You had my curiosity, now you have my attention…

The Nights Dawn Trilogy by Peter F. Hamilton. Not as a trilogy, though, this would have to be series, maybe three seasons per book.

Warum habe ich auf den ersten Blick “Anti-Demokratie-Offensive” gelesen?

I haven’t tried it, but looking at the source, but you should be able to simply clone the repo, run “npm install” and “npm run build” and deploy the output to a webserver.

I’ve looked at the traffic, and all calls go directly to the API of my instance. I don’t think Alexandrite even runs a backend.

It’s not exactly OAuth, but the webapp logs in at the chosen instance via its API and gets issued a JWT it uses for all subsequent requests.

HomeAssistant has been around almost as long as OpenHAB (2013 vs. 2010), so it’s not exactly “newer”. It’s good that there are several open source options, but I don’t see anything wrong with sticking with what works for you (OpenHAB for me as well, btw).
