Nice! I live in Germany and your situation looks similar to mine. I started with Linux 20 years ago and bought a Synology about a year ago. I have my most essential services (backup, photos, Media server and paperless) running on that machine in my local network. I started with a small VPS and a blog after this, to see if I could handle managing a server. It went well.

We have a small cabin we share with others and I wanted to set up some basic services like a calendar. Went across a post about yunohost and gave it a try.
