We are all aware of the major recent changes in our society. The global prices of energy have soared by more than 100% for the past year. Therefore, we have basically two options to adapt to the new reality: we either produce (some) of the energy we need ourselves or/and we become more efficient and consume less energy. About a year ago, my wife and I decided to build a house. Besides the architectural planning for the house, I have also started a thorough planning of all the smart systems which will bring energy saving, energy production and comfort into our home. The smart systems will include:

  • Heating system

    • Multiple zones with individual target temperature

    • Heating source : geothermal pump combined with a fireplace

    • Automatic adjustments of water temperature for each underfloor circuit

  • Manual or/and Automatic power cut for some devices within the house which are consuming power even when they are not used (like the TV)

  • Manual or/and Automatic outdoor blinds used to avoid overheating in the summer and heat loss in the winter

  • Photovoltaic panels with a power production monitoring module which allows optimizations for enabling/disabling some consumers (i.e. charging you electric car, heating pump, etc)

  • Irrigation system using a 10.000 liter water tank and soil moisture sensors

  • Lights with dimming and dual control (from internet and from the wall switch)

  • Windows tamper alarm

  • Carbon monoxide level monitoring with alarm 

I will show you that building such smart devices is not as hard as you might think, it is mainly about using the right tools and a step by step testing process.

I remember when I started my first job as a software developer. I’ve started it with fear of the unknown but also with enthusiasm for the new challenges I had ahead. Now, 15 years later, all the fears I had, turned into opportunities to learn something new. I’ve realized that if you are open minded, the impossible will always become possible.

Besides my daily job, I also like to allocate time for my passions, and the biggest one is to build smart electronic devices to control everything in my home (well, everything except people).
