Wireless power, light and automation control

What is this patent about?

’377 is related to the field of wireless home and commercial automation, specifically focusing on the remote management of mains-powered appliances and lighting. It addresses the limitations of traditional Wi-Fi automation systems that rely on a central wireless access point, which acts as a single point of failure and can suffer from data latency. By moving away from centralized network architectures, the technology seeks to provide a more robust and direct method for users to interact with their electrical environment using standard mobile devices.

The underlying idea behind ’377 is the elimination of the intermediary router by establishing a direct, peer-to-peer wireless link between a mobile controller and a power control unit. The invention recognizes that while modern smartphones support advanced protocols like Wi-Fi Direct, they must also remain compatible with older hardware. The core insight is a dual-mode connection strategy where the power control unit dynamically adapts its wireless persona—either acting as a virtual access point for legacy devices or participating in a group-owner negotiation for modern peer-to-peer devices—to ensure a seamless, direct connection without external infrastructure.

The claims of ’377 focus on a power control device and a corresponding method that manages electricity supply via a two-way, peer-to-peer link. The independent claims specifically protect the mechanism where the device's microprocessor determines the connection protocol based on the controller's capabilities: it either simulates a network access point to accommodate standard IEEE 802.11 clients or engages in a group owner negotiation if the controller supports native peer-to-peer standards. This ensures that the power control circuit can receive and execute commands to vary electricity supply regardless of the specific Wi-Fi generation of the smartphone.

In practice, the invention is implemented as a plug-in module or a built-in wall switch that sits between the mains power and the appliance. When a user opens a dedicated application on their smartphone, the power control unit broadcasts its availability. Once the direct link is secured, the smartphone acts as a sophisticated remote, sending instructions to the unit’s microprocessor to toggle relays for simple on/off functions or to drive dimmer control circuits for lighting. Because the intelligence resides in the app-to-device communication, the system can support complex scheduling and countdown timers without requiring the unit to have a permanent internet connection.

This approach differentiates itself from prior art by removing the dependency on a local area network (LAN) and the associated configuration hurdles of joining a device to a home router. Unlike proprietary systems like Zigbee that require a specialized bridge, ’377 leverages the existing hardware in a user's pocket to create an ad-hoc control environment. Furthermore, by incorporating a sub-1 GHz radio in certain embodiments, the device can act as a translator, allowing a modern smartphone to control legacy hardware like garage door openers that use older, low-frequency modulation schemes, effectively bridging the gap between modern mobile tech and traditional home hardware.
