S4i Integration Broker (IB) is a powerful middleware software platform that enables seamless communication between otherwise incompatible building systems. Designed for smart buildings and automation environments, IB allows lighting systems, building management platforms, control systems, and IoT devices to exchange data through a unified integration layer.

With multi-platform deployment and multi-protocol connectivity, S4i Integration Broker provides a flexible, vendor-agnostic solution for integrating diverse technologies without the need for custom software development.

Key Features

Multi-platform deployment on standard PCs, industrial computers, or servers
Multi-protocol communication for building automation and IoT systems
Vendor-neutral integration architecture
Configuration-based setup (no custom coding required)
Real-time bidirectional data exchange
Scalable performance based on host hardware resources

Supported Communication Protocols

S4i Integration Broker supports multiple industry-standard protocols, including:

BACnet
MQTT
XAPI
TCP/IP
WebSocket

The protocol abstraction engine enables communication between systems that normally cannot interoperate.

Supported Ecosystems

IB enables integration across multiple automation and lighting platforms including:

Casambi wireless lighting
KNX automation
Dynalite lighting control
C-Bus lighting systems
Crestron control systems
Other IP-based automation platforms

This enables cross-vendor system interoperability within smart building environments.

Integration Capabilities

S4i Integration Broker uses a flexible mapping framework to connect system functions across platforms.

Capabilities include:

Channel-level control and monitoring
Group and scene integration
Sensor and device status monitoring
Event-based triggers and automation
Real-time command and feedback synchronization

Mappings are configured through a spreadsheet-style configuration model, enabling rapid system deployment and simplified commissioning.

Scalability

S4i Integration Broker is designed to scale from small installations to large enterprise environments.

Unlike traditional integration platforms with fixed software tiers, system capacity is determined by the host hardware configuration.

Performance scales according to:

CPU processing capability
System memory
Network bandwidth
Storage performance

This architecture allows the same IB software to operate efficiently across a wide range of deployment platforms.

Deployment Characteristics

On-premise software platform
Hardware-agnostic deployment
No internet connection required for operation
Multiple simultaneous integrations supported
Designed for scalable smart building environments

Typical Applications

Smart building integration platforms
Lighting system interoperability
BMS integration with wireless lighting
Multi-vendor building automation systems
IoT-enabled building control
