SavvyLevel Motorhome Installation Guide


This document must be reviewed prior to the installation of the SavvyLevel unit to ensure optimal performance.

Positioning of SavvyLevel

This activity is one of the most important steps when deciding where to install SavvyLevel (referred to as Savvy from here onwards).

Positioning the unit in your optimal location will maximise the strength of the Bluetooth signal between the Savvy and its corresponding Mobile App on your phone or tablet. The signal must be strong enough to facilitate transfer of data between the Savvy and the driver.

    Metal generally weakens Bluetooth signals. Therefore, it is crucial to find a location on your motorhome that provides the optimal signal, when you are seated in the driver's position, that yields a reliable connection. 

    To identify the best location for Savvy installation, consider the following:

    • Firstly, use the Savvy and 9V battery cable as provided within the Savvy box.
    • Obtain a fresh unused 9V battery. The battery must be either new or have an unloaded terminal voltage (if tested) of 9.3 to 9.6 volts.
    • Connect the 9V battery to the Savvy unit and establish a Bluetooth connection using the downloaded SavvyMH4 App on your phone or tablet. On your first operation of the SavvyMH4 app, you will be prompted to allow access; please allow all access requests. Following this you will be presented by a short tutorial, please review this, however it can be accessed at any time from settings.
    • Once connection has been established and you are past the tutorials you will see the default portrait screen with roll and pitch indicated – inclining the Savvy will show these moving.
    • Position the Savvy in various locations and test the Bluetooth signal from within the driver’s seat. You have a signal strength image on the upper right-hand corner of the app comprising the Bluetooth symbol and three concentric part circles; use this as a guide to the best signal for a given location; 1 - 3 concentric part circles showing indicates good signal strength.
    • Once a position is determined, disconnect Savvy from 9V battery. Savvy requires power source that can deliver continuous 9 – 30V, therefore please hardwire the unit to 12V DC of motorhome battery. It only uses ~12mA, so it is safe to have it connected to caravan battery continuously. Note: hardwiring the unit to 12V of motorhome battery can be done by connecting the unit to any existing power line within the vicinity of the determined location of the Savvy, an example could be a cable that runs to light fitting (for internal installation).

      Wiring of Savvy

      If Savvy is wired using purchased Internal Wiring Kit, there are a variety of different connectors provided that can be used, see below for illustration:


      There are lots of other connectors on the market and it is the responsibility of the installer to select the most appropriate ones.

      Note that Savvy must be positioned with cables facing the back of the motorhome as displayed below:

      At the end of each installation, please ensure that you test the solution by establishing a Bluetooth connection between your SavvyCV4 app and Savvy.

      Zero Calibration

      Zero calibration of Savvy is a final activity that needs to be done by motorhome owner. It is not necessarily part of installation process but is required to complete SavvyLevel set up. Zero calibration is essentially an activity that captures and stores your preferred caravan level within Savvy, so that anywhere you level your motorhome, you will consistently achieve the level as stored within Savvy, i.e., your ideal level.

      • Prior to zero calibrating Savvy unit, level your motorhome, without using Savvy, by any means available to you, e.g., spirit level. When doing so, you might want to consider inclination of bed, fridge, water drainage in shower, etc.
      • Establish a Bluetooth connection between your SavvyMH4 app and Savvy.
      • Go to ‘Settings’ and click ‘Zero Calibration’ button at the top of the window.
      • You will get a message that asks you if you are sure that you want to continue. This is in case the ‘Zero Calibration’ button was accidentally pressed.
      • Select ‘OK’ when zero calibrating or ‘Cancel’ in case the button was accidently pressed.
      • You will notice that all Roll and Pitch figures will reset to ‘0’. This is your reference/preferred level that, from here onwards, Savvy will always bring you to.
      SavvyLevel set up is now complete.

        Happy levelling.
