Smart Automation Built for Residential Scale

Residential towers and apartment complexes present a unique automation challenge: hundreds of independent units that each need individual comfort control, yet share common infrastructure that must be managed centrally. Smart Group G4 solves this with the sBUSPro bus topology — a single wired backbone that connects every unit, every corridor, every car park, and every plant room under one management platform.

Unlike hotel GRMS systems that require per-room controllers at premium cost, the G4 mass-residential architecture uses shared DIN-rail controllers per floor or per riser, dramatically reducing hardware cost per unit while maintaining full individual control. Developers in the Middle East, South Asia, and Southeast Asia have deployed G4 across residential towers ranging from 80 to 1,200 units.

Core Capabilities

Per-Unit Lighting Control

Affordable smart lighting for every apartment unit — dimmers, scenes, and automation without the luxury price tag. Residents control via wall panels, smartphone app, or voice assistant. Scenes include Welcome, Relax, Sleep, and Away.

Central HVAC Management

Centralised HVAC management with per-unit control, energy metering, and automatic setback for unoccupied units. Integrates with VRF, chiller, and split-system air conditioning via Modbus or BACnet.

Building Security

Video intercom, access control, and perimeter security for the entire building — managed from a central security station. Integrates with CCTV, barrier gates, and biometric readers.

Energy Sub-Metering

Per-unit energy sub-metering for accurate billing, energy reporting, and identification of high-consumption units. Supports utility billing export and DEWA/SEWA/FEWA-compatible reporting formats.

Common Area Automation

Automated lighting, HVAC, and access control for lobbies, corridors, car parks, gyms, and all common areas. Occupancy-based control reduces common-area energy consumption by 30–50%.

Scalable Architecture

The sBUSPro bus topology scales from a single building to an entire residential complex — with centralised management. One software platform manages all buildings, all floors, all units.

Deployment Scenarios

High-Rise Residential Towers

G4 is deployed in towers of 20–60 floors across the GCC and South Asia. The sBUSPro backbone runs vertically through the riser, with floor-level controllers serving 4–8 units each. Management software gives the building operator a live floor-plan view of every unit's status.

Affordable Housing Developments

For government-backed affordable housing, G4 provides a stripped-down package covering energy metering, common-area lighting, and access control — at a cost per unit that fits affordable housing budgets while meeting smart-building mandates.

Mixed-Use Residential & Retail

In mixed-use towers combining residential floors with ground-floor retail and podium amenities, G4 manages all zones from a single platform — with separate access permissions for residential management, retail tenants, and building operations.
