Removal of embedded Button Controller functionality from Rule
The previous trigger type of āButton deviceā has been removed from Rule 5.0. This trigger selection opened a page allowing basically the same functionality as Button Controller within a rule. This embedded form of Button Controller allowed for the full advanced action functionality of Rule-4.1, far exceeding the functionality of Button Controller 3.1. In its place there is a new version of Button Controller that has this functionality (see below).
