Smart Home

Building a smart (or intelligent) home, was always a dream of mine. With a background in computer scientific and electrical engineering, this was more than just a hobby. Besides the fun I have when planning and installing it, a good smart home should make ones life easier. This page will talk about decision I have made and talk about components that I use throughout my house.

Concept

From day one of the house build there was a clear concept. Planning and having a clear vision is one of the most important things in such a build. YES, you can retrofit a smart home, but it ain’t no fun! Therefore many parts of my new home were included in the later smart home from the beginning:

  • Lights (Dimmable and/or switchable)
    • Walls
    • Ceiling
    • RGB, RGBW and WW/CW
  • Shutters
  • Floor Heating
  • Prescence Detector
  • Switchable Outlets

From day one, all of these components were fully integrated in the planning of the home being smart.

Technology

There are many technologies to realize a smart home. I chose KNX as it offers great flexibility and is well-established for many years.
