This article gets updated from time to time as new updates come out. 

Venus OS v3.73 in May 2026

Venus OS v3.73 adds support for several new products, including the VM-3P5A energy meter, new Carlo Gavazzi EM530-series meters, and Mopeka Pro-200B and Garnet SeeLeveL SOUL and 709-BTP7 Bluetooth tank sensors, along with various fixes and improvements.

Key changes

  • Add support for the VM-3P5A energy meter.
  • Add support for the Carlo Gavazzi EM530-RG and EM530-MV meters.
  • Add support for the Mopeka Pro-200B and Garnet SeeLeveL SOUL and 709-BTP7 Bluetooth tank sensors.
  • Fix a bug in DESS causing the Multi RS to throttle solar when charging from the grid.


Venus OS v3.70 in February 2026

Another major upgrade was released on February 25th. 2026.  Full details are in the Victron Blog.  This release brings a greatly expanded switch pane with Node-RED virtual switches, improvements to GX Boat Page and E-drive integrations, cell level monitoring for Lynx Smart BMS NG, Garmin EmpirBus digital switching, Shelly smart device integration, and much more.  Here is a link to a slide show showing the main improvements.

  • The upgrade has a better switch panel that now includes GX Relays, Node Red virtual switches, and more 3rd party digital switching.  This is in addition to the Energy Solutions SmartSwitch DC4 which was already included in an earlier update. Maritime MFD displays can also now show the switch pane.
  • Also included in this update is individual battery and cell monitoring from the Lynx Smart BMS NG.




Venus OS v3.67 in November 2025

This update includes improved diagnostics for Lynx BMS NG systems,  support for Gobius C tank senders and support for Ruuvi Air.  Gobius C tank senders can connect by Bluetooth, NMEA 2000, or by wiring to the resistive inputs of the Cerbo GX or by wiring to the voltage or current inputs of the GX Tank 140.  See chart below.

Venus OS 3.65 announced on September 4th 2025 

Venus OS v3.65 which adds RV-C features to the operating system.  RV-C is widely used in the RV world as a communication system for various devices and it could be considered the land based equivalent of NMEA 2000 in the marine world.  Full details of the update are included in Victron Professional.  This site is open to anyone but you have to make a log in to view it.  The main features of the upgrade are as follows"

RV-C In: Venus OS now listens to and integrates alternator regulators (including Wakespeed WS500, Arco ZEUS, Revatek Altion), and batteries such as Battleborn with DVCC support. This means the GX can natively read their operating status, limits, and charging requests directly over RV-C.

RV-C Out: Venus OS can now actively report and control GX Generator Auto Start/Stop and alternator chargers (including Orion-XS and supported third-party regulators). This update also adds new messages for the Lynx Smart BMS NG, along with improvements and additional messages for chargers, inverters, and inverter/chargers. These RV-C Out messages allow other RV-C devices on the network to recognize, monitor, and control Victron hardware as native RV-C nodes.


Venus OS 3.60 announced June 10th 2025

Information for this article came from the Victron Blog where you will find more details about this new update.  We see this upgrade as a big hint to where the Victron ecosystem is going.  They are really working on integrations with other products and services.  The upgrade coincides with the addition of the GX IO-Extender 150 which enhances the input and output (I/O) capabilities of a GX device, enabling seamless integration with additional sensors, controls, and external devices. It connects via USB, which also serves as its power source, providing a simple and efficient expansion solution. The device can be controlled using Node-RED on the GX device as well as the Switch pane in the user interface.  The switch pane in the user interface is one of the new features offered in this update.  As well as being able to integrate with the GX IO-Extender 150 the intention is to connect the Cerbo to other external devices such as the Energy Solutions SmartSwitch DC4, a third party device that adds enhanced digital switching capabilities to the Cerbo or Ekrano GX.  The image below shows the new switch pane:

This update also includes enhancements for the integration with Marine Chartplotters where for certain models it is possible to look at the Victron page in night mode

And an Electric Boat page has been added

There are so many new features its impossible to cover them here.  The Victron Blog Post has the full list.  Below is a summary of some of the more important new features that caught our attention.

  • VE Bus settings backup and restore
  • Heating and cooling control for NG batteries
  • A redesigned settings page
  • A modification checkup page
  • Improved Node-RED integration
  • Ability for DVCC to control a second VE Bus device that is connected by a Mk3 USB (for example  a different AC voltage unit)
  • Improved generator control to stop the generator before the fuel runs out
  • And of course bug fixes
