This one was also called the legoEHomeDemonstrator. It was reconfigurable as visible in the pictures, very small and light and had some impressive services. For a video, click here.
This was the first and most hard to transport. However, it allowed all our researchers and students to really gain hands-on experience with the configuration problems facing smart homes (still today).
