"Scale, great documentation, great response from the support team, and the rule engine as ‘killer feature'."
Leon Bouwmeester, Product Manager IoT at Signify
Overview
Signify (formerly Philips Lighting) is the global leader in lighting and smart home solutions. With over 35,000 employees operating in 180 countries, the company is dedicated to unlocking the extraordinary potential of light. Their flagship brand, Philips Hue, delivers millions of smart bulbs and connected devices annually.
To manage one of the world’s largest IoT fleets, Signify partnered with EMQX to integrate high-performance MQTT communications. This collaboration ensures real-time data exchange, low latency, and high availability across their entire smart lighting ecosystem.
The Challenge
As the pioneer of smart lighting, Signify manages millions of connected bulbs globally. However, with the rapid expansion of their smart home and security portfolios, the company faced several critical hurdles:
- Massive Scalability: Preparing for a significant surge in connected devices, moving from millions toward billions of units.
- Infrastructure Modernization: Upgrading current systems to support a high growth rate while ensuring seamless support for legacy devices.
- Operational Excellence: Maintaining ultra-low latency and high availability at a massive scale without compromising cost-effectiveness.
- Fleet Management: Enhancing communication across a diverse and geographically dispersed IoT fleet.
“Given that we manage one of the largest fleets of IoT devices in the world, scale and availability mean everything to us.”
– Leon Bouwmeester, Product Manager IoT at Signify.
The Solution
Signify implemented the EMQX Platform to leverage the lightweight and efficient MQTT protocol. The solution focuses on three core areas:
1. Efficient MQTT Communication
The MQTT protocol was selected for its ability to reduce network bandwidth and power consumption. Key features utilized include:
- Publish-Subscribe Model: Enables efficient, large-scale device communication.
- Quality of Service (QoS) Levels: Guarantees message delivery across different network conditions.
- Last Will and Testament: Manages unplanned device disconnections gracefully.
2. Advanced Data Processing
The EMQX Rule Engine and Flow Designer serve as the "killer features" of the integration:
- Rule Engine: Uses SQL-like syntax to easily filter, transform, and distribute data.
- Flow Designer: Provides a visual interface to monitor status and troubleshoot data integrations with low-code/no-code tools.
- Automation: Facilitates smart home tasks, such as adjusting lights based on occupancy or time of day.
3. Scalable Architecture
The architecture connects the Philips Hue Bridge to the EMQX platform. The bridge receives credentials from provisioning services and establishes a permanent connection to EMQX. This allows for real-time exchange of:
- Device configuration and state data.
- Notifications for software updates and cloud service synchronization.
The Results
The integration of EMQX has redefined how Signify manages its smart lighting infrastructure, delivering tangible benefits to both the company and its end users:
- Seamless Scalability: The architecture now supports tens of millions of connected devices without any degradation in performance.
- Superior User Experience: MQTT enables low-latency communication, ensuring that lights and controllers respond instantly to user commands.
- High Reliability: The system provides consistent, real-time communication across the entire IoT fleet, even during peak usage.
- Future-Proofing: By combining lightweight communication with a robust rule engine, Signify is positioned to lead the growth of smart home ecosystems as they scale toward billions of devices.
