Zhaga PIR DALI Controller
Intelligent Wireless Lighting with Occupancy & Daylight Sensing
The S4i Zhaga PIR DALI Controller combines Casambi Bluetooth® Low Energy Mesh, DALI-2 lighting control, PIR occupancy sensing, and daylight harvesting into a single compact Zhaga Book 18 device.
Designed for intelligent outdoor and industrial lighting applications, it enables luminaires to automatically respond to occupancy and ambient light while providing secure wireless commissioning, scheduling and control through the Casambi ecosystem.
Supporting both DALI-2 D4i and standard DALI LED drivers, the controller delivers a complete wireless lighting solution that improves occupant comfort, reduces energy consumption and prepares lighting infrastructure for future smart city integration.
Smart Lighting That Responds Automatically
Modern lighting systems should only consume energy when and where it’s needed.
The S4i Zhaga PIR DALI Controller combines occupancy detection, daylight harvesting and wireless lighting control into a single intelligent device. Installed directly into a Zhaga socket, it enables luminaires to automatically dim, brighten or switch based on real-time environmental conditions while remaining fully configurable through the Casambi App.
Its autonomous operation reduces unnecessary energy consumption while maintaining comfort, safety and compliance across a wide range of commercial and outdoor environments.
Key Benefits
Intelligent Occupancy Detection
Integrated PIR sensing automatically detects movement, activating lighting only when areas are occupied and reducing energy usage when spaces are vacant.
Daylight Harvesting
The built-in ambient light sensor continuously measures natural light levels and adjusts artificial lighting to maintain consistent illumination while minimising energy consumption.
Wireless DALI Control
Control DALI lighting wirelessly through Casambi BLE Mesh with simple commissioning, grouping, scheduling and scene management.
Autonomous Operation
Built-in intelligence allows luminaires to respond automatically to occupancy and daylight conditions without relying on continuous network communication.
Seamless System Integration
Works with the S4i Integration Broker (IB), enabling lighting data and control to integrate with Central Management Systems (CMS), Building Management Systems (BMS) and third-party platforms.
