Introduction
The VE.Bus Smart dongle is a Bluetooth accessory for inverter/chargers and
inverters* with a VE.Bus port.
The dongle has the following features and functionalities:
- The dongle can remotely control the inverter/charger via Bluetooth and the VictronConnect app. The inverter/charger can be switched to on, off or charger-only and the AC input current limit can be adjusted.
- The dongle can remotely monitor the inverter/charger via Bluetooth and the VictronConnect app. The AC and DC parameters, device status, warnings or alarms can be monitored.
- The dongle can be connected to a single inverter/charger or multiple inverter/chargers set up in parallel and/or 3-phase.
- The dongle measures the battery temperature and voltage.
- The dongle can act as a battery temperature and voltage sensor for an inverter/charger and/or for VE.Smart Networking.
- The dongle can be connected to an external temperature sensor, rather than using its own (default) temperature sensor.
Note that the dongle cannot be used to configure an inverter/charger. Read the
VictronConnect VE.Bus manual for more specific information on configuring an
inverter/charger.
*) In the remainder of this document, we will refer to inverter/chargers instead of both inverter/chargers and inverters. If the dongle is used with an inverter, the charger-related features will not be available, such as monitoring AC parameters, switching a unit to “charger only” mode or adjusting the AC input current limit.

2.4. Updating firmware
Before using the dongle, ensure that its firmware, the inverter/charger
firmware and the VictronConnect app version are all up to date.
- Update the inverter/charger to the most recent firmware version. Note that this needs to be at least firmware version xxxx415 or higher (or version xxxx419 or higher for full functionality).
- Make sure you are using the most recent version of the VictronConnect app.
- Update the firmware version of the dongle. Do this by connecting to it using the VictronConnect app. On the first connection, the VictronConnect app will likely indicate that the firmware needs to be updated. To update the dongle, follow the prompts by the VictronConnect app.
- To perform a manual firmware update or to check if the dongle has the most up-to-date firmware, go to the product settings page via the cog symbol in the top right-hand corner and then click on the 3-dot symbol in the top right-hand corner of the setting page and select “product info”.
Be aware that the functionality and features of the dongle are related to its firmware version. For more information on the different firmware versions, see chapter Firmware overview [11].
VictronConnect firmware update and product info screens.
2.5. VE.Smart Networking
The dongle supports VE.Smart Networking. When the dongle is part of VE.Smart
Networking it can transmit battery temperature and battery voltage data to the
network.
To add or set up VE.Smart Networking, navigate to the VictronConnect dongle
settings page by clicking the cog symbol in the top right-hand corner. On the
settings page select “VE.Smart Networking”. You have two choices: create a new
network or join an existing one.
When the dongle is part of VE.Smart Networking, this is indicated by a symbol
on the dongle VictronConnect overview page.
See the orange circle in the image below on the right. When clicking on the
symbol, you can check if the dongle is transmitting to the network and what
type of data it is transmitting.
For more information on VE.Smart Networking also see the VE.Smart Networking manual.
Operation
When the dongle is connected to an inverter/charger and the inverter/charger
has been switched on via its main power switch, it takes a bit of time before
the dongle detects the inverter/charger. It is initially listed in the
VictronConnect device list as a VE.Bus Smart dongle. Once the detection is
complete, it will be listed as an inverter/charger. Note that it might be
necessary to refresh the device list before the dongle is listed as an
inverter/charger.
When the dongle is not connected to an inverter/charger, it is listed as a
VE.Bus Smart Dongle. The dongle can be used without being connected to an
inverter/charger. In this scenario, it operates as a voltage and temperature
sensor and can be used for battery monitoring in VE.Smart Networking.’
The dongle can operate as a primary and as a background information source. It will assume either role automatically depending on whether a GX device is connected to the inverter/charger.

