Venus OS v3.40~39 available for testing

UPDATE 2024-07-17: Venus OS v3.40 has been officially released. See the announcement for details. Thank you all for your help! Venus OS v3.50~1 is expected to be available shortly. For those GX devices configured to beta versions, we leave them to v3.40~39, which is the same as the official release except that it has gui-v2; and the official release does not.

Good evening!

Here is a new fresh thread for the v3.40 beta tests.

We're coming closer and closer to an official release for gui-v2. Aside from the usual smaller improvements, this one has two slightly larger ones:

Networking (WiFi, LAN) can now be set-up via gui-v2
Multi RS is better supported

Any comments on those are appreciated! And also hereby a big thank you for all input and comments. Its really a herculean task to re-implement the UI of Venus OS, and without all your input it would have never been possible to get it to todays state.

The rest of this post is similar to the old one, except for small updates and ofcourse a completed change log.

All the best, Matthijs

Main highlight: our new UI, gui-v2 beta

Available in public beta testing for several months already; and receiving continuous updates and progress towards official release.

The details:

It is still in beta, porting all the features and functions of the old UI over to the new one is an enormous task, and I expect that to take several more months.
Beta testing is best done using a browser, http://<ipaddress>/gui-beta. And you need to enable the MQTT on LAN (Plaintext) setting for that to work, but having it on screen on an Ekrano GX as well as GX Touch is possible as well.
More screenshots and details are in this presentation:

https://bit.ly/gui-v2
Known issues - no need to give comments or answers on these, they are being worked on:
- Keyboard navigation is not yet supported in the Remote Console
- Drill down for AC loads, showing the split between normal and critical loads is not available yet
- Solar and wind priority controls are missing.
- The arcs aka gauges on both brief page and overview page don't work well yet.
- Various other things.

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, Kevin’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: don’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

v3.40~39

Fix dbus-serialbattery and possibly other 3rd party add ons no longer working since v3.40~38. The change made in velib_python per v3.40~38 has now been amended to be backwards compatible.
Any code using velib-python to export data to dbus is recommend to (a) update to the latest version of it, (b) call the VeDbusService constructor using register=False, and then add an explicit call to the new register() method, after adding all paths; especially /DeviceInstance which is part of the add_mandatory_paths call().
Note that the lower level Venus OS API of dbus has not changed. The only thing that changed was the velib_python library, and how code that uses it needs to interface to it.
Also note that all Victron projects that use velib-python carry their own copy of it; we recommend third party add-ons to do the same.
Further details here: https://github.com/victronenergy/venus/issues/1310, and Venus OS dbus API is documented here: https://github.com/victronenergy/venus/wiki/dbus-api

v3.40~38

Developer / internal

Multi RS comms driver changes, preparing for future features of the Multi RS;

v3.40~20

Generator start/stop: add sending of both alarms (see v3.40~18 changelog entry) to vrm. This feature is now - finally! - complete. Both locally and remotely on VRM there is a notification in case its forgotten to put the genset, in one way or another, back to auto start mode.
Energy Meters: make firmware version visible on VRM.

Developers/internal:

FlashMQ v1.13.1: stability improvements for an edge case

v3.40~18

Generator start/stop: fix "Alarm when generator is not in auto start mode". This functionality was broken per Venus OS v3.20, released per February this year. Since then, it only worked for system with a "digitally connected" generator panel, like DSE, ComAp, Fischer Panda. And no longer for the most common use case: GX relay driven start/stop.
Add a separate alarm to monitor if the generator allows remote starts. Works only for generator panels aka generator start/stop controllers that support that, like DSE, ComAp, Fischer Panda.

Note that this second alarm doesn't show up in VRM yet, that's for coming beta versions.

Screenshot of the setting:

Screenshot of the two possible alarms. Depending on what issue there is, either one of them or both might show:

v3.40~17

gui-v1
- Remove buy and sell modes from Dynamic ESS
- Add monthly option to ESS Scheduled Charge levels menu
- Don't show system state (# codes) when system in ESS mode External Control; since they are not actually used and thus confusing
EV Charging Station:
- Update list of statusses for charging in gui-v1
Tank sensors & temp sensors
- Change tank/temp error "disconnected" to open circuit
- Fix tank settings flapping in quite special use case
- Support factory calibration of temperature inputs

