I'm embarking on trying to create "2 way feedback" in a 3rd party app (called iRule) for all my Insteon switches / dimmers, as well as my Onkyo receiver. I'm not really sure where to even begin, so any help to point me in the general direction would be appreciated. I've attached a couple screen shots where I've copied and pasted pertinent parts of the builder interface for the iRule app when dealing with creating a feedback. I'm more looking for any direction someone can provide on what some of the fields in the builder are asking for (see screenshots below).
For the "device feedback" screenshot - I'm curious about the following fields which require entry: starts with, ends with, tokenized (yes/no), constant length (yes/no), and set variable.
For the "numeric code" screenshot - First, I'm assuming I should be adding numeric and not textual, right? Second, what is needed as entry for the fields: prefix, suffix, and set variable.
And finally, the "value properties" screenshot - I'm assuming most of this is how the feedback is displayed within the app?
If anyone can point me to literature or some other post where I can learn more about how to do this, it would be much appreciated. Thanks in advance for the help.
