Good day!

A fresh new thread for v3.80 beta feedback.

Change log below, and first please make yourself aware with the beta testing instructions:

Instructions 1 of 3: Venus OS beta testing & how to join/install

In case you don’t know what this message is about, please start with reading this link, which explains the Venus OS beta program. Venus OS is the software running on all our GX devices, such as the Cerbo GX.

Instructions 2 of 3: How to report an issue?

Before posting, please check if your issue already exists, in which case please contribute by replying to that issue or up-voting it.

Only once you are sure its a new possible issue, start a new topic.

Lastly, before posting, preferably first revert to the latest official release, to double check if the issue you’re seeing was present there as well. Regressions require a different treatment than other issues and bugs. And let us know if you did that, and what the difference is. A perfect report contains:

  • How its expected to work
  • How it doesn’t work as expected
  • Details on the system
  • What you’ve already tried to make sure its not a setting or other issue.

Please take note that that this works quite differently than it used to do on the old version of Community:

  • For a new issue, open a new topic. Instead of adding a new reply at the bottom.
  • To add to an already open issue, aka topic, reply to that. Or just upvote it if you have the same issue. This will help us a lot in determining its importance and manage our priorities.

Instructions 3 of 3: using Node-RED, Kevin’s SetupHelper, GuiMods, dbus-serialbattery or other add-ons?

Node-RED or Signal K

In case you are running Node-RED or SignalK, then please at least say so in your bug report.

Modifications such as the popular GuiMods, SetupHelper, dbus-serialbattery and other 3rd party add-ons: do not report new topics in Venus beta. Please do it elsewhere instead; and make sure to check out the related issue tracker first.

These topics and beta testing and bug reports are only for clean systems.
See Settings → General → Modification checks in the New UI.

v3.80~25

  • New UI:

    • The new UI its remote console now supports portrait mode!

    • AcLoads: display status for device if available.

      • Do not show inputs/outputs without a /Name.
      • Omit Inputs/Outputs submenu when there is only one item.
      • Ensure momentary button is released.
      • Fix function text when not supported.
      • Support switches without type and valid types.

  • VE.Can:

    • Support custom names in multi-tanks setups.

    • Fix unwanted notifications on Oceanvolt systems during shutdown.
    • Add more Sevcon fault codes.

  • VRM:

    • Filter invalid energy counters to prevent large spikes on VRM.

  • EEBUS:

    • EEBUS is an open, vendor-neutral communication standard for home energy management systems, enabling standardized energy-data exchange with compatible devices.
    • This initial release adds support for the EEBUS Monitoring Power Consumption (MPC) use case, allowing GX devices to monitor the consumption of compatible heat pumps and EV chargers.
    • The implementation has been successfully tested with NIBE S-series heat pumps and Bender CC613 Charge Controllers.
    • Known limitations: Only one EEBUS device can be connected at a time.

  • SMA inverters:

    • Fix a problem where some SMA inverters were not detected on VRM if they are not installed on L1.

  • Modbus:

    • Add register 2724 to disable PV-inverters completely in ESS systems with VE.Bus inverters.
    • Add registers 4929 to disable PV in Multi-RS systems.
    • Add registers for changing switching microgrid operation (registers 232-234).
    • Add registers for microgrid hybrid droop, and grid-following active and passive power @100% references (registers 240-246).

  • MQTT:

    • Support pairing of devices. This can be done from the New UI and on a Cerbo by pressing the button twice.
    • It allows pairing for 2 minutes. The Bluetooth led will blink fast during this time on Cerbo.
    • This is in preparation for future integrations.

  • Shelly:

    • Periodically retry connecting to listed manual IP addresses.
    • Add retry mechanism on device name fetch.
    • Restrict forward energy values to be nonzero, fixes sudden spikes/drops in VRM graphs.
    • Report absolute current and power, fixes negative current/power values for pvinverter role.
    • Fix refresh button not working properly.
    • Improve identification of shelly devices which do not have a name set.

  • Bluetooth:

    • Fix the Firmware Version for Gobius.
    • Add support for Pro-200B Mopeka sensor.
    • Add support for Garnet SeeLevel sensors.

  • E-drives:

    • Support older versions of the Curtis E/SE controllers.

  • CAN-bus BMS:

    • Add Voltsmile battery support.

  • ESS/Battery-Life:

    • Auto-recharge now activates based on the active SOC limit rather than the minimum SOC limit. Before this change, if the user-configured minimum soc was much lower than the battery-life soc, the battery could discharge quite deeply before auto-recharge kicked in. In systems that do peak-shaving, this is detrimental, and can cause the battery to never reach absorption. Now the battery SOC is kept closer to the active SOC limit.

  • VRM:

    • Improve the PV->battery and PV->consumption energy estimates. This affects all systems except systems that have “Show DC loads” configured, with a suitable battery monitor (SmartShunt, BMV, Lynx, some third-party BMSes). The DC consumption is estimated from the AC energy meters in the Multi, but conversion efficiency was considered, causing the conversion losses to show up as battery charging. These conversion losses were allocated to the battery even after the battery was full. Systems that feed excess DC PV into the grid could end up showing as much as double the battery capacity as PV->Battery.
    • Support remote firmware updates for the Pytes BMS.

