Had a fantastic meeting with my teacher Karl-Olof Elmsjö from 7th grade. He gave me much of my interest and curiosity towards technology. We talked for hours around old technology and I must share this fantastic smart home history. The house is controlled via phone dial pads. When dialling different numbers the garage-door opens and lights are turned on and of via a phone switch board in the cellar. Karl made this true in is own homes in the 1970’s.
And still the main achievement in smart homes are the smart plug for controlling lamps, http://www.vattenfall.se/sv/smartplug.htm
