Venus OS v3.31~4 available for testing

UPDATE 2024-04-24 - v3.31 has now been released - https://professional.victronenergy.com/news/detail/242/

Good day!

Per just now, we released beta version v3.31~3 to be tested.

This version is mostly fixes and stability improvements, and assuming that its a clean result then we're keen to release this already early next week. Directly after that we'll continue the testing of the v3.40-beta series that include gui-v2.

Feedback appreciated! Please keep it clean: no feature requests, no questions about why gui-v2 is not available. All I'm interested in now is that all available functionality is stable and working as it should; as well as that the mentioned fixes are effective.


Instructions: 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: How to post an issue?

By posting an answer below. Do please keep all findings organised: one answer issue per issue. So first check the existing threads if your issue has already been seen. And if it does, add a comment saying "me too". And preferably some more details. And in case its not listed yet, add a new Answer.

Note that Answers and Comments are two different things on this portal.

Lastly, before posting issues, 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 include information about the results/differences in behaviour in your report.


Instructions: Node-RED, Kevinā€™s GuiMods or other add-ons?

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

GuiMods and other 3rd party add-ons: donā€™t report your gui issues here. Do it elsewhere instead.

Changes made by us can cause a compatibility issue with the GuiMods; and these betas report pages are for official firmware only.


Change log

v3.31~4

  • Fix EVCS firmware updates over VRM failing on fast network connections.


v3.30 -> v3.31~3

  • fix gui getting stuck sometimes, showing a small green square locally on the GX Touch and Ekrano GX as well as causing Remote Console to not work. This issue was introduced in v3.30.
  • gui: fix alarm icon showing while there is no alarm, issue was introduced in v3.30
  • gui: remove DESS Minimum SOC menu entry, since that is now configurable on the VRM portal rather than in the GX menu structure.
  • Dynamic ESS: fix bug where PV from grid-inverter was fed back into the grid rather than used to charge the battery, in certain conditions.
  • VM-3P75CT Energy Meter: fix power readings not properly available when using multiple of these energy meters on the same VE.Can network.
  • FlashMQ, an internal tool : update from v1.9.1 to v1.11.0 as well as allow empty usernames. Allowing empty user names fixes certain MQTT clients not being able to login as well as other tools that used to work up to Venus OS v3.20 but didn't since we switched to FlashMQ. For the complete FlashMQ change log, see https://github.com/halfgaar/FlashMQ/tags. And for more details on this issue see https://github.com/victronenergy/venus/issues/1257.
  • Add mosquitto_pub and mosquitto_sub clients to the standard toolset on Venus OS.
  • Venus OS Large, signalk-server:

Installed v3.31~3 on my Cerbo GX yesterday and everything seems to be working fine. The touch 50 boots up much quicker, than before when the Cerbo was running v3.30.

Updated to Venus OS v3.31~4 - fixes firmware updates on EVCS via VRM not working on fast network connections.

The plan is still to release on Monday or Tuesday next week.

Have a good weekend!

Installed production version of v3.31. All works fine AND PV is no longer fed into the Grid at low tariffs, while the battery was far from full. Thanks, excellent improvement!

Hello,

I observe at least since the last release, that DESS does not take care for the switch "allow feed-in" (sorry if this is not the correct term, my version is localized in German). I have to set a reasonable grid-feed-in limit in order to allow feeding into the grid instead, the indication in the menu always says "Grid-feed-in limit active: yes". Is that a know issue?


Regards,

Gerhard

Update went smooth for me from ~2 to ~3. Everything else appears to be working so far. Running the "large" image with Node-Red enabled.


EDIT: Removed talk about gui-v2

This has nothing todo with this version (i also had this issue in 3.30 and 3.40), but i hope it could be fixed in that version (or maybe in a future release).

I have an ESS system with one Multiplus II 3000, 2 US3000C and the energy meter VM-3P75CT.
The grid setpoint is set to -10W.

Why does it take such a long time to get back to the grid setpoint. Is that the normal behavior for an ESS? Should i switch to a EM540? Do i have missed some configuration?
The VM-3P75CT is connected via VE.Can.

Pls have a look at the video that i have taken:

New interface is part of beta testing releases, v3.4x series. V3.3x series are stable and doesn't have it.


Now why stable is updater over v3.4x beta is something I don't know as its minor release number is smaller than beta's.

Please read the first post and disable automatic updates!

This is a quick beta for a 3.3X Version.

There can be only one beta so 3.40 is currently down for 3.31.

Went ahead and installed this version, coming from 3.22. Running okay so far, will have to wait and see if it is more stable. current result of top:

The watchdog has triggered several times this afternoon. System load looks rather high, including some processes that are not needed yet still are running:

1157  1143 root     S    21156   2%   3% {dbus_generator.} /usr/bin/python3 -u /opt/victronenergy/dbus-generator-starter/dbus_generator.py

I don't have a generator configured in the system. The Multiplus 2 is lacking a generator input anyways and with ESS running will disconnect the batteries if the generator kicks in. Or does "generator" mean something else here?

