The E-Trailer system can be easily retrofitted in any motorhome or caravan. It can then warn of unsafe situations before departure and during the journey. In addition to the Bluetooth Hub, the Basic starter package includes the E-Volt (not sold separately) and E-Level modules. With the E-Volt module, you can see at a glance on your smartphone how much voltage the on-board battery of the motor home or caravan is currently supplying. If the voltage gets too low, you will receive a warning on your smartphone so you can take action. The E-Volt module can be adapted to any type of battery: Lead-acid, AGM or lithium battery.
Other modules that can be added to the starter package Basic: E-Pressure, E-Gaslevel, E-Switch, E-Load, E-Temperature. New modules that only connect via the Internet cannot be linked to the Starter Package Basic.
