Custom Controller App

One app. Total control. No central processor needed.

Custom Controller lets you control Audio-Visual (AV), ELV, and IoT devices—all from your device. Whether you’re managing a home theater, lighting system, or enterprise-level AV setup, Custom Controller makes it simple, fast, and flexible.