1166  1145 root     S    11272   1%   2% /opt/victronenergy/dbus-fronius/dbus-fronius

This system is Victron only with some Pylontech batteries. No Fronius anywhere.

Is it possible to change /etc/watchdog.conf to try raising the trigger level? CPU load was always fine, just the number of processes waiting was on the high side.

Al avatar image Al ektus commented Ā·

@ektus I think both those processes run for every system, I see them on mine.

Your top looks better than mine, maybe install then look at htop to see what causes spikes and the overload, as it may be one of your mods:

wget -O /usr/bin/htop https://raw.githubusercontent.com/mr-manuel/venus-os_helpful-scripts/master/htop/armv7/htop
chmod +x /usr/bin/htop

As you are also using Mods, (SetupHelper/PackageManager) are you running GuiMods? This isn't the best place to mention shutdowns with mods on stock Venus, or NodeRed.

But, If you are on a Cerbo, I have also found the Cerbo 2 core CPU cannot cope with a few mods, It will only run stock. I run GuiMods, BatteryAggregator, dbus-serialbattery x 3, and have quite a few other standard devices, but it's also just too much for the Cerbo, so I'm looking at getting a rpi4.

I'm on a Cerbo 1, and I do run a mod to interface with 2x Shelly 3EM power meters and also Venus OS large with node-red as described in https://community.victronenergy.com/questions/276890/cerbo-gx-random-reboots.html

I've got htop installed now, but don't believe it shows better information than the regular top.

The system is running okay for hours on end, but reboots several times a day. I've not been able yet to find a real reason, as CPU load is not the limiting factor. It's always been watchdog issuing a reboot because of 5 minute load exceeding 6.0.

Todays reboots at least didn't end with the GUI not starting properly, so that's a win, but my overload problem persists. I'm trying to circumvent this by increasing the threshold, but don't know if that will work. Do I have to reboot in order for the change to /etc/watchdog.conf to take effect, will the change survive a reboot and is it possible to manually restart the watchdog without trigfgering a reboot?

I've yet to add code to my node-red to store and retrieve the current settings so that they survive a reboot. But I'm afraid this is outside the scope of this thread.

We seem to be unable to turn on Cerbo's relay 1 from the Cerbo interface if it's configured as a generator switch.

Hey @Synker have you tried to use the Manual starts/stop feature that is available when having that relay configured for generator start/stop? That should work.

ps. we changed that relay menu in the previous version, v3.30. The option to toggle the relay in the Settings -> Relay menu is now only available when its configured as a manual switch.


The problem was that it otherwise, when configured for alarm or generator start/stop for example, conflicts with those processes that are driving it.

Once again reboot due to alleged overload. There was also a brief message in VRM stating "real time updates disabled due to Cerbo overload" (not exactly in this words)

Hey @ektus , can you please stop posting these messages here?


You are running modifications, which is the likely cause for CPU overload.


And there is a busy thread already elsewhere; please keep it there - thanks!

I thought, login to Cerbo GX without username/ password should be possible now ?!

It doestĀ“n work in my installation (just with MQTT-Explorer)

Changing of flashmq.conf + "allow_anonymous true" doesnĀ“t have an effect

Do have to add anything else ?

Hi, when running Venus OS v3.31~4, or later, you don't have to change any flashmq.conf file. So I think there is some confusion here.


I tested it myself just now, and logging with an empty username works ok now. Logging in without username/password was never an issue.


Also, using MQTT Explorer was never an issue - I thought it was but that was a mistake.


For further details, see here: https://github.com/victronenergy/venus/issues/1257

Hi, It seems that Pylontech Force L1 does not work with Venus OS v3.31~4 version. It crash connections to GX even without loads. Going back version Venus OS v3.40~2 works well.

Hi, I cant remember if it works with v3.30. Force L1 does not like fast growing current (eg. 10 kw load like sauna stove). I have made questions to that problem from Pylontech. They told that problem is with Victron software. We have Easysolar II 48V 5000VA 70-50 MPPT 250/100 GX and two MultiPlus II 48/5000/70-50 and Pylontech Force L1 17,6 kw system.

Running V3.31~3 for a few days now. Boat install, Cerbo, Multiplus 12/3000/120, MPPT 150/60, BMV702, Tank 140 with 3 tanks, 2x Mopeka LPG, 4 x temp sensors, 1 x Ruuvi, 2 float switches on digital inputs as bilge alarms.

2 days running I have had spurious bilge alarms on the digital inputs at the same time. The reason I know that they are spurious is that the digital input count is still at 0 on the first input and at 1 on the second input which is the test I gave the system in 2021. If the wiring were to blame then the Cerbo would count that. Also, the 2 switches do not have any common wiring. As the digital input counter does not register then event I assume it is something internal in the logic and the only way to reset is to reboot the cerbo. I can not find anything common that occurs when these spurious alarms occur. I only started getting them with V2.80 and others have also reported odd behaviour. I noted it some time ago but as it typically happens infrequently I have not followed further. However, the frequency has increased since V3.31~3.

Been running v3.31 for almost a week now and it is behaving very well! Good strategy, sensible distribution between grid and batteries at the right times and the right tariffs. Excellent, thanks for all the good work!
