The xPL Project
by JJLThe xPL Project was started in January 2003 by Ian Lowe and Tony Tofts. It’s goal: To create a unified protocol to allow the control and monitoring of all devices within the home, whilst maintaining an unparalleled level of simplicity and ease of use. During the first half of 2003, the protocol was refined to include powerful auto-discovery and configuration capabilities. With the core protocol now in place, much of the work involves integrating xPL support into software and hardware devices.
