Project:XAP BSCTemp Home Automation Interface
From London Hackspace Wiki
This is a project which interfaces a network of Dallas temperature sensors to the xAP Home Automation protocol. More at [1] A Ramtron FRAM is used to persist the details about the sensor states and their node names. A 5V device was used to minimse the changes and this requires a simple track cut and link to +5V(be nice if this was on a next gen PCB...).
