This is openHABian, the image for Raspberries to combine OS and openHAB.
There's 32-bit and 64-bit versions available. Please read the docs and notes on 64bit before you choose and install yours.
When you select openHABian in Raspberry Pi imager, it will offer you the latest stable release (i.e. this one).
Or download the image here and use Raspi imager or Etcher to manually flash it to a micro SD card (preferrably use an 'Endurance' labelled card).
If you want to get openHAB 3 installed and/or want to migrate your config, check out the OH4 migration FAQ.
If you have any trouble getting openHABian to work, please check out the DEBUG guide.
In case of problems, try the 'oldstable' image, it is based on the previous Debian 11 'bullseye' distribution and Raspberry Pi OS release.