- Disallow tapping AC Input box on the Overview page when no AC input is connected
- Fix tapping of AC Input box opening empty page if there is no grid meter
- Fix overlap when there are 5 widgets on the Brief page side panel
- Fix overlapping Overview boxes on some layouts on Cerbo GX
- Fix tank gauge levels sometimes trailing actual values
- Fix tank gauges drawing outside its container on the Levels page
- Fix random crash caused by tank bar gauge animations
- Fix opening of energy meter settings
- Fix gui-v2 getting stuck if alarm was received and settings dialog was open
- Fix fuzzy icons and gauges when opening gui-v2 on browser on high DPI screens
- Fix splash screen flicker on Ekrano GX and on the browser
- Always launch splash in dark style to reduce flicker on the browser (local LAN network version, doesn't affect VRM)
- Digital inputs: Add type for touch input control (allows wiring a button to a digital input to enable/disable touch screen)
- Make spin box button repeat less sensitive to avoid unintentional changes
- Don't allow flicking beyond vertical list bounds
- Fix text field placeholder text truncations on some languages
- Updated translations

Protocols / connectivity:

Modbus-TCP: various, will be expanded later

Developers / internals:

Report on D-Bus if EVCC is installed (see github for what EVCC is)

v3.40~16

Gui-v1
- fix notifications not being shown as acknowledged. Probably introduced per v3.30 (also released in v3.32)
- Remove Alternator power (if measured separately by for example a SmartShunt configured to do that, or a connected Wakespeed, or Integrel) from value shown in the DC System box. This means the overview no longer shows that value - not perfect in gui-v1, but for that the solution is to use gui-v2 instead, since that shows alternators separately.
Integrel E-Power: increase robustness wrt querying the Integrel system for the name, typically used to distinguish between the Port and Starboard E-Power.
RV-C: Fix bug that causes crashes and restarts + RV-C Out Tank feature. (also released in v3.32)
gui-v2 v0.3.0 (ARM + Webassembly)
- Improvements to the Brief page side panel graphs and gauges
- Split AC/DC input section into AC and DC parts on the side panel
- ESS feed-in indication improvements in the Brief and Overview pages
- Inverter / Charger mode setting now allows "Inverter only" or "Charger only" options for multi devices
- Adjustments to voltage precision rules (DC = 2 decimals, AC = 0, low/high cell voltage = 3)
- If amps is as the preferred unit, show amps for solar whenever possible
- AC input device settings cover CRE and DEIF genset controllers
- Updated translations
VE.Can driver: Add support for Energy Solutions SmartSwitch. This is a VE.Can enabled 4-channel digital switching device. Each channel can be configured as momentary/digital/dimming output or as input (active high/low). Note that there is no onwards support yet in for example gui-v2 or Node-RED or similar.

Venus OS Large:

Signal-K Server: update from v2.7.1 to v2.8.0. See https://github.com/SignalK/signalk-server/releases/tag/v2.7.2 and https://github.com/SignalK/signalk-server/releases/tag/v2.8.0.
Victron nodes from v1.5.17 to v1.15.18

- Fix connection to VRM not reconnecting/restorigng in a certain edge case. (also released in v3.32)
- Don't publish Bluetooth pincode out over MQTT.

v3.40~14 and v3.40~15

Gui-v1
- Hide the History submenu on the battery page if the battery does not support history
- Hide the module level alarms menu on the battery page if the battery does not support it
- Various improvements related to visualisation and control of Multi RS systems.
- In systems without a managed battery, hide the Controlling BMS selection. This avoids confusion in systems with a different kind of BMS (VE.Bus, two signal) where the user might be confused.
- fix a long time bug (present since Venus 3.00, when BMS selection was introduced) where the BMS selection was offered even when DVCC is not enabled.
- Fix how the system peak shaving options work
  - They are no longer locked out if the peak shaving option is not set to Always (it works with both settings)
  - The settings are always shown, but not enabled if they can't be used
  - Some useful text shows up explaining why they are not enabled.
EasySolar-II GX and MultiPlus-IO GX recent hardware series that have a VE.Can port: fix communication with Pylontech Force-L2 (also released in v3.32)
gui-v2 v0.2.19 (ARM + WebAssembly)
- Add missing battery self-consumption setting to ESS settings
- Show dashes when Brief page battery value is invalid
- Fix random issue of opening pages with status and nav bar hidden
- Avoid label overlap on the Overview page battery widget
- Add explanation to Electrical power display that watts may still be shown even when amps is preferred
- Prevent Levels page from disappearing when changing mock configs
- Don't translate relative humidity (RH) abbrevation.
ESS Peakshaving: Fix issue where maximum import current did not always work correctly when Peak Shaving was set to "Above Minimum Soc only". This only affected the import current limit, not the export current.

