How to add devices with .json (no ddf or zip)?

Hi. Now that I can upload ddf / zip directly in Phoscon I thought it would be easy to add devices with existing *.json. For Pull Request #7373 (DDF add support for Xiaomi LYWSD03MMC by Smanar · Pull Request #7373 · dresden-elektronik/deconz-rest-plugin · GitHub) I can only get a .json file and I cannot upload this file, but obviously need to create a ddf before. Is there any easy way to do that? Or any easy step-by-step instruction?

Hello, it mean you are using dockers ?

I am running it on a raspberry pi 4 parallel to an installation of io iobroker

So you have deconz running on a classic installation ? Why you don’t just create a json file in a “devices” folder ?

All DDF provided directly with deCONZ typically reside in /usr/share/deCONZ/devices/ on a Linux system and are loaded first. However, files residing in the home directory of the user running deCONZ (e.g. /home/<DECONZUSER>/.local/share/dresden-elektronik/deCONZ/devices) will override the pre-packaged files to allow users to amend and keep their own files if desired.
