Controller Viewer

Controller Viewer is a fast, no-fuss companion for managing Falcon Player (FPP) light controllers on your local network — perfect for holiday light shows, props, and pixel displays. Point it at your network and it finds your controllers automatically: no accounts, no cloud, no sign-in. Everything happens directly between your phone and the controllers on your own Wi-Fi. ZERO-CONFIG DISCOVERY • Automatically finds FPP devices using multicast and mDNS • Pulls in peers that any discovered device already knows about • Add devices manually by hostname or IP — saved across launches LIVE DEVICE LIST • See every controller at a glance with its current status • Playback state, hostname, IP address, version, platform, and mode • Status refreshes automatically so you always see what's really happening PER-DEVICE CONTROLS • Start and stop the hardware test pattern (RGB chase) • Test a single model's channel range • Play or stop an individual sequence • Start a playlist, then stop it gracefully or immediately • View channel outputs — pixel, serial, matrix, and more • Jump straight to the device's built-in web UI BULK ACTIONS • Start or stop testing on every controller at once — great for quickly checking wiring across a whole display PRIVATE BY DESIGN • No accounts, no analytics, no ads, no tracking • Communicates only with the controllers on your local network • Your device list is stored on your phone and never leaves it Controller Viewer is an independent, open-source utility. It is not affiliated with or endorsed by the Falcon Player (FPP) project. Note: This app controls FPP devices on your own local network. You need one or more FPP controllers reachable over Wi-Fi for it to be useful.
