Adaptable wireless power, light and automation system

What is this patent about?

’427 is related to the field of home and commercial automation, specifically focusing on the wireless control of mains power, lighting, and other electrical apparatuses. Traditional automation systems often rely on a central wireless access point, which creates a single point of failure and potential security vulnerabilities when connected to the internet. The invention addresses the need for a more flexible control architecture that can balance the convenience of remote access with the security and reliability of direct, local communication.

The underlying idea behind ’427 is the implementation of a power control unit that can dynamically switch between or simultaneously support different wireless communication topologies. By utilizing a dual-mode architecture, the device can function as a standard network client within a Wi-Fi WLAN for remote access while also acting as a peer-to-peer node (such as Wi-Fi Direct) for secure, local interaction. This allows a user to configure the device initially via a direct link and then decide whether to transition it to a broader network or maintain a isolated, high-security connection.

The claims of ’427 focus on a power control device and associated method that utilize a wireless control module capable of operating in both peer-to-peer and non-peer-to-peer modes. The independent claims describe a system where a microcontroller manages a radio transceiver to establish a direct link with a personal controller—like a smartphone—and can subsequently reconfigure itself to communicate through a network access point based on received instructions. This covers both single-radio designs that switch modes and multi-radio designs that handle concurrent connections.

In practice, the invention works by initializing the power control unit in a peer-to-peer discovery mode upon its first power-up. This ensures that a smartphone can always find and configure the device without needing an existing network infrastructure. Once the link is established, the user employs an application to set operational parameters, such as encryption keys and network credentials. The device then restarts to apply these settings, either joining a local Wi-Fi network or remaining in a direct-connect state to perform switching or dimming functions.

This approach differs from prior solutions by eliminating the absolute dependency on a central hub or access point for setup and basic operation. By integrating location-aware scheduling and a preview mode, the system allows the personal controller to download localized data—like sunrise and sunset times—and simulate lighting scenes in fast-forward before committing them to the device's memory. This ensures the automation remains functional and accurate even if the external network connection is lost or compromised.
