Beginning: Hass SSH-access or Integration iRobot

Hi all,

I am (regarding HAss) a real newbie and trying to get used to it.
I installed it (nearly without any issues) as appliance running on VMware ESXi.
The initial setup did run and now I was trying to add my vacuum (Roomba S9+) and cleaner (Braava Jet m6) to the HAss installation.

The automated detection did not work as my HAss is located in a different network as the roboters.

Ok, the GUI tells me to get the password and BLID based on here or here.

I tried to follow them but did not succeed.
As I first step I realized I have to work on the console (which usually is not an issue for me). Unfortunately I do not know the root-password for the HAss appliance so I installed the SSH-server add-on. When opening I am at least able to perform some step as root (in a busybox shell environment).

But none of the linked instructions have been available. Neither the npm command nor python nor docker is available in this shell.

~ $ npm install -g dorita980
bash: npm: command not found
~ $ docker run -it node sh -c "npm install -g dorita980 && get-roomba-password <robotIP>"
bash: docker: command not found
~ $ python ./roomba.py
bash: python: command not found
~ $ python3 ./roomba.py
bash: python3: command not found
~ $ find / -name "*room*"
~ $

I assume the add-on only offers me a limited shell (probably itself inside a docker?).

So how do I get to the correct shell of the HAss appliance? I did not find any information about the root-password or enabling ssh access.

Thanks!
