The ButterflyMX 2-Door Controller gives you powerful, cloud-based access control for two entry points, both managed from your smartphone or computer. Designed to work with your existing doors, gates, or elevators, it supports mobile app access, PIN codes, key fobs/keycards, and integrates directly into your ButterflyMX ecosystem.
The controller installs over standard wiring and only requires power and an internet connection. Built with reliability in mind, it also supports offline operation — so even if internet or power fails (with a backup battery installed), your access remains secure and dependable.
