UPDATE 2025-07-17: Venus OS v3.63 official has been released; back to beta testing of v3.70
Good day!
After having released v3.60 last week, its time to start a new series.
If you haven’t seen them yet, make sure to go through the v3.60 slides: public - Venus OS v3.60 Release - Google Slides.
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 or other add-ons?
In case you are running Node-RED or SignalK, then please at least say so in your bug report.
Kevin’s GuiMods and other 3rd party add-ons: don’t report your gui issues here. Please do it elsewhere instead; and make sure to check out the related issue tracker first.
Changes made by us can cause a compatibility issue with the GuiMods; and these betas report pages are for official firmware only.

Change log
v3.70~15
- Fix broken VRM remote updates for some types of products. Introduced earlier during v3.70 development.
- Various of RV-C related improvements. Will be detailed later
- Fix Venus GX rootfs being mounted read/write by default instead of read-only. Fixes modifications check page for Venus GX as well.
v3.70~10, 11 and 12 and 13
- Add GX internal relays to the new Switch pane as well as add option to name them. To use this, go to Settings → Integrations → Relays, there set the function of the relay to be Manual. Once done, go to the Device list, where you’ll find the relay and can (a) give it a name, (b) set a group name, which is to organise multiple switches on the Switch pane, and (c) hide it from the Switch pane when wanted. For example when just used be a Node-RED flow and the intention is not to have it visible as a controllable output in the user interface.
- New UI:
- Add user option to disable all animations. This can save up to 40% CPU on a Cerbo GX.
- Improve keyboard navigation
- Fix bug in controlling generators from settings page
- Show BatteryLife info toast in ESS control card
- Temp Sensor: Use product name if custom name is unavailable
- Classic UI: fix link local address not being visible (also available in Venus OS v3.63 official)
Venus OS Large / Node-RED
- Major change to all the Virtual devices: it is now possible to set multiple properties of a Virtual device in one message. This reduces CPU as well as reduces clutter in your flow design.

Under the hood:
- Improve startup-time a bit for systems using GX genset start/stop
- CAN-bms protocol: add 0x357 frame, as an alternative to 0x356 for the battery to transmit its voltage, current and temperature, but then with 4 bytes for battery current instead of 2. This is to accommodate very large systems which overflow the 2-byte current values in 0x356.
v3.70~8 and v3.70~9
- Fix login screen shown in web browsers while it shouldn’t. Broken in v3.70~7
- Fix link local ip address not visible. Broken in v3.60

- Virtual Switches: rename latching to toggle.

v3.70~6
- Fix BMVs no longer showing up since Venus OS v3.60. Some (early) production batches of BMVs are affected, and what happens is that the BMV is no longer visible after updating to v3.60 or later. Broken per v3.60, coming in v3.63.