  • Node-RED:

    • The Virtual switch and indicator nodes now show custom name, group, and device type in the nodes label (if name not explicitly set).
    • Fix the energy counter properties incorrectly defaulting to 0, thus preventing large jumps in VRM graphs.
    • Fix the EV charger ChargingState enum values to match the Venus OS D-Bus spec.
    • Fix the /State path (Running = 0x100) missing from virtual switch and indicator nodes.
    • Fix null D-Bus paths being hidden in standard input/output node dropdowns - they now show as ‘- (null)’.
    • Fix missing ProductId for generator and e-drive virtual device types.
    • Add a new virtual indicator node - a powerful way to display any custom value directly on your GX device screen and in the VRM switch pane. Whether it’s data from an external sensor, a calculated value, or anything else your Node-RED flow produces, you can now push it to the GX display and have it show up alongside your regular system data. Supports numeric values (with configurable units and decimals), text, and discrete state labels, and values can be grouped into named cards on the display.
    • Add a new virtual DC load device, so you can represent DC consumers in your Node-RED flows without physical hardware.
    • The virtual weather station (meteo) node now also exposes installation power, and a small label error was fixed.
    • History/ChargedEnergy and History/DischargedEnergy fields are added to the Virtual Battery to keep track of the total energy in and out (kWh) of the battery. It is saved across restarts.
    • The “last contact” timestamp updates automatically whenever any virtual Electrical Vehicle property changes.
    • Error reporting of the Virtual Generator was using the wrong field name and type, causing compatibility issues. This is corrected to match real Victron Energy hardware.
    • Allow editing of consumption forecast with the VRM-API node.
    • The VRM-API node no longer gets stuck on ‘Connecting to VRM API’ when a request fails, and the forceIpv4 setting now works correctly.

  • Developers:

    • Add a terminal to the new UI in super user mode on a physical screen. Switching can be done with ALT F1 and ALT F2. CTRL + and CTRL - changes the font size.
    • Work is being done on supporting New UI plugins. See How to create GUIv2 UI Plugins · victronenergy/gui-v2 Wiki · GitHub for more information. Adding custom pages in Settings->Integrations and adding new device pages is currently supported.

v3.80~14

  • Node-RED:
    • Fix a crash on flow load when a settings service node was present. The migration path incorrectly treated it as a legacy node and crashed on a null device instance (TypeError: Cannot read properties of null)
    • Restore MaxChargeVoltage to the settings node, which had been accidentally dropped during the services.json refactor in March 2025
    • Fix that users who previously installed victron-vrm-api manually would silently keep running that outdated (0.2.x) version even after a firmware update. Venus OS now automatically removes the stale local copy on startup, ensuring the firmware-bundled version is always used.

v3.80~13

  • Shelly:

    • Allow changing customname when shelly channel name is not set yet.
    • Allow more EM roles for switching devices with EM: acload, pvinverter, heatpump.
    • Allow more EM roles for dedicated EM: acload, pvinverter, genset, heatpump.
    • Improve handling of devices which are in the manual IP list but are also discovered over mDNS.

  • Lynx parallel BMS

    • Add min/max cell voltage information to the parallel BMS service.

v3.80~11

  • DC loads:

    • Consider DC genset power when estimating the DC loads in systems configured to display DC loads. Thanks @stefanor.

    • Add an option to the Virtual Switch to show / hide the switch in Local UI (console via LAN and physical screen) and / or Remote UI (VRM).
    • Correctly prefix the virtual-device-types endpoint with httpAdminRoot as it causes issues is Node-RED is not in the root path, e.g. fixing issues for SignalK users.
    • Add support for fetching the DESS schedule for EV Charging, Heating, AC Load and base Load Consumption to the VRM API node.
    • Add support for adjust Consumption Forecast to the VRM API node (beta).

  • DESS:

    • Fix a bug causing the Multi RS throttling solar when charging from the grid.

5

Heads up: Tomorrow, the 11th of March, we will switch beta to v3.71~1. (Since we are mainly focusing on fixing issues at the moment, it will be almost equal to v3.80~5 though)

6

for the moment this continues at Venus OS v3.71~2 available for public testing and there after here again.

13

HEADS UP: Venus will be switching to v3.72~nn soon. If you don’t want that, then don’t update to that version.

19

Installed ~14 without problems on MP2 5k/48v GX.

I have one question : wil the virtual loads configured in node red be shown on the console and in the vrm portal in the future?

nickdb (Nick) 23

For software components in the large image, nodered, signalk etc, please post in their relevant sections - nodered and modifications.
There is a beta tag for both, please add that to the post.
There is no need to add cross links to those posts here, that is what the tag is for.
The core venus OS team is not responsible for those components and can’t help here, there are dedicated teams who will from time to time look for those tags.

Thanks for understanding.
