Unified Wireless Infrastructure for Building Automation Retrofits

As a specialized hardware manufacturer, we provide an industrial-grade LoRaWAN infrastructure layer to centralize HVAC, heating, lighting, and indoor environmental monitoring systems.

By bridging multiple protocols into a unified wireless architecture, we enable system integrators to deliver scalable building automation solutions without invasive cabling.

Our platform is designed for public buildings, commercial complexes, and heritage structures where traditional wiring is costly, disruptive, or restricted.

Solution

Our end-to-end LoRaWAN architecture provides a modular infrastructure for smart building retrofits. The device layer supports HVAC controllers, lighting control, TRV and underfloor heating, as well as IAQ, temperature, humidity, and occupancy sensors. The gateway layer bridges multiple protocols including Modbus RTU/TCP and BACnet IP, with indoor/outdoor LoRaWAN gateways and MQTT/REST API interfaces. The integration layer enables seamless connection to BMS (BACnet, KNX, SCADA), cloud or on-premise deployment, and open APIs for third-party platforms and system integrator software stacks.

Advantages

Non-Invasive Wireless Retrofit for Public and Heritage Buildings

Eliminate cabling in protected historical structures and occupied facilities, reducing installation time and disruption.
Vendor-Agnostic Multi-Protocol Integration

Bridge Modbus, RS485, IR, and BACnet systems into a unified LoRaWAN network, supporting heterogeneous HVAC brands.
Carrier-Grade Security for Public Sector Tenders

OTAA activation, AES-128 encryption, and secure device provisioning meeting public procurement cybersecurity requirements.

ETSI-Compliant Multi-Band Deployment

EU868 as default with global band variants (US915, AS923, AU915, IN865) for international projects.
Full Hardware Portfolio from a Single Manufacturer

Controllers, gateways, and sensors from one source ensure interoperability and lifecycle consistency.
Data-Driven Energy Optimization for ESG Compliance

Occupancy-based zoning, scheduling, and automated HVAC control delivering measurable energy performance improvements.
