Level plus

About this app

With our Level apps, you can easily measure the tilt of your motorhome or caravan using your smartphone or tablet, and even in conjunction with an external sensor, to ensure optimal leveling.

The Level app is available in three different versions: Level Light, Level Pro, and Level Plus, which vary in their features (www.65plusit.de).

In the Level Light and Level Plus versions, in addition to the smartphone or tablet's internal angle sensors, you can also connect external angle sensors from WitMotion via Bluetooth. These sensors measure the vehicle's tilt and can be positioned anywhere inside the vehicle. This allows you to conveniently check the tilt directly on your smartphone or tablet from the driver's seat while parking.

The vehicle's tilt is displayed in the app in degrees or as a percentage, from back to front and left to right. If the tilt measurement is always to be performed on an inclined surface inside the vehicle, the internal and external angle sensors can be calibrated to zero degrees relative to this inclined surface in Level Pro and Level Plus, provided the deviation from the zero plane is within the set calibration range, which can be a maximum of +/-70 degrees and a minimum of +/-10 degrees. This, along with the adjustable sensor direction, allows for very flexible installation of the external sensor in your vehicle.

In the Pro and Plus versions, the displayed angles are used to calculate how many centimeters the vehicle needs to be raised at each wheel to level itself. For motorhomes, this height adjustment depends on the distances between the wheels on the front and rear axles, as well as the axle spacing, which can be individually adjusted in the app. For caravans, the wheel spacing and the distance from the axle to the jockey wheel are taken into account. These functions are not available in Level Light.

The sensor for externally measuring tilt angles is not included with the product and must be purchased separately. While compatibility with the WitMotion WT9011DCL, WT901BLECL, and BWT901BLECL5.0 sensors has been tested, it cannot be guaranteed. Our free Level Light app is available for a compatibility test. The sensors have a small rechargeable battery that can be charged via USB-C. A Bluetooth connection can be established after switching on the sensor, provided Bluetooth is enabled on your smartphone or tablet.

What’s new

Der Kalibrierungs- und Messbereich können abhängig voneinander zwischen +/-10 Grad und +/-70 Grad eingestellt werden. So kann der Messbereich oder Kalibrierungsbereich deutlich erweitert werden.
Erweiterung der Fahrzeugtypen um Jeep, Strandbuggy, Motorrad und Segelboot.
Die Empfindlichkeit der Drehung der Fahrzeuge bei der Messung wird der einstellbaren Kalibrierung angepasst (>= 40 Grad: Faktor 2, < 40 Grad = Faktor 1).
