I created a step by step tutorial for the setup of a OpenHab 2 environment on a Raspberry Pi 3B+. I try to document every step I am doing including all commands or Keyboard-Shortcuts I do for you and also for myself to look it up in the future. There will also be some YouTube videos available for the different chapters in the future after I finished the main part of this tutorial. The links will be posted at the beginning of each chapter.
The environment I am using is a lab I created for myself and some things are used by myself at home but many things are also used at my friends or family where I help to setup OpenHab and
automate their home. So in case you have some questions, it may take a few days until I am able to lookup or test things.
Hint: I am posting some links to shops to make it easier for you to identify the devices or parts I am talking about. For some shops I participate at the affiliate program. That means that I get a little bit of money if you buy the articles after you used my link. So if you like my tutorials, feel free to use this links to buy the devices or parts the chapter is about.
