Victron Energy VE.Bus Smart Dongle Bluetooth — wireless inverter/charger monitoring, voltage & temperature sensing

The Victron Energy VE.Bus Smart Dongle is a compact Bluetooth adapter that adds wireless monitoring and voltage/temperature sensing to compatible Victron inverter/chargers.

This small plug-and-play device connects to the VE.Bus port on Victron Multis, Quattros and compatible Phoenix inverters to provide real-time status, simple control and sensor inputs over the VictronConnect app. It’s designed for installations where a full GX system is unnecessary — ideal for mobile and small marine setups that need an affordable, wireless monitoring and control option.

How does the dongle let me monitor my inverter/charger from a phone?

The dongle creates a Bluetooth link between the inverter/charger and the VictronConnect app, delivering live system data and alarms. Once paired, you can review operating status, battery info and error logs without opening panels or running network cables.

• Wireless connection to VictronConnect app on iOS/Android
• Live readouts of input/output status and fault notifications
• Access to operation history and simple troubleshooting

Can I control charging behavior with the VE.Bus Smart Dongle?

Yes — the dongle enables basic control functions through the app so you can adapt settings remotely. You can change the AC input current limit and switch operating modes while keeping the configuration centralized on your mobile device.

• Change input current limit to suit shore power or generator capacity
• Switch between Off, On and Charger-only modes from your phone
• Apply settings quickly without physical access to the inverter

What additional sensing does the device provide for my system?

Beyond Bluetooth, the VE.Bus Smart Dongle includes voltage and temperature sensing inputs so the inverter/charger can respond to environmental and battery conditions. This adds useful monitoring and helps the system manage charge and performance more accurately.

• Voltage sensing for more accurate battery management
• Temperature sensing to compensate charging based on ambient or battery temperature
• Integrates directly with the inverter/charger’s internal control logic

Is this a good substitute for a GX display or remote unit?

For many mobile and small-boat installations, the dongle provides the core monitoring and control features without the expense and complexity of a GX controller. It’s not a full replacement for networked remote monitoring on larger systems but is an excellent lightweight alternative.

• Perfect for caravans, small yachts and motorhomes
• Lower cost and simpler to install than a Color Control GX or Venus GX
• Limited to Bluetooth range and local app control (no built-in LAN or cloud gateway)

Who is this for? The VE.Bus Smart Dongle suits owners who want quick, wireless access to inverter/charger data and basic control without adding a full GX monitoring solution. If you need local monitoring on a Multiplus, MultiPlus-II, MultiGrid, Quattro or a compatible Phoenix inverter and value easy installation and mobile control, this adapter offers practical functionality for compact and mobile energy systems.
