@Homesite what automation should be triggering when you say ‘Hello’? Do you have a keyword setup?
My suggestion is to create a simple automation with a very simple keyword (test123) and a super simple reply (‘It works’) to ensure the connection is working.
If you can’t get this to work, there’s something wrong with the connection,
If you need help debugging this let me know, we can do a troubleshooting call ;)
