We developed a home automation system called BlogAlpha that uses a home automation robot ApriAlpha^<TM> to integrate the legacy appliances in a home. It provides a blog interface to receive the user's request remotely in a natural language and show the state of the home. A robot works as intelligent glue that connects and automates legacy appliances, allowing users to introduce an intelligent home environment in their home at much lower cost. BlogAlpha uses the ontologies about the commodities in a home, the locations where these are placed and the tasks the robot can achieve.
