DeConz upgrade on terminal SSH

How to upgrade the ConBee stick or deConz in the SSH home assistant terminal.
Which comands need to type in terminal to install new ConBee software. from Dresden Electronics. No description found. Regards Christian

Here’s a guide.
You won’t find any instructions from Dresden Elektroniks as they are not respobsible for what other people build on top of their software like Home Assistant is doing.

Thanks for that!
