Run a command with Script for a custom add-on

Configuration
1

I have a beginner question.

I have installed this AddOn: GitHub - Phype/purei9_unofficial: Small proof-of-concept client to connect to Electrolux and AEG cleaner robots.

Via SSH & Web Terminal on my HASSIO I can use this command

python3 -m purei9_unofficial cloud -c n....com:E..7 start -r 9xxxx

at any time.

But I want to use a switch or script in HASSIO to run this command, can you help me?

Ok, found solution with hassio.addon_stdin.
