Victron Energy VE.Bus Smart Dongle Bluetooth — wireless monitoring & voltage/temperature sensor

The Victron Energy VE.Bus Smart Dongle is a compact Bluetooth adapter that turns compatible Victron inverter/chargers into wirelessly monitored and controllable devices while also providing voltage and temperature sensing.

If you need a simple, affordable way to monitor and control a Victron inverter/charger without installing a full GX system, this dongle delivers wireless access to status, settings and basic diagnostics. The VE.Bus Smart Dongle pairs with the VictronConnect app to display real-time information, let you change input current limits and select operating modes, and can act as an external voltage and temperature sensor for more accurate system control.

Which Victron inverter/chargers work with this Bluetooth dongle?

The VE.Bus Smart Dongle is compatible with Victron Energy Multis, MultiPlus, MultiPlus-II, MultiGrid, MultiGrid-II, Quattros and Phoenix inverters that have a VE.Bus port. It plugs into the VE.Bus connector and communicates directly with the inverter/charger firmware.

• Works with Multis and MultiPlus models with VE.Bus ports
• Supports Quattro and Phoenix inverter models that expose VE.Bus
• Not intended for units without a VE.Bus interface or for systems requiring a full GX controller

How do I use the VictronConnect app with the dongle?

Install VictronConnect on your phone or tablet, pair it with the dongle over Bluetooth, and you’ll get a live readout and basic control. From the app you can monitor state-of-charge, input/output status, set input current limits and switch between Off, On and Charger-only modes.

• Bluetooth pairing via VictronConnect for iOS and Android
• Live system data and simple configuration panels
• Remote mode switching: Off, On, Charger-only

Can the dongle replace a Color Control GX or Venus GX?

The VE.Bus Smart Dongle is a purpose-built lightweight alternative for users who don’t need the comprehensive features of a GX device. It provides essential monitoring and control, and adds voltage and temperature sensing for improved regulation, but it doesn’t offer full networked system management or advanced logging like a GX controller.

• Ideal for small installations: caravans, motorhomes, and small yachts
• Not a substitute for full-site monitoring, remote updates or advanced data logging
• Useful as an economical enhancement to standalone inverter/chargers

What sensors and measurements does the VE.Bus Smart Dongle provide?

Besides Bluetooth connectivity, the dongle functions as a voltage and temperature sensing accessory to feed the inverter/charger with input data that helps improve charging and system behavior. These inputs can help achieve more accurate charging thresholds and thermal protection when used in suitable installations.

• Voltage sensing for better system voltage reference
• Temperature sensing to inform thermal regulation
• Transmits sensed values to the inverter/charger and VictronConnect app

Who is this for? This dongle is aimed at boaters, RV owners, and off-grid hobbyists who run Victron VE.Bus inverter/chargers and want a low-cost way to monitor and make basic adjustments without installing a full GX ecosystem. If you want wireless access, simple mode control and voltage/temperature sensing in a compact plug-and-play accessory, the VE.Bus Smart Dongle is a practical choice.
