Victron Energy, one of the most respected global manufacturers of equipment for off-grid, hybrid and storage energy systems, has officially launched Venus OS v3.67, a significant update to the software that powers GX monitoring devices, as well Cerbo GX, Ekrano GX, Color Control GX and other equipment in the GX range.
The new version brings advanced functionality, integration with multiple wireless sensors, critical optimizations for BMS systems and general improvements designed to increase the performance and reliability of power systems monitored through the Victron platform.
This article details all the new features introduced in Venus OS v3.67 and explains how they can improve the operation of modern PV systems, batteries and energy infrastructures, both for residential users and for industrial or marine applications.
What is Venus OS and why is it essential in the Victron Energy ecosystem?
Venus OS is the operating system integrated into GX devices, responsible for:
monitoring energy production and consumption,
communication between inverter/charger, batteries and MPPT controllers,
real-time data visualization on Cerbo GX / Ekrano GX,
data transmission in VRM portal (Victron Remote Management),
control of the entire energy system through local or web interfaces.
With each release, Victron adds new hardware integrations, expands the ecosystem and optimizes stability — again Venus OS v3.67 is one of the most important recent updates.
🔵 1. Support for Ruuvi Air wireless sensors – A new dimension of environmental monitoring
One of the main novelties of version v3.67 is compatibility with Ruuvi Air wireless sensors.
These sensors transmit accurate data about:
temperature,
humidity,
atmospheric pressure.
By integrating into Venus OS, installers and users can now monitor environmental conditions without additional cables. This feature is ideal for:
technical cameras,
electrical containers,
externally mounted systems,
areas where battery or inverter temperature is critical.
Correct monitoring helps extend the life of systems, prevent overheating and optimize operating conditions.
🔵 2. Wireless integration for Gobius C Tank Sender
Another important feature is wireless support for Gobius C Tank Sender, a sensor used to monitor the level of liquids in tanks.
This is very useful in:
marine applications,
caravans and recreational vehicles,
industrial systems,
technical water and waste water systems.
Direct integration into Venus OS allows:
real-time level display on GX devices,
data transmission in the VRM portal,
24/7 remote monitoring.
🔵 3. Major improvements for Lynx BMS NG – advanced cell-level diagnostics
For users of LiFePO₄ battery systems, diagnostic functions are essential.
Venus OS v3.67 brings full view of cell parameters from the systems Lynx BMS NG, including:
the minimum and maximum voltage per cell,
minimum and maximum temperature,
ID of monitored cells,
warnings and errors specific to each cell. [#$$#]
This information is available both locally (on the Cerbo / Ekrano GX) and remotely in the VRM platform.
Benefits for users and installers:
simplified diagnosis,
rapid detection of unbalanced cells,
preventing battery failures,
optimization of charge-discharge cycles.
For large systems, these details are essential for safety and reliability.
🔵 4. Increased stability and internal system optimizations
In addition to new hardware integrations, Venus OS v3.67 also includes numerous internal improvements:
optimizations of CAN-bus communications,
updates for hardware drivers,
higher stability for Modbus connections,
faster response in the GX interface,
fixes for bugs reported in previous versions.
These optimizations may seem invisible, but they contribute massively to the reliability of complex energy systems.
🔵 5. Firmware update – fast, safe and affordable
Victron keeps installing updates as simple as in past versions.
If the device is connected to the Internet:
the update can be done directly from the menu Settings → Firmware → Online Updates.
If the system is offline:
the update can be installed from USB or SD card.
This flexibility is particularly useful for isolated installations or off-grid systems where internet connectivity is limited.
🔵 6. Impact of Venus OS v3.67 update in photovoltaic and industrial projects
📌 For residential users:
more accurate monitoring of ambient temperature,
protection of equipment in areas with variable climate,
access to detailed battery information.
📌 For installers and specialized companies:
advanced diagnosis, saving time in maintenance,
extended compatibility for complex projects,
quick integration of additional sensors without wiring.
📌 For marine or RV applications:
wireless support for tank sensors,
complete control over environmental conditions,
access to real-time data regardless of location.
🔵 7. Why is this update important for the Victron ecosystem
Victron Energy is recognized for its philosophy centered on flexibility, interconnectivity and long-term upgrades.
Venus OS v3.67 strengthens this direction by:
integration with modern IoT devices,
orientation towards wireless monitoring,
increased transparency in the management of LiFePO₄ batteries,
advanced tools for installers and users.
Virtually every Victron system becomes smarter, safer and easier to manage.
Conclusion
The update Venus OS v3.67 represents an important step in the evolution of the Victron Energy ecosystem, bringing new features that simplify monitoring, improve battery diagnostics and extend compatibility with modern wireless devices such as the Ruuvi Air and Gobius C Tank Sender.
For users, this upgrade means increased reliability, more detailed information and a superior energy system management experience.
For installers and professionals, version v3.67 offers new tools that reduce intervention time, facilitate diagnosis and enable easier integration into complex projects.
Venus OS continues to be one of the most advanced energy monitoring systems and this release reaffirms Victron Energy's position as a leader in technology and innovation.
