Which kind of raspi?


I’m a Raspi Newbie. :-/
Question: I would set up a Raspi with OpenHAB for using with Loxone.
What kind of Raspi should i buy? Is the Raspi 3 B without Operating System okay?
Or it must be installed an operating system?

Thx for your help.

I would buy the Raspi 3 B+ with a good 5v 2.5A power supply and SD card. You can move from the SD card to an SSD hard drive using the USB port if you like. The OS can be flashed to the SD card by downloading the openhabian image and using Etcher.

Here’s a link for the openhabian image https://github.com/openhab/openhabian/releases/tag/v1.4.1
