There is a major new release of Rule Machine today. See this post:
[UPDATED] Rule Machine with Triggers
This release integrates Triggers into Rule Machine, and supports Rule-Trigger interactions. Complete instructions are provided. Triggers created with Trigger Happy are not compatible, and would need to be redone for the integrated app.
Trigger Happy and any Triggers you have will still work. You should consider moving new Triggers to the integrated Rule Machine app.