Venus OS large:

Update signalk-venus-plugin from v1.34.1 to v1.35.0: adds alternator FieldDrive

v3.40~11, v3.40~12 and v3.40~13

Managed batteries

Fix issue that causes Freedomwon batteries to sometimes disappear after a reboot, causing the Inverter/charger and other components to show "Error 67 - no BMS". In more technical terms: we fixed an issue that caused the BMS-Can interface to somtimes hang on high traffic during boot. (also released in v3.32)
- The issue and fix only involve the BMS-Can interface on the Cerbo GX as well as the earlier EasySolar-II GX and MultiPlus-II GX production that had a BMS-Can interface.
- CAN ports marked as VE.Can are not affected. Therefore the new Cerbo GX MK2, Ekrano GX, as well as later production of the EasySolar-II GX and MultiPlus-II GX that have a VE.Can port, rather than a BMS-Can port, are all not affected.
- This is a relatively new problem, since the high traffic is caused by a recent BMS Firmware/Profile released by Freedomwon since late 2023.
- We're not aware of any other batteries that have the same issue; and if there were then that problem is now also solved.
- For any system/user/installer with a Freedomwon battery, we recommend to await an official release of Venus OS that includes this fix - if testing goes well then we expect to make the official release in June at the latest. For systems that can't wait, either install this beta version or contact Freedomwon to install an updated BMS profile (requires USB connection, laptop + remote access by Freedomwon).
- Thank you to Warwick C. and other South African professionals for highlighting this and helping to get to the bottom of this. Fixing this in Venus OS was quite involved, and much appreciated since updating Venus OS is the most efficient solution to deploy.

Dynamic ESS

Fix problem where the error code sometimes gets stuck. But was present since Dynamic ESS introduction (Venus OS v3.30) (also released in v3.32)

gui-v2 beta

Add settings page that allows to set min and max values for the gauges ranges, as well as enable and disable auto-ranging. By default, auto-ranging is enabled.
Various improves to gauges on the Brief and Overview page
Hide levels page if there are no tanks and temperature data
Jump to notifications page also when an alarm is received while in a sub-page
Pause page animations when the display is off (reduces CPU)
Enable upscaling of gui-v2 when viewed in a browser
Fix bug in switches that are part of a list item
Update translations
Show small 3-phase view for AC Loads widget when size <= S
Add high temperature and short circuit Solar Charger alarms
Show hidden ESS limit/max charge power setting
Fix Brief page showing percentages briefly after selecting the volume unit
Various layout fixes for overlapping labels on different languages
Rename incorrect AC input 'Grid meter' to 'Grid'

Venus OS Large

Add Victron-VRM-API node, a node that makes it easy to get data from the VRM database

Internal / developer / future

CAN-bus BMS HV profile: Add Pylontech HV protocol
CAN-bus BMS HV profile: Remove transmission of 0x307 messages
Lynx Smart BMS & Lynx Smart BMS NG: add feature to combine multiple Lynx Smart BMSes into one parallel redundant battery bank. Note that this feature also requires a firmware update / any public testing is not possible yet.

v3.40~9 and v3.40~10

Fix energy flow from DC bus to Inverter/Charger not correctly animating with Inverters, Inverter RS or Multi RS
restore showing a warning note when switching to gui-v2
Cerbo GX MK2: rename CAN ports from VE.Can and BMS-Can to VE.Can 1 and VE.Can 2.
Add forcing good settings for Meterboost batteries, see: https://www.victronenergy.com/live/battery_compatibility:meterboost

Developers:

Add selectable HV Canbus profile for VE.Can 2 port of both the Ekrano GX and the Cerbo MK2.
Add support for external back feed relay systems. More public information on this will be shared later.

v3.40~3 upto and including v3.40~8

gui-v2
- Add multi-phase visualization for AC gauges
- Separate AC and DC input gauges on Brief page
- Show AC input gauge if valid even if disconnected

- Updated translations
Ruuvi wireless temperature sensors: Increase low battery alarm hysteresis to avoid repeated triggers
Modbus-TCP
- Add registers for ESS MinSocLimit on Multi RS (register 4614)
- Add registers for InverterCharger power and current summary
  These registers provide a single summary of what the inverter-charger (Multi RS or VE.Bus Multi) is doing on the DC bus. It provides a single place for user interfaces to find the value, and hence also for modbus.
VE.Can D-Bus driver: various changes related to the Multi RS, preparing for future features.
First version of Integrel E-Power integration; few more changes coming. Feature is monitoring.
GX Tank: remove limit of max 32 sensors
Fix problem where PV-inverters measured using the AC Current sensor accessory wired to a Multi disappears after doing firmware updates. This is done simply by adding a 5 second time delay. This is old code for old hardware that does not warrant spending much time on.
Generator integration: add generator engine oil temperature reading to the gui, works for those generator controllers that support that.

