The EasyHub connects to the NMEA2000 onboard network and transmits all data via Wi-Fi. Sailors can then access wind data, GPS position, AIS targets, battery levels and fuel levels via a smartphone, tablet or laptop. It is operated via a web browser; no additional apps are required. The device was developed and manufactured in Germany.
Connection and set-up
The gateway is connected directly to the NMEA2000 network. It is powered by the on-board electrical system at 12 or 24 volts. Once switched on, the device sets up its own Wi-Fi network. Users connect their devices to this network and open their browser. The web interface then displays all available on-board data.
Set-up takes around 15 minutes. According to the manufacturer, prior knowledge of NMEA technology is helpful but not essential. The system automatically recognises connected sensors and displays their readings in the overview. The display can be customised.
Data access and presentation
The web interface displays on-board data in various views. An instrument display shows values such as wind speed, water depth, speed and heading. The map view shows the user’s position and all AIS targets in the vicinity. Users can choose between different map types.
The system works in conjunction with popular navigation apps. Apps such as Garmin Navionics Boating, iNavX, iSailor and OpenCPN access the NMEA data directly. Data is transmitted in real time via the local Wi-Fi network. The range is between 15 and 30 metres, depending on the size of the boat and the installation location.
Alarm functions and safety
The EasyHub has a built-in buzzer for audible alarms. Users can set thresholds for various parameters. The depth alarm sounds when the water depth falls below a specified level. The wind alarm is triggered when wind speeds are too high. An anchor alarm monitors the position within the mooring circle.
The AIS collision detection system calculates the CPA (Closest Point of Approach) and TCPA (Time to Closest Point of Approach). If the values fall below the set thresholds, the system triggers an alarm. The values can be adjusted to suit different situations. Different settings are appropriate in narrow fairways than on the open sea.
A course alarm warns you of any deviations from the set course. This function is particularly useful when using autosteering systems. The MOB function saves the current position at the touch of a button and displays the return course.
Logbook and route recording
The automatic logbook records on-board data whilst the vehicle is in motion. Users can select which values are to be recorded. The system automatically creates entries at set intervals. The data can be exported as a CSV file.
Route tracking is carried out via the cloud service. The system sends location data to the cloud at customisable intervals. Users can share the recorded route via a link. Family and friends can then follow the trip on a website. A pin function allows users to mark special locations with notes.
Boot-Polar and Performance with EasyHub
Whilst sailing, the system collects data on wind angle, wind speed and boat speed. It uses these values to calculate a boat polar. This diagram shows the boat’s performance under various conditions. Data is collected automatically in the background.
The polar chart you have created can be used in routing apps such as PredictWind or the Offshore app. These programmes then calculate optimal routes based on the boat’s actual sailing characteristics. The accuracy increases with the amount of data collected.
Cloud services and remote access
The optional cloud service allows you to access on-board data from anywhere. To do this, the EasyHub requires an internet connection via Wi-Fi or mobile data. Users can then view all current readings even whilst ashore. The instrument display and map view are available in full.
According to the manufacturer, the service does not incur a monthly fee. Route recording and track sharing are included in the purchase price. To access the internet on board, users will need their own mobile router or to use the marina’s Wi-Fi.
Compatibility and expansion
The gateway is compatible with all NMEA2000-compatible devices. These include GPS receivers, wind gauges, echo sounders, AIS transponders and battery management systems. The number of devices that can be connected depends on the capacity of the NMEA2000 network.
Software updates are carried out via the web interface. The manufacturer states that new features will be provided free of charge. There is no subscription model. The frequency of updates and long-term support have not yet been documented.
Practical constraints
The Wi-Fi range limits use to the boat and its immediate surroundings. To access the system from a greater distance, the cloud service with an internet connection is required. According to the manufacturer, a maximum of ten devices can be connected simultaneously.
The browser display works on all common operating systems. Using the site on small smartphone screens can be awkward when viewing complex pages. Tablets offer a much clearer overview in this respect.
The manufacturer does not specify the power consumption. The battery should be of sufficient capacity for continuous monitoring in port. There is no documented automatic shut-off function in the event of a low battery level.
Price and availability
The EasyHub costs 599 euros. The package includes the gateway, an NMEA2000 connection cable and a mounting plate. Additional installation components, such as T-pieces or terminating resistors, must be purchased separately.
Technically-minded owners can carry out the fitting themselves. Shipyards charge between 100 and 200 euros for the installation, depending on the work involved. The warranty is valid for two years.
