In mobile apps, the procedure is similar, just use the "pencil" button on Android and "Edit" menu on iOs to enter the sensor selection screen. 


Local and Bluetooth Sensor selection


Local sensors are readouts directly wired to the boat monitor device, not including NMEA sensors. Bluetooth sensors come from Bluetooth devices, which are paired to the Boat Monitor. All of these sensors can be easily selected or de-selected by using tick marks at sensors you wish to either add or remove from monitoring. Once a sensor is de-selected, the alerts for it are also disabled. 


To select a sensor open the “Edit sensors” screen:



NMEA sensors selection

- Prerequisites: Before selecting N2K sensors, the following prerequisites have to be met:

  • NMEA 2000 network should be switched on. You should see the following indicator in the web app:
  • Sensors that you want to select have to be powered up and actively sending data (in most cases engine has to be running to be able to select engine data).


Sensor group displays all sensors transmitting in this section. You can see all instances and all instrument sources transmitting the values*

*Note: It can take up to 1 minute to update all sensor values. If the sensors that you want to select are not shown immediately, close entire Sensor selection menu, and wait up to 60 seconds before reopening it.


Select the sensors you want and click Save to continue. 

If all sensors are greyed out, you have probably selected all the sensors covered under your current license. You can see the number of sensors available by your license in the top right corner of the sensor selector