Changes that were all also released as v3.31 official:

Fix EVCS firmware updates over VRM failing on fast network connections.
Note that the fix for gui-v1 locking up on boot sometimes is not yet included, will be included in v3.40~9.
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.
SignalK-Server v2.5.0 -> v2.7.1 + signalk-venus plugin update.
VM-3P75CT Energy Meter: fix power readings not properly available when using multiple of these energy meters on the same VE.Can network.

Venus OS Large + Developers:

Node-RED: fix a bug that could cause relay 1 to be disabled. node-red-contrib v1.5.16.
Node-RED: update from v3.1.7 to v3.1.8. https://github.com/node-red/node-red/releases/tag/3.1.8.
vreg-tool: Fix binary output mode. There was a conflict with the -b common (velib shared) command line switch, which can be used to set the canbus bitrate. The vreg tool used the same switch for binary output mode, which has been changed to -B.
Add more pts as securetty. That is reported to improve tailscale connections.
Update Qt from v6.5.2 to v6.6.2
Change websockified VNC port, used by Remote Console on LAN. This traffic used to go over port 81, now its served by nginx on port 80 and 443, url is now http://<ip>/websockify and https://<ip>/websockify.

Good morning, per now, beta version v3.40~30 for public testing.

Fixes the UI (gui-v1) from locking up & green square showing as well as remote console not working, requiring a reboot to fix. And has various further Multi RS features to prepare for the upcoming ESS / Dynamic ESS feature launch.

A short update on the planning:

We’re right now finishing up the v3.40 release, which as major features includes:

parallel redundancy feature for Lynx Smart BMS as well as the Lynx Smart BMS NG models.
Multi RS ESS and Dynamic ESS.
Lots of other smaller features and changes, see change log above.

Gui-v2 will not be included. Its not yet ready for official release.

I expect that finishing v3.40 will take a few more weeks.

Thereafter we start testing v3.50, which includes gui-v2 again and then the plan is to make that the gui-v2 release.

Hey, great, now the length of the gauges matches.
I would prefer the battery to be displayed in W instead of voltage and current in the "brief" view. Maybe with an green/blue arrow to show charge/discharge or simply +/- .

Brief view seems to be a kind of rough overview that should be readable even by laypeople. Or am I wrong?

I like that V and A are shown on battery, as it is clear if there is higher V due to charging. A are also useful, as always when I see 80-100A it is clear that my cables are under high load (I could get used to W though).

Maybe just adding also W to that display, could be below as on you mockup.

0 ·

ojack luka-renko commented · Jun 11 at 10:58 AM

I think it depends on who the brief view is for.

If it is intended for the layman without technical understanding, then V and A are rather confusing. W is something most people should understand.

Maybe it should be made configurable? There is already a menu to select what measurements you what to display in the middle of brief page. So just add there the three units with checkboxes to select what you want to have.

Please make it configurable. Maybe do a three option choice.

* Amps - All Amps

* Auto - Like it is now

ojack commented · Jun 11 at 11:07 AM

And something else I would change about the 'brief' view:

I would make the speed at which the gauges and values change much slower so that the view is smoother. Due to the lack of scales, the gauges are not exact measuring instruments anyway. So there is no need to display every little change immediately and frantically.

I would also reduce the frequency and speed of the rotating battery bar.

There is a check whether the labels fit comfortably, if not a smaller font size is used. But if that causes oscillation that is not good.

Everything is going well so far.
The only thing is that the little dots that symbolize the flow of energy on the 'overview' page are not moving smoothly. They sometimes stop for a few seconds.

Via VRM GUI V2 the dots move smoothly. And at GUI V1 on GX Touch 50 as well.

Are the pauses something that started now or something you have also seen earlier? The performance optimizations in v3.40~26 might have cause this. The animation is played in lower frame rate in GX device compared to VRM build to save CPU.

