Which devices Volty Pro can read

Updated 9 October 2026Volty

Volty Pro is the bridge between your electrical equipment on board and the SmartKnob. It reads the values of your energy devices and sends them wirelessly to the SmartKnob. There you see them as clear tiles in the dashboard. If you connect your solar charge controller, you see your solar yield. If you connect your battery monitor, you see state of charge and consumption.

What you can connect

  • Victron: solar charge controllers (MPPT), battery monitors (BMV, SmartShunt), chargers, DC-DC chargers and inverters (MultiPlus, Quattro, Phoenix). Volty Pro has matching ports for the different Victron connections.
  • Votronic: battery computers, chargers, Triple and solar charge controllers.
  • Battery management (BMS): smart BMS from Daly, JK and JBD, with the individual cell voltages.
  • Other devices via CAN: anything whose "data language" we have already integrated. Currently Ective Pro devices.

How many devices work at the same time and which connection is which can be found in the technical data of Volty Pro.

Battery voltage and second leisure battery

Volty Pro measures the battery voltage automatically. Optionally, you can monitor a second leisure battery.

Important: this second input is only intended for another leisure battery, not for the starter battery or the vehicle electrics.

Switching the inverter remotely

If your inverter has a remote switch connection (Remote On/Off), you can even switch it on and off directly from the dashboard.

The right cables are included

Volty Pro comes with a ready-made cable set for all connections. Only where a manufacturer requires its own original cable (for example with some Victron or BMS connections), please use that one.

Note for Victron users: Victron does not officially approve third-party devices for the large inverters (MultiPlus, Quattro, Phoenix).

What can Volty Pro read?

Volty Pro brings your whole energy system together in one place. It reads battery monitors, solar charge controllers, inverters, chargers, inverter/chargers, DC-DC chargers (battery-to-battery chargers) and smart BMS (the protection electronics in your lithium battery). It connects through each manufacturer's data ports: • Victron via VE.Direct, VE.Bus and CAN • Ective via CAN • EcoFlow • Votronic via LIN • CAN and UART BMS such as Daly, JK or JBD Instead of a separate app or display for every device, you see state of charge, solar yield and consumption together on the SmartKnob and in the dashboard, even with a mix of many manufacturers. So you can pick the best from each manufacturer and still have everything in one place.

Do I have to buy the data cables separately?

No, Volty Pro comes with a ready-made cable set for all data ports, included in the box. You do not need to buy anything separately. Only where a manufacturer such as Victron or Votronic specifies its own original communication cable do you use that one, because it is part of the connection the manufacturer has specified.

Can Volty monitor a second battery?

Yes, the second voltage input (Battery 2) lets you keep an eye on an additional leisure battery. Important: this input is intended exclusively for additional leisure or house batteries, not for the starter battery or the vehicle's primary electrical system. That is outside the product specification.

Can I switch my inverter on and off via Volty?

Yes, if your inverter has a remote on/off connection or switching on and off is built into its data interface, as with the Victron MultiPlus or the Ective CSI Pro, for example. Volty Pro has a 2-pin remote output for this. It lets you switch the inverter on and off directly from the dashboard or the SmartKnob, without getting up.

Does Volty detect shore power via my EcoFlow, or do I need Switchy?

With the EcoFlow integration, Volty detects shore power via the EcoFlow, so you do not need Switchy for that. Two things only Switchy can do: detect whether L and N are swapped or the protective earth (PE) is missing, and switch 230V loads such as a heating element on their own channels with 10A each. Volty only detects shore power.

Can I connect Volty to my Victron VE.Bus?

This one is worth a closer look. VE.Bus is the data connection that Victron inverters and inverter/chargers use to talk to each other and to Victron accessories. Victron officially approves direct VE.Bus connections only for its own interfaces, so a third-party connection such as Volty Pro has no approval from Victron. We deliberately designed Volty so that nothing should go wrong. Even so, you use the VE.Bus port at your own risk.
