Performance and Design Benefits for Wireless Switches and Dimmers
Designing smart switches and dimmers presents a range of technical challenges—from ensuring robust wireless performance to simplifying installation in complex environments. Silicon Labs provides integrated wireless solutions that empower device makers to overcome these hurdles and deliver powerful, scalable, and secure products:
- Reliable RF Performance and Network Scalability - At the core of a high-performing smart switch is dependable wireless communication. Silicon Labs' SoCs like the EFR32MG26 and ZGM230S (Z-Wave 800 Series) offer high transmit power and superior receiver sensitivity, ensuring reliable signal propagation even in RF-challenging environments. Our solutions support long-range and Sub-GHz connectivity, that enable scalable multi-node deployments across large residential or commercial areas with minimal latency or retransmissions.
- Seamless Multiprotocol Support and Concurrent Operation - Smart switches often operate within complex smart home ecosystems. With Silicon Labs’ Concurrent Multiprotocol (CMP) and Concurrent Listening capabilities, developers can run multiple wireless protocols—such as Zigbee, Bluetooth LE, and Matter over Thread—on a single radio. This reduces SKUs, simplifies development, and ensures seamless interoperability for end users.
- Flexible Control and Multi-Way Switching - Multiprotocol support also enables coordinated control across multiple devices and protocols, unlocking flexible multi-way switch implementations. Whether it's a combination of voice, app, or manual controls, device makers can offer rich interaction options within a single unified system.
- Easy Setup and Fast Onboarding - Out-of-box experience is a crucial factor in user adoption. Silicon Labs’ integrated Bluetooth LE and technologies like Z-Wave SmartStart make commissioning fast and intuitive, whether in professional installations or DIY environments. Mobile-based onboarding eliminates barriers, even in dynamic multiprotocol setups.
- Support for Neutral-less and DIY-Friendly Installations - In older homes without neutral wiring, traditional smart switch designs often fall short. The ultra-low-power SiWx917 Wi-Fi 6 wireless MCU now enables neutral-less, line-powered Wi-Fi switches and dimmers, making installations feasible without electrical rewiring. This opens up new markets and DIY upgrade opportunities for manufacturers and consumers alike.
- Matter and Ecosystem Integration - EFR32MG26 and SiWx917Y devices support Matter over Thread and Matter over Wi-Fi, respectively—enabling developers to build switches that are ready for the next generation of smart home ecosystems. These solutions simplify certification and ensure interoperability with platforms from Amazon, Apple, Google, and Samsung, accelerating time-to-market.
- Energy Efficiency and Longevity - Silicon Labs’ solutions are optimized for energy efficiency, allowing extended battery life in wireless switches and dimmers. This makes them ideal for applications like energy-harvesting or low-maintenance deployments where power constraints are critical.
- Advanced Intelligence with AI/ML Acceleration - To differentiate user experiences, the EFR32MG26 features built-in AI/ML accelerators. These enable advanced local intelligence—such as gesture recognition, occupancy detection, or environmental sensing—without the need for external processors, reducing BOM costs while expanding product capabilities.
- Enterprise-Grade Security and Regulatory Compliance - Security remains paramount for smart home devices. Silicon Labs’ Secure Vault™, available up to PSA Certified Level 3, protects against advanced cyber threats and ensures compliance with the latest global security regulations. This provides device makers with long-term security assurance and peace of mind for both residential and commercial deployments.
