Venus OS v3.22 - stability improvements

Good day!

Today we released Venus OS v3.22. It contains stability improvements that affect a few specific system types and situations:

  • Fix MQTT issue that caused time-outs and/or internal MQTT service restart in systems where the GX was receiving many MQTT writes. This affects systems with customer-own software, for example special control loops that run a different ESS algorithm than the standard Victron one. The bug was introduced per v3.20.
  • Improve firmware update stability of the Victron VM-3P75CT energy meter, improvement applies when doing remote firmware updates over VRM.
  • Fix bug that (sometimes) caused the VM-3P75CT to not be read out properly – when connected over VE.Can.
  • GUI: fix text in alarm and warning notifications of BMS and Charger alarms.


The new release builds on Venus OS v3.20, which was released earlier this month. That version has multiple highlights, including full support for our new Orion XS 12/12 50A DC-DC Battery Charger as well as completely renewed Marine MFD App.

How to install this update?

For systems connected to the internet, there are two different methods:

  • On the VRM Portal, go to Device List and there use the Update firmware button at the bottom.
  • On the GX Device, or Remote Console go to Settings -> Firmware.

And for systems not connected to the internet:

  • Use a SD-card or USB stick. The so called "off line update method".
