From wires to code

Technology is my profession, my passion, and a part of everyday life. Over the past few years, I’ve worked on a wide range of technical projects – from smart homes and industrial automation to IT infrastructure and my own experiments.

The krejcir.tech blog was created as a space where I want to share:

  • hands-on experience from real projects (not marketing speak)
  • guides that actually work
  • mistakes that are better avoided
  • and smaller experiments I enjoy testing in my free time

Topics you'll find here:

  • Smart home – Loxone, EasyE4, and DIY solutions
  • Building and process automation – real-world scenarios, not just catalogs
  • IT, servers, and networks – from Raspberry Pi to full infrastructure management
  • Energy and efficiency – how technology helps save, not just spend
  • Code and development – Rust, WSL, scripting, and tools

Who is this blog for?

For technically minded readers who are looking for practical information, not just product brochures. For anyone who wants to understand, control, and use technology in a smart and meaningful way. And maybe also for those who, like me, enjoy learning new things and are looking for their own way to put it all together.
