become more intelligent, data will increasingly drive decisions. The D4i drivers that power the Zhaga nodes are at the heart of this shift. These drivers provide the essential communication interface between luminaires and other building systems, enabling data exchange and control. This opens up new possibilities for optimizing lighting performance based on real-time environmental data, occupancy patterns, and energy consumption metrics.

The ability to leverage data for more efficient lighting systems is key to the future of smart buildings. It not only enhances energy efficiency but also enables more personalized and responsive lighting environments that improve user experience and overall system performance.

Conclusion: The Future of Wireless Lighting

The introduction of Zhaga Book 20 is a game-changer for the lighting industry, offering significant benefits for OEMs, integrators, and end-users alike. By providing a standardized interface for intelligent, wireless luminaires, Zhaga Book 20 simplifies the deployment of smart lighting solutions across a range of environments and use cases.

At Casambi, we’re excited about the opportunities this standard creates and are committed to helping our partners leverage the power of wireless lighting. As the industry continues to evolve, we believe that Zhaga Book 20 will play a pivotal role in shaping the future of smart, data-driven lighting solutions.

As we continue to explore the possibilities of this new technology, we encourage our ecosystem partners to embrace these innovations and take full advantage of the flexibility and scalability offered by Zhaga Book 20.

Stay tuned, as we are excited to see how this technology will unlock new opportunities for smart lighting in the years to come.

Imagine if every purchase you made forced you into using the same brand for everything. Sounds limiting? Unfortunately, that’s exactly what happens when businesses or individuals adopt closed, proprietary systems. Let’s explore this concept a bit deeper.

Locked-In Choices: Three Everyday Examples

1. Your Wardrobe

Picture buying a t-shirt, and from that moment on, every article of clothing you wear—socks, shoes, jackets—must come from the same brand. Not because you want to, but because mixing brands would make your outfit “incompatible.” You lose the freedom to express your style, and worse, you’re stuck with the same design language, materials, and even price point.

2. Painting Your Home

Imagine painting one wall in your home using a specific brand of white paint. Suddenly, you’re locked into using that exact brand for all future painting projects—other walls, ceilings, touch-ups—because no other paint brand will “blend” properly. This not only limits your options but likely forces you to pay a premium over time, while sacrificing variety in finishes, tones, or price ranges.

3. Fuel Stations

Imagine if you could only refuel your car at a specific brand of gas stations. You’d be limited to where you could travel and forced to pay higher prices just because that brand owns the only compatible stations in your area. An open system, where all fuel stations support multiple car brands, gives you flexibility and freedom to choose where to fuel up.

Proprietary Systems: The Hidden Cost of Control

Proprietary systems are designed to create vendor lock-in, where one company controls the entire ecosystem—hardware, software, and accessories. While this may ensure a certain level of integration, it stifles innovation and limits customer choice. As a result, businesses and end-users are left paying higher prices and working with fewer options.

The Casambi Approach: An Open Ecosystem Built for Flexibility

At Casambi, we take a different path. Our solution blends a solid, reliable core technology with an open ecosystem. We welcome manufacturers from all over the world to build Casambi-compatible products. This model encourages innovation and competition, while guaranteeing interoperability and seamless user experience.

Why an Open Ecosystem Makes a Difference

Faster Innovation

When manufacturers can build freely on a strong technological foundation, new ideas and products reach the market faster. There’s no waiting for a single company or slow-moving standards bodies to decide what’s next. Instead, creativity flourishes.

Greater Variety and Availability

An open ecosystem leads to hundreds of compatible products, giving customers the power to choose based on specific needs, design preferences, or budget. Whether it’s luminaires, sensors, or switches, there’s a solution at every level—from cost-effective to premium.

Healthy Competition Ensures Fair Pricing

When multiple manufacturers compete within the same ecosystem, it keeps prices competitive and value-driven. There’s no monopoly dictating costs, and customers benefit from a dynamic marketplace.

Lighting Should Be as Open as Your Lifestyle

In the same way you expect freedom to choose your clothing brands, home paint colors, or gas stations, you deserve that flexibility in your lighting systems. Open ecosystems like Casambi put power back in the hands of the customer—where it belongs.
