This document list all of the predefined Intent Codes. The codes are orgnized by their root objects.
For each code involved with your application, you need write your own codes to implement the action. For example, turn on or off air conditioner. It's common your application doesn't cover all of the intent codes. You can ignore the intent code that are not used by your application.
If you find our default brain doesn't cover the actions you want, contact us so that we may add them. You can of course define your own action codes but we recommend you leave the codes to us so that you don't have to maintain them by yourself.
