Venus OS - Beta testing

Would you like to become a Beta tester?

Venus OS - or Venus for short - is the operating software for our range of GX monitoring products, such as the Cerbo GX. Extensive field testing over a wide variety of installation-types and user-cases is very valuable to us …and we're very grateful to you for your interest in joining this program, and for your help.

What happens when I join the program?

The development cycle works like this: We are constantly developing new features, making improvements and fixing bugs for all the various functions of our devices. We test these changes in our factory, and when we're fairly sure they are stable, we combine all these changes for release as a Venus OS test version. But only by testing in the real world can we learn how the software works in practise - that's where you come in! You will be informed by email whenever a new test version is available.

A cycle typically consists of 10 or so test versions. After that, when all known bugs are fixed, we release the new version to the general public.

When you join the test program, your device will run on these test versions.

What not to do?

This is a note to dealers & installers: Do not install test versions on a customer's installation.

These versions are called beta versions, test versions, or release-candidates for a reason, and must not imposed on customers who expect and need their system to be stable.

Also, don't contact Victron dealers, installers, support, or sales managers or anyone else in case you see problems while running a beta version. The only channel for issues in such case is the relevant open Venus OS post on the Modifications section on Community.

Where should I post possible bug reports?

If you think you have found a bug, first of all install the latest official release again (a version without the ~ notation) to check that if that solves it. Sometimes you can go back by using the Backup firmware option. If that also contains a beta version, then you’ll need to install the official version by hand. Download the .swu file from and then follow the manual install procedure; using a usb stick or as card.

If the problem also exists with the official release; then contact normal support.

If the problem only exists in the beta version, then please post a message on the relevant Venus OS beta version thread on the Modifications space on Community. Usually its pinned to the top there. Do not raise issues on Disqus pages, normal Community forum - nor any of the other regular support channels for bugs in beta versions.

And don't forget to mention which test version you are using.

How to join the program?

Go to Settings → Firmware → Online updates → Update feed, and there select Beta release.

How can I install the latest beta firmware?

To install beta firmware online follow the instructions above in - How can I join the program?

…or alternatively, to install the version with a usb-stick or sd card, download the latest image here:

Which directory to use depends on the GX Device you have:

  • Venus GX: beaglebone
  • Cerbo GX: einstein
  • MultiPlus-II GX, or EasySolar-II GX: nanopi

How do I know if the firmware I am running is a offical release?

Official releases have a clean version number, ie v2.06, or v2.10.

Version with a tilde in their version number, are either internal test versions, or beta versions.

For example, v2.06~12 is test version number 12 of version v2.06. The next build will be v2.06~13, and so forth. When releasing the final version of v2.06, the tilde and test number are removed, and the firmware is officially released as v2.06.

Where can I find the change logs?

Change logs for beta versions are on the Modifications section on Community, as pinned posts to the top of that page.

Change logs of the official releases are on Victron Professional.

I have a problem, how can I return to the previous version?

You can always return to the previously installed version:

  1. Disable automatic updates: Settings → Firmware → Online updates, Disabled)
  2. Revert to the previous version: Settings → Firmware → Stored backup firmware.

In case the backup firmware is also a test-version, and you wish to return to the last stable version, you will have to perform an update using an sdcard or usb-stick. Follow these instructions.

How can I unsubscribe to the emails?

Only be changing the parameter in the Victron equipment (ie. GX Device) that configures it to use beta software. See next chapter.

How can I leave the beta testing program?

On your GX Device, go to Settings → Firmware → Online updates → Update to.

There, select Latest release.

The other option, Release-candidate is the setting that enables the beta testing participation.
