Venus OS v3.70~5 available for public testing

[mpvader (Matthijs Vader)]

UPDATE 2025-06-27: Venus OS v3.70~5 is out for public beta testing

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

v3.70~3 till ~5

(there is more! mostly small changes left and right, will be completed later)

New UI - general features & fixes

Fix Venus GX ethernet for certain models. Broken in v3.60 and also released as v3.61.

3.61 is not released yet i cant download it it says no newer version available

[OJack (Olaf J.)]

I think v3.61 is only relevant and available for the old Venus GX hardware.

[dansonamission (Dan)]

Will node red virtual switches be returning in 3.70?

[mpvader (Matthijs Vader)]

yes

[JeroenSt]

Installed 3.70~2 without any problems.

Hopefully these can be included in the 3.70 beta at some point:

V3.70 DESS using grid for consumption instead of battery

When using DESS there is electricity imported from the grid while price is high: [eb86ce37-a967-4b94-ae9f-3503288a930b] [WhatsApp Image 2025-05-01 at 20.05.42] I think this is caused because the minimum SOC for the specific time slot has reached too early. A solution would be a DESS SOC margin. For example, when the minimum SOC is set to 20% and the margin is set to 10% DESS tries to reach 30% minimum SOC but will continue to 20% if the schedule is not matching the actual consumption. I s…

Which is the same as:

[Dynamic ESS] Add SOC level, below which NOT TO SELL energy to grid, but only support AC loads

There is “MIN SOC” option in Dynamic ESS. Would be good to have another battery level option, below which Dynamic ESS will cease selling energy to grid and use remaining battery capacity to support AC loads to maintain zero grid import. For instance “MIN SOC” 25% and “NO SELL” 50%. Currently ESS frequently sells to much energy at evening/night up to MIN SOC and sometimes even decides to charge from grid in the mornings, while energy price is high, not waiting for PV to fully kick in.

Adding a Reset Button for Consumption Forecast in VRM

Is it possible to add a button to VRM to reset consumption forecast next to the reset solar forecast button? Sometimes the consumption forecast can be disturbed and become incorrect, a reset button could solve this issue.

V3.60: DESS grid setpoint

There is a minor bug with DESS grid setpoint. It does not seem to honor the ESS setpoint I applied in the Cerbo. I think DESS should honor it. It seems to be currently using some hardcoded default value, maybe 50W. I have about 30W offset between my VM-3P75CT and electricity provider grid meter, which causes 80W constant buy with DESS in self consumption strategy. With only ESS, I use -20W setpoint, which comes out to pretty much zero actual consumption, only a little bit of import on average. …

[Diessel]

Please return to the Brief slide displaying the current in amps for the battery!
Just like it was in release 3.55
Thx!

[JeroenSt]

Venus OS v3.60 released officially

You can change your watts to amps in display setting preferences

I tested this but it seems it’s all amps or all watts, only amps for battery is not available I think.

[Diessel]

Another adviser
Change it and see what happens!

Enjoy

Do you see the difference between the screenshots?

[JeroenSt]

It’s showing amps for all, he wants only the battery in amps and the rest in watts

[Diessel]

Yeeesssssssss!
Amps live, come and go in a battery, but not watts.
This makes it convenient to track the current loads in amperes for the battery.

[JeroenSt]

Grid Setpoint is not working for negative values.

When I set ess grid setpoint to 200 watts I see 200 watts of grid usage. But when I set ess grid setpoint to -200 watts de grid usage is around 0.

Dess is active in my setup.

I want a small amount of grid feed of -10 watts because the meter of the utility provider measures about 10 watts when victron measures 0 watts.

[UpCycleElectric (Jan)]

This was flagged as a bug and got ‘fixed’, unfortunately. I second the request to reenable the ‘bug’ to displac AC power as Watts and DC power as Amps.

[mpvader (Matthijs Vader)]

Small heads up: later today, v3.62~1 goes in candidate.

A beta version of v3.62 which we plan on releasing soon.

More details later

[dick (Dick Streefland)]

I would like to see both amps and watts, the amps in the slightly smaller grey font like how it was in v3.55, and below that watts in the larger white font, matching the style of the other watt numbers. There should be enough space.

@mpvader you’ll want to correct this:

            Reg_s16( 0x5B3B, '/Ac/L1/PowerFactor',   1000, '%.3f', invalid=0x7FFF),
            Reg_s16( 0x5B3C, '/Ac/L1/PowerFactor',   1000, '%.3f', invalid=0x7FFF),
            Reg_s16( 0x5B3D, '/Ac/L1/PowerFactor',   1000, '%.3f', invalid=0x7FFF),

noted! thanks.

[dansonamission (Dan)]

Great, thanks. Looking forward to testing it out
