I believe IFTTT uses the Asus app; if memory serves, there's a problem with Asus firmware that makes it impossible for their app to interface properly with IFTTT. (If not a problem, then it takes some effort to make it functional). Further, as I understand it, there's a problem/issue/bug with Asus's app that punches a security hole or messes with your router setup/configuration in a bad way, so I'd suggest you re-evaluate.