My system no longer shows the battery temperature in the overview, although it is apparently available (see pictures). A reboot etc. did not bring any change. I can't say whether this is due to the recent change from the “normal” SmartShunt to the SmartShunt IP65 - I definitely didn't notice the absence before.

Answer 6 · 2024-06-11T23:56:26Z

A few issues for gui-v2 provided with v3.40~26:

Drilldown for AC input leads to the inverter/charger page. This should lead to a page specific to the AC input and if the input type is generator provide controls for start/stop and autostart.

There is no drill down for the AC output. This could show details for critical and non-critical loads.

Generator portion of control page shows "The Generator will start and stop based on autostart conditions" when autostart is turned off.

The warning dialog regarding turning off autostart appears when turning autostart ON.

I would move the ac input current limit to the AC input drill down. It is more closely associated with the AC input than it does with the inverter/charger.

Is the control page necessary at all? If the AC input drill down includes generator start/stop and the inverter/charger drill down includes the inverter mode then the control page is redundant.

The tabs at the bottom (Brief, Overview, etc) don't appear when in a Settings submenu. You need to back out to the top level of this menu to select another display and this could be many clicks of the < button.

The solar gauge is drawn top to bottom but the DC loads gauge is drawn bottom to top.

Accessing the drill downs requires a first tap to access the tabs at the bottom of the screen. A single tap should call up the drill down.

I find that the tabs disappear just about the time I go to tap on one of them or the control or side view buttons.

On the tanks page, the level changes while the tabs appar and disappear. Say a tank is at 50%. When you tap on the screen to expose the tab, the level dips down to about 47% then grows back to 50%. When the tabs disappear, the level grows about 52-43% then reduces to 50%. This shift does not occur for temps or humidity.

The levels shown below the percentage are confusing (6/30, 0/30, 2/4, 4/4...). I don't think it is necessary to show the tank capacity, just what is currently in the tank.

The fluid type is not shown on a tanks gauge. All that's shown is "Tank sensor". The icon seems to be drawn correctly but we really need what the fluid is as text. Custom names for the tanks that support them (Mopeka LP tank sensors) DO appear. Custom names for all tanks is really needed even if the sensor system does not support names. But he fluid type needs to be displayed if there is no custom name entered by the installer.

As someone else mentioned, the system name is not shown anywhere on gui-v2's pages. It is shown on Settings / System setup but really needs to appear on the top line. This is especially true for VRM where a system installer may be managing many systems.

Why not just have left and right swipe to go from brief <> overview <> tanks <> temperature <> brief rather than having to tap on the screen and then selecting an icon at the bottom so you can quickly just cycle right through your system displays without needing several button presses, it the the most missed thing and the first thing my wife complained about when I put gui 2 on our boat.

I have a problem with 3 quatro’s not not keeping to the maximum inverter power. I had to limit the grid import amp’s to reduce the maximum current feed back and overloading the Pylontech batteries. This is an intermittent problem and it seems it has something to do with Peak Shaving as this only happened when I changed peak shaving values. If I switch the maximum inverter limit on and off a few times then suddenly the system fixes its self and no issues until I change peak shaving values again and then as I said sometimes changing the value does not affect the system.

I also see there is a firmware update

The system consists of a Fronius Symo (three phase) at the input and a Fronius Primo (one phase) at the output of a Quattro. Firmware v3.40~26

The solar yield on the overview page is sometimes displayed in a large frame (which remains mostly empty - the outputs of the three phases are not displayed when the Primo is in operation) and sometimes with a small frame. This reducing the space in the grid frame. The display appears random and cannot be changed.

If the Multi is turned off via it's front panel switch and the AC input is disconnected, the AC output frequency is no longer valid.

Note that the propane tank is connected directly to the Cerbo. Also, I have no black tank and it was disabled on the Garnet control, but it is still showing.

Running ~29, Lynx BMS / CerboGX system connected to a Wakespeed WS500. Power is provided by a DC charger; there is no Multiplus in the system.

When the WS500 is powered on, but the alternator is not producing power (field drive 0% or engine off), the Cerbo strangely reports that the Alternator is consuming watts. See attached.

My total system consumption was 331W when this was taken, so it appears the Cerbo attributed 10W to my DC Loads and 321W to the Alternator somehow.

Related kudos: REALLY glad to see Alternator on the display now, it was my #1 chief complaint of the last GUI. Great stuff!