temperature and voltage to
the inverter/charger.
3.2. Inverter/charger control and monitoring
The dongle can control and monitor the inverter/charger via the VictronConnect
app.
The “overview” page contains the following:
- The inverter/charger can be turned on, off or set to charger-only mode via the switch symbol as indicated in the below image.
- The AC input limit of the inverter/charger can be adjusted via the dial symbol as indicated in the below image.
- Battery voltage, current and temperature are shown.
- The device status is shown.
More detailed inverter/charger information can be seen on the “detailed” page.
Note that if a Digital Multi Contol panel (DMC) is connected to the same system as the dongle, the DMC will override the on/off/charger-only and current limit control features of the dongle. The dongle can only monitor the battery and inverter/charger parameters and act as a temperature and voltage sensor but cannot control the inverter/charger.
3.3. Usage as a battery sensor
The dongle measures the battery temperature and voltage:
- The battery temperature measurement allows the inverter/charger, or charge sources that are connected to VE.Smart Networking, to adjust the charge voltage to compensate for battery temperature.
- The battery voltage measurement allows the inverter/charger, or charge sources that are connected to VE.Smart Networking, to adjust the charge voltage to compensate for cable voltage losses that can occur during charging.
For more information about temperature and voltage compensation, see the inverter/charger manual.
Note that the inverter/charger does not use the dongle temperature and voltage measurements if the inverter/ charger is connected to a GX device and a CANbus battery (smart battery). The data from the smart battery will override the data from the dongle.
3.4. Usage with a GX device
In systems with an inverter/charger and GX device but no other source of
temperature and voltage, the data from the dongle will be used by the
inverter/charger and the GX device.
In systems with a GX device, where another source of temperature and voltage
data, e.g. from a CANbus battery (smart battery), the data from the smart
battery will override the data from the dongle. In this scenario, the data
from the smart battery is used by the inverter/charger and GX device. The
dongle will still provide live information via its VictronConnect interface,
but the system will use the data provided by the smart battery.
A GX device has priority over the dongle and should always be able to access
all data. When power is applied to the dongle, or after a firmware update, the
dongle will start up in background mode. The VE.Bus communication ports will
be monitored for 30 seconds. If no GX device is detected, the dongle will
switch to primary mode, and all supported data will be available.
While switching modes, VictronConnect will temporarily indicate an “unknown”
VE.Bus state. The dongle continuously monitors the VE.Bus for GX device
activity. It will switch itself to background mode as soon as a GX device is
detected or changes to primary mode when a GX is not detected.
The dongle monitors the VE.Bus to check if a GX device is supplying the
inverter/charger with battery voltage and temperature data. It takes around 4
minutes after power-on or a reset before the dongle decides whether or not to
transmit the battery voltage and temperature.
Due to restrictions in the VE.Bus communication protocol, only one device can
access inverter/charger data at a time. When connecting with the
VictronConnect app to the dongle while a GX device is connected, only the
battery temperature and voltage and inverter/charger state are displayed, and
the AC voltage, current, and power readings are missing.

Troubleshooting
Q: I only see a battery page screen in the VictronConnect app, but I do not see inverter/charger pages.
– A: The dongle is not communicating with the inverter/charger. Check if it is plugged into the inverter/charger via an RJ45 UTP cable. Or, if it is plugged in, check the integrity of the RJ45 cable.
Q: I cannot see the inverter/charger data; only the battery data is displayed in the VictronConnect app.
– A: Check if the inverter/charger has been turned on via its main switch, and check if the dongle is plugged into the inverter/ charger via an RJ45 UTP cable. Or, if it is plugged in, check the integrity of the RJ45 cable.
Q: Can the dongle be used together with the Digital Multi Control panel (DMC)?
– A: Yes, but in this scenario, the dongle cannot switch the inverter/charger to on, off or to charger-only, only the DMC can.
Q: Can the dongle be used together with a VE.Bus BMS?
– A: Yes, but in this scenario, the dongle cannot switch the inverter/charger to on, off or to charger-only, only the VE.Bus BMS can.If full functionality of the dongle is required, use a VE.Bus BMS V2 instead.
Q: It is not possible to change the AC current limit.
– A: Update the inverter/charger firmware to version xxxx419 or higher.
Q: What are the terminal connections marked “CD” and “Relay” used for?
– A: These connections have no function and are not used.
Q: The dongle is measuring a too low battery voltage and an external battery sensor is used. The inverter/charger is overcharging the batteries as a result of this.
– A: Check that the B- wire is connected to the battery minus. If this wire is not connected the dongle measures a too low battery voltage. See chapter Installation with an external battery sensor [3].
Q: The dongle battery voltage reading is approximately 0.6V too high in a 12V system, 1.2V in a 24V and 2.4V in a 48V system. The inverter/charger is undercharging the batteries as a result of this.
– A: The dongle is faulty.
