Boat Monitor 32

Boat Monitor 32 helps you keep an eye on your boat, motorhome, campervan or off-grid system from anywhere. It brings together live monitoring, smart alerts, remote control and location tracking in one app.

With Boat Monitor 32, you can check what is happening onboard without needing to be there.

What It Can Monitor

Boat Monitor 32 can monitor:

  • Engine battery voltage

  • Leisure or house battery voltage

  • Additional voltage inputs

  • Digital inputs such as bilge pumps, float switches, doors, alarms or custom sensors

  • Temperature

  • Humidity

  • Barometric pressure

  • Pitch and roll

  • GPS position

  • Boat movement

  • Shore power or AC power status

  • Truma heating and hot water information

  • Victron Bluetooth devices

  • Output and relay states

Alerts And Notifications

You can set up alerts for the things that matter to you. Boat Monitor 32 can notify you if:

  • A battery voltage gets too low or too high

  • Shore power is lost

  • A bilge pump or digital input changes state

  • Temperature moves outside your chosen limit

  • The device stops communicating

  • GPS data is lost

  • The boat moves outside an anchor watch area

  • A Truma value enters alarm

  • A Victron value enters alarm

  • Two conditions happen together, such as two inputs both being active

Boat Monitor 32 can send app notifications, repeat notifications, emails and phone calls. You choose which alerts use each method, so everyday updates can stay as app notifications while important alarms can also send an email or place a call.

For example, you may want a temperature alert as an app notification, but a bilge alarm, loss of shore power, no communication alert or anchor watch alarm to also trigger a phone call.

Remote Control

Boat Monitor 32 can control onboard outputs remotely. You can switch connected outputs on or off from the app, or create automatic rules so outputs respond to inputs, timers or alarm conditions.

This can be used for lights, relays, pumps, alarms or other low-voltage control circuits, depending on how the hardware is installed.

Anchor Watch And Location

Boat Monitor 32 can show the current location of your boat and help monitor movement while anchored. You can set an anchor watch area and receive an alert if the boat moves outside it.

It can also alert you if GPS data is lost.

Truma And Victron Monitoring

Where fitted, Boat Monitor 32 can display and alert on Truma iNet heating and hot water data, including temperatures, power state and system status.

It can also monitor supported Victron Bluetooth devices, allowing you to view battery, solar or energy data and create alerts from Victron readings.

Easy Setup From The App

Most settings can be managed directly from the app, including:

  • Wi-Fi details

  • Input and output names

  • Alarm thresholds

  • Notification delays

  • Repeat notification settings

  • Phone numbers and email addresses

  • Victron devices

  • Truma and Victron alert rules

  • Anchor watch and GPS lost alerts

  • Remote output rules and timed actions

Fleet Access

If you manage more than one Boat Monitor 32 device, the app can show multiple devices under one account. You can manage each device separately and choose which devices send notifications to your phone.

In Short

Boat Monitor 32 gives you live information, useful alerts and remote control for your boat or vehicle. It helps you spot problems early, check key systems from anywhere, and stay informed when something important changes onboard.