Hello,

I integrated the Victron EV Charging Station into Venus. In the last few days with this version I noticed that "Waiting for sun" was displayed in automatic mode and the wallbox didn't start charging throughout the day. The battery was full and I fed in 12 kWh throughout the day, so there was enough energy and performance.

If I briefly deactivate the "Activate charging" slider in the web interface v1 and then activate it again, the wallbox starts to charge with excess. Our hybrid vehicle can charge with a maximum of 3.8 kW.

Could it be a performance issue (since the new GUI requires more resources) or a thermal issue?

I was able to observe that the sensors are continuously connected at night. then disappear completely during the day. (we are currently in Croatia, with correspondingly high temperatures outside).
It definitely only occurred with the beta. If it is a hardware or range problem, I would have problems before because the conditions haven't changed.

Hi @Christian Lindermann , it is affected.

From the manual:

Note for Cerbo GX units built up to and including serial number HQ2207: The built-in Bluetooth connection is disabled when the internal CPU temperature exceeds 53 degrees C (influenced by load and/or ambient temperature). For reliable operation it is necessary to use a USB Bluetooth adapter. Devices manufactured later (HQ2208 and later) do not require an additional USB Bluetooth adapter. Note that this limitation does not apply to the Cerbo-S GX.

DVCC maximum charge current has weird impact on battery charge current!

First of all I don't know when this issue kicked in and I don't know if it is related to GX firmware or not. But nevertheless it needs to be noted somewhere in order to get started.

I've tested this with:

GX firmware v3.40~30, v3.40~29, v3.30, v3.33
Multiplus II Firmware V498, V510 (higher version IMO do not seem to have an impact on the issue according to the release notes)

The 3~ MPII system has a 1,6 kV PV inverter on AC out L3 which is not registered by the Cerbo. When doing the tests it was constantly running at maximum of 1,6 kV. The consumption was kept stable as well. ESS enabled with grid set point set to 0W. Dynamic ESS disabled.

At a DVCC maximum charge current of 95A the AC excess is correctly fed into the battery. But when lowering DVCC max current, the system starts to feed to the grid. See below one example with DVCC max current of 30A where 655W are fed to the grid although the battery charge current is well below it's max setting.

When changing the ESS mode to "keep batteries charged" the batteries are charged with the DVCC max charge current setting.

If you have a Multi RS and if that #53 happened when battery was 100% and if the battery is publishing a CCL of zero amps when fully charged, then that problem may be from elsewhere.

Hi @CM

Pretty difficult to achieve...

The local (VictronConnect) parsed info about power is almost instantaneous, because the way it is read and displayed. All local.

The VRM one, needs to be packed, sent over internet network, stored into a database, parsed back from database and displayed onto the webpage. Not to mention the trip back to you, over internet, for that info to be displayed on your webpage, its refresh time settings, etc...

Those things take time, at least a couple of seconds or sometimes more.

Meanwhile, the local status is changing, sometimes that big as you've said, especially with variable solar / shade conditions.

Hello Alex

Gracias for your input … but

I don’t agree, if I follow your analogy even the AC information should be wrong but that’s also parsed from local to web just like everything else datawise, disparity is minimal but for the solar total disparity is much , my layman computing says that the code can be told to speed up the transfer rate if it’s already designed to pull same network total power that the VE Can is showing from same source .

Today I have no comments on the current FW version. Rather, I would like to know something about the strategy of the new or changed GUI (V2.0).

While the old GUI still tried to display the actual structure of the systems, the new GUI, for example, summarizes the solar systems and no longer displays their actual feed-in position (AC-in, AC-out, DC) correctly, but only symbolically. The same applies to consumption, which is no longer displayed separately for (AC-in, AC-out).

This is completely ok for an overview, but in the detailed view I find a display of the actual structure and energfyflow much better.

So my question is: Are there plans to display the actual feed-in and consumption locations in the detailed view in the future, or should the current symbolic summary be retained?

What I attempted to do in GuiMods was to provide details for a tile in a separate page. When there are multiple devices contributing to the summary tile on the overview page, each is listed along with their contribution and connection if appropriate. In some cases additional gauges are shown so the information is displayed graphically rather than just a number.

In my opinion, this is not yet happening in gui-v2. Rather the drill-down pages link to the same information as provided in the device list. This really is not what a user wants to see especially if there are multiple devices contributing to the totals shown for that summary tile and also now that for example PV inverters and PV chargers are included in the same tile.

Had same thing from time to time. Rolled back to stable than back to beta and looks like problem fixed.

I also read on forum that it can be caused by not available free space on Cerbo
