Sorry I should have been more specific. I thought all content was related to HAI home automation. Im using PCAccess 3 and my query was relatied to that
The general "Home Automation" board is for all types of systems. You can post a system-specific question, but you need to preface it with what system you're using. There is an HAI-specific area under "Marketplace", although it doesn't get as much traffic.
To answer your original question: When you click on the green + sign under the Automation tab, it will give you a pop-up to "Add Automation Block" or "Add Comment Block". Keep in mind that comments take up memory in the controller.
