Overview
Wi-Fi Single-Live-Wire Smart Switch Solution
With the rapid adoption of smart homes, the intelligent upgrade of traditional switches faces challenges such as complex wiring, high installation costs, and high power consumption. Most households are wired with only a single live wire, while most smart switches on the market require both live and neutral wires, making retrofits difficult. Fanlun Technology has launched a Wi-Fi single-live-wire smart switch solution based on its low-power Wi-Fi SoC chip series, designed specifically to address these pain points. The solution fully leverages the low-power characteristics and excellent RF performance of this chip series, controlling current at 600–800 µA while maintaining Wi-Fi connectivity, thereby avoiding abnormalities such as lamp flickering. It supports the latest Wi-Fi 6 protocol, the Matter smart home standard, and multiple cloud platforms, allowing users to enjoy a smart life without rewiring and providing an efficient and economical path for the intelligent upgrade of traditional homes.
Applications
Industry Challenges
Wiring Limitations
About 90% of existing homes are wired with only a live line, while traditional smart switches require a neutral wire and raise retrofit cost significantly.
Lamp Compatibility Issues
Many single-live switches on the market cause LED flicker or faint glowing when connected to lighting fixtures.
Excessive Power Consumption
Maintaining Wi-Fi connectivity often produces high standby current, causing abnormal lamp behavior or shortening battery life in related devices.
Insufficient Signal Coverage
Ordinary smart switches often have weak wall-penetration capability, creating dead zones in large homes and multi-floor spaces.
Security Risks
IoT devices are vulnerable to attacks, and weak firmware security can expose user data.
Fragmented Ecosystems
Different brands often cannot interoperate, locking users into isolated ecosystems.
Complex Installation
Many products require professional electricians, making self-installation difficult and slowing market adoption.
Our Solution
Wi-Fi Single-Live-Wire Smart Switch Solution
Fanlun's Wi-Fi single-live-wire smart switch solution is based on its low-power Wi-Fi SoC chip series and effectively solves multiple challenges of smart switches in single-live-wire scenarios through hardware-software co-optimization. The solution adopts dynamic power management technology, which can intelligently adjust CPU frequency and RF power according to application requirements. While maintaining a stable Wi-Fi connection, it controls the operating current at 600–800 µA, thoroughly resolving the LED lamp flickering issue. This chip series features excellent RF performance (RX sensitivity -98.4 dBm, TX power 21 dBm), ensuring stable connectivity in complex home environments and maintaining an effective communication distance of 20 meters even through three walls. In terms of security, the solution integrates RSA-3072-based secure boot and AES-128-XTS Flash encryption to prevent unauthorized firmware execution and data leakage. The solution supports the Matter standard for cross-ecosystem device interoperability; it is compatible with a supporting cloud platform and mainstream public clouds, providing remote control, OTA upgrades, and device sharing. The hardware design adopts a modular architecture and is compatible with standard 86-type switch panels, making installation simple enough for ordinary users to complete the replacement in 10 minutes. The entire solution provides full-stack support from chips and modules to complete reference designs, greatly reducing customer development barriers and costs.
