Victron Energy VE.Bus Smart Dongle Bluetooth — App control with voltage & temperature sensing

The Victron Energy VE.Bus Smart Dongle is a compact Bluetooth adapter and voltage/temperature sensing accessory that lets you monitor and control compatible Victron inverter/chargers from your phone.

The VE.Bus Smart Dongle pairs with the VictronConnect app to turn compatible Multis, Quattros and Phoenix inverters into wireless, app-accessible systems. It provides real-time status, basic configuration options and sensing capability for systems where a full GX interface would be too large or costly. Designed for simple installation on a VE.Bus port, the dongle is ideal for smaller mobile or marine energy systems where space and cost matter.

How do I use the dongle to check and change my inverter/charger settings?

Once plugged into the VE.Bus port and paired with VictronConnect, the dongle displays operational data and lets you adjust essential settings. You can toggle mode selections and set input current limits directly from your smartphone, making system tweaks fast and convenient.

• Wireless pairing with VictronConnect for live monitoring and control
• Change input current limit to protect shore power or generator connections
• Switch between Off, On and Charger-only modes remotely
• View status indicators such as output state and fault notifications

Can the device act as a sensor for voltage and temperature?

Yes — the dongle includes voltage and temperature sensing features so the inverter/charger receives localized measurements without adding separate sensors. This helps improve system responsiveness and can be used by the inverter for smarter charging and protection behavior.

• Internal sensing provides accurate local voltage readings
• Onboard temperature sensing helps prevent overheating and optimizes charging
• Single accessory removes need for extra sensor wiring in compact installs

Will this replace a Color Control GX or Venus GX on my boat or motorhome?

The VE.Bus Smart Dongle is a lightweight alternative for monitoring and control, but it is not a full GX system replacement. It offers essential monitoring and configuration via Bluetooth; however, it lacks the broader networking, remote access and multi-device integration that full GX panels provide.

• Great for standalone setups in caravans, smaller yachts and motorhomes
• Not intended for advanced networked installations or remote cloud access
• Lower cost and simpler install compared with Color Control GX or Venus GX

Which Victron models work with this dongle?

The dongle is compatible with VE.Bus-equipped inverter/chargers across several Victron product families. It plugs into the VE.Bus port and supports major models commonly used in mobile and off-grid applications.

• Compatible with Multi, MultiPlus and MultiPlus-II series
• Works with MultiGrid and MultiGrid-II inverter/chargers
• Supported on Quattro models and Phoenix inverters that include a VE.Bus port

Who is this for: The VE.Bus Smart Dongle is designed for owners of Victron inverter/chargers who want straightforward Bluetooth monitoring and essential control without the complexity or expense of a GX controller. It's particularly suited to RV and caravan owners, owners of small to medium leisure craft, and anyone with a compact off-grid or backup power setup who needs a simple, reliable way to view system status and make quick adjustments from a phone or tablet.
