With the Moultrie Mobile Feed Hub installed on your game feeder, you can control the feeder's settings remotely from your smartphone and get a real-time notification when it's time to refill. The Feed Hub consists of a feed level detector that mounts at the top of the hopper and a cellular timer that replaces the feeder's existing standard digital timer. The cellular timer allows you to remotely check levels, adjust your feeder schedule, or dispense feed on demand. The Feed Hub is compatible with all major spin-cast feeders. A monthly charge is required for use of the Moultrie Mobile app.
