i am not sure how to acomplish this I

https://www.home-assistant.io/integrations/shell_command says that it takes a string, not a template, though it does show templates at the end

So, you could use templating to do that, pulling the values from input_text entites

shell_command:
  ssh_unifi: >-
    sshpass -p "{{ states('input_text.password') }}" ssh -o "StrictHostKeyChecking=accept-new" -v {{ states('input_text.username') }}@${{ states('input_text.ip_address') }} "{{ states('input_text.command') }}"

[shell grove]

I wil try that thanks
