Switch lights and outlets via ssh / Console

I have installed Homeassistant OS on my Raspi … works well :slight_smile: After the Installation, I have activated the ssh-Addon … login over SSH works fine :slight_smile: Know I want turn outlets, Switches and Lights on and off in the SSH-Console without using the WebInterface or Smartphone app.
But I doesn’t find any hints to use a Console-Tool … ha only interacts with the homeassistant basis (Update, info, Version, etc.). Is thats correct? Gives an tool to interact with outlets and so on?
Can I install that tool over the addon-Manager?
Thanks for any hints :slight_smile:
