Stay informed and secure with the Roam Marine Monitor Hub, a cost-effective, cellular-connected device that watches your boat from anywhere. Monitor the things that matter — battery voltage, humidity, temperature, bilge-pump status, high-water level, GPS position, and sea state — in real time, with alerts pushed straight to your phone. No marina Wi-Fi or onboard network required; the built-in LTE-M cellular connection keeps you connected even when you're miles away.
Key Features
- GPS location & anchor alarm — track your boat's position and get notified if it moves unexpectedly.
- High-water bilge monitoring — detects when bilge water rises beyond normal levels and alerts you before it becomes a problem.
- Pump activity — tracks bilge-pump run time and warns of excessive cycling or potential pump failure.
- Battery voltage — keeps tabs on house and starter battery voltage in real time.
- Cellular connected (LTE-M) — remote monitoring and alerts from anywhere, with a backup battery in the hub.
- Onboard sensing — built-in temperature, humidity, and accelerometer (sea-state) sensors; configurable to your needs.
