S4i Knowledge Hub

Explore answers to common questions about S4i products, lighting integration, smart infrastructure, and connected control systems. Whether you’re a consultant, contractor, facility manager, or simply exploring smart lighting technologies for the first time, our Knowledge Hub is designed to help you better understand how S4i solutions integrate, operate, and scale across real-world projects.

• What is S4i?

  S4i is an IoT and lighting integration company that delivers intelligent control and connectivity solutions across smart cities, buildings, homes, renewable energy, and industrial environments.

  At its core, S4i enables different lighting systems, devices, and platforms to work together through advanced integration technology. Its product ecosystem, including the Nano IB, supports lighting control, data exchange, and interoperability across a wide range of applications. By combining hardware, software, and integration expertise, S4i provides scalable solutions that simplify complex systems and enable smarter, more connected infrastructure.

• What does the Nano IB do?

  The Nano IB is an interface board designed to bridge and extend lighting and control systems.

  It includes pre-built functionality such as scene control, dimming, automation, colour sensing, and energy monitoring, while also providing an SDK for custom protocols and integrations. In practice, it is used for protocol bridging, local or wireless control, and deployment across lighting, smart city, building, and industrial projects.

• How does S4i differ from other lighting control systems?

  S4i stands out through its focus on interoperability.

  Rather than operating as a single-vendor lighting control system, S4i acts as a bridge between wired and wireless ecosystems. The Nano IB supports multiple protocols, offers both pre-built functionality and customisation via SDK, and is designed to integrate technologies such as Casambi with established wired systems like DALI and Dynalite.

  This approach reduces installation complexity, shortens commissioning time, and avoids reliance on cloud services or custom-coded solutions.

• What protocols does S4i support?

  The Nano IB supports a range of communication protocols and interfaces, including:

  • Casambi (BLE 5.0)

  • DALI

  • RS485

  • UART

  • I2C

  • Thread
  

  Additional protocol support may include:

  • DMX

  • KNX

  • IR

  • RS232

  • CAN Bus

  • GPIO

  • Wiegand (keypad/card reader)

• Can S4i integrate with existing lighting systems, or is a new system required?

  S4i solutions are designed to integrate with existing systems, so a full replacement is not required. The Nano IB is suitable for both new and retrofit installations and can bridge modern wireless control systems with existing wired infrastructure. This allows upgrades and added functionality without disrupting current systems or requiring major changes.

• Where can S4i solutions be used?

  S4i solutions are used across a wide range of applications, including:

  • Architectural lighting

  • Smart cities and public lighting

  • Smart buildings

  • Smart homes

  • Renewable energy systems

  • Industrial environments and warehouses

  • Sports fields and outdoor facilities

• How is the system installed?

  S4i systems are designed for straightforward installation and commissioning.

  The Nano IB is available in multiple enclosure options, including DIN rail mounting, making it suitable for a variety of environments.

  For projects, S4i can support the full setup process, including system design, hardware selection, configuration, and validation. For integrators, a structured commissioning approach is typically followed to ensure consistent and efficient deployment.

• Does S4i provide commissioning support?

  Yes. S4i provides commissioning and support services as part of its project delivery.

  This can include system design, on-site commissioning, validation, and remote support. In some cases, commissioning may also be carried out by partners using the S4i platform, with support provided as needed.

• Does the system require internet connectivity?

  No, S4i systems do not require internet connectivity to operate.

  Solutions can be deployed entirely offline, which is particularly important for security-sensitive environments. While remote monitoring and management can be enabled where required, this is optional and not a dependency for system operation.
