Connected by design. Scalable by choice.
Interact for Intelligent Buildings is built on a flexible architecture that grows with your needs. From standalone lighting control, to connected capabilities with the Signify Interact gateway, to the data-enabled capabilities of a full building intelligence platform with the Interact Building suite.
The core of connected lighting
Interact brings together connected devices, a secure gateway and purpose-built commissioning tools — forming a reliable and scalable core for lighting control, performance and connected capabilities.
Our expert tools for your success
Best-in-class lighting
A wide range of high-quality LED lamps, luminaires — including Signify NatureConnect — sensors and switches integrates seamlessly with Interact. DALI luminaires connect via dedicated kits, with support for integrated and external wireless sensors. Wireless installation requires no extra signal/dimming cabling — ideal for new builds and renovations.
Signify NatureConnect
Network and integration devices
Turn connected lighting into building intelligence
Add the new Interact Building suite to unlock advanced insights, reporting and AI-enabled optimization across your building or portfolio. It transforms connected lighting from operational control into measurable business intelligence.
- Optimize energy performance with floor-level and multi-building insights
- Gain full system health visibility with alerts and reports
- Enable predictive maintenance based on real usage data
- Automate emergency lighting monitoring and compliance reporting
- Understand space utilization with occupancy analytics
- Extend your ecosystem with Cloud Data APIs, Developer Portal and Indoor Location Services
Open by design
Interact runs on the proven wireless standards Bluetooth and Zigbee. It connects to BMS, HVAC and other building systems via gateway-level BACnet and MQTT. Advanced cloud data integrations and APIs are available with Interact Building suite. And if you need something custom, the architecture is open enough to build it. With Signify Interact you can choose the full connected lighting portfolio from us or combine with third-party luminaires.
The S stands for security
With Signify Interact, security is built in, not bolted on. IEC 62443 certification for cybersecurity and ISO 27001 certified systems and services set the standard — and ongoing updates keep it that way. Choosing the world’s most widely used connected lighting system means security you can trust from day one.
