Getting real time data from GX without using VRM portal

I am looking to get real time data from the CCGX without using the VRM Portal.
Reason is that the internet here is not reliable and could cause issues.


* 2 each of 10 x 315W panels with SmartSolar MPPT 250/60
* 2 x Multiplus 3000
* 1 x Fronius 5000
* Color Control GX
* 24KW Li-Ion batteries

Reason i ask - i would like to be able to detect when power available is less than demand and shut off via smart switches the heavier using appliances such as the electric geyser, dishwasher, dryer, washer, compressor, pool pump

ie: Cloud cover suddenly reduces available power from the Fronius and demand would exceed the capacity of the 2xMultiplus 3000 (4200W). Say the Fronius is pushing out 5000W and demand is 6000W - meaning the MPs are supplying 1000W. Cloud cover comes along and reduces the Fronius to 1000W, which would result in the MP having to supply 5000W, which it can do for a few seconds, but would ultimately overload it. In this case, would need to react quickly and shutoff the heavier loads until stable sunshine returns.

is this possible?


(Edit: I should mention we are completely off-grid)

Allow Venus GX to reference Voltage on AC1. Also Generator recognition from Digital Multi

I have a Victron Venus GX representing an implementation in my motorhome, of a Multiplus 2 12/3000/70-50/120. Currently AC1 is set to Grid, and shows Watts, but does not include voltage. I would like to reference the inverter input which does record and display voltage, how do I make the Venus reference voltage as well?

I have another need, that is more complicated. AC1 is the input coming off my ATS. The Multiplus is also controlled by Multiplus Digital Control. In this setup AC1 can reflect utility or Generator. The Multiplus Digital Control knows when the Generator is supplying current, as it is tied to a dry contact that closes when the generator input is providing input. Is it possible for Venus to detect the generator active condition?

Altenator Power Generation on VenusOS and VRM

Hi there.

When I am charging batteries from the altenator, it shows the power going from the DC system to the batteries. This is shown as a negative number.

What this does on VRM is remove the watt hours from the consumption as opposed to being included as a generation. This means that the daily consumption isn't accurate when I run the engine.

Is it possible that when the DC power is negative, the system tracks the altentator power generation?

Data Logging on External card not working ? FW 2.60

Hi everyone ! Not sure if I am missinhg something or misunderstood the way the data logging works with the Cerbo GX FW 2.60 and external storage. As you can see, the MicroSD 32GB is perfectly detected, but no record seems to be stored on it


The data is correctly sent to the VRM portal every minute, so not sure if the SD card is automatically flushed when the data is transferred to the VRM.

It will be interesting having it also stored on the MicroSD, so the data can be analyzed with other tools.

Thanks, Michel

No data alarm. relays

I just got another "No Data Alarm"
This means my 4G router has to be reset....which for me means flying across the ocean or bugging somebody to drive 30 -50 minutes to my boat


is it possible to program one of the relays to reset when there has been a 'no data alarm"

I do think the Venus reboots after it can not get a connection? Can that be used with one of the relays to reset the router?.

Venus GX lose communication with Inverters (repetitive issue on different system for the last 4 months)


This problem has been happening to us relatively often in our sites for the last 3-4 months. At least 5 or 6 times, each time of different systems. Suddenly the Venus GX lose communication with the inverters despite the inverters are running and powering the load, there is no data on the remote console on the inverter side


How to solve the issue is quite simple, we reboot the Venus GX and straight away there is data on the console. So, seems like the problem is on the Venus device and not on the Inverters


Obviously, this is not something we can do manually every time that there is a problem and if there is no signal on site, there is no way we can solve the issue so I hope this issue is addressed on upcoming firmware updates.

All these GX devices are running v2.60 and the inverters on which this have happened were running different firmwares 475 and 430.

Is there any kind of watchdog feature that could reboot the Venus if it is not seeing data from the inverter? if there is not, I think that would be an interesting feature to add on. I am seeing this feature on the GX manual but I dont think this is what I am looking for:


Could this be a hardware issue? If we upgrade to the new Cerbo GX that has a more powerful CPU and more RAM, would it be less likely to get this crash? or might it be a pure software issue?

Convert CCGX sqlite3-database file larger than 500MB into xls-file via VictronConnect

I have here a sqlite3-database file, which comes from my ColorControl-GX device (logging on the SD memory card).
Now I want to convert the data from the database into an Excel-file. For this I use software "VictronConnect" in the current version 5.34 and proceed according to the following description (see section 5.5):

Now I get an error message that the database file is larger than the limit of 524288000 bytes, which is exactly 500 MegaByte (524.288.000 Bytes / 2^20 = 500 MB).
Enclosed some screenshots - with v5.33 also tried with the same result.

Is this an error in the "VictronConnect" software?
Or is it an error in the firmware of the CCGX (VenusOS V2.53) that files larger than 500 MB are created? Consequently, new database files would have to be created when reaching the 500 MB database size.

My question now is, how can I convert the sqlite database file >500MB into an Excel file?

Thanks in advance.

Best regards,

Anbei einige Screenshots - mit v5.33 ebenfalls probiert mit gleichem Ergebnis.

Handelt es sich hier um ein Fehler in der Software "VictronConnect"?
Oder ist es ein Fehler in der Firmware des CCGX (VenusOS V2.53), dass Dateien angelegt werden, die größer als 500 MB sind? Hier müssten folglich beim Erreichen der 500MB-Datenbank-Größe neue Datenbank-Dateien angelegt werden.

Meine Frage ist nun, wie ich die sqlite-Datenbank-Datei >500 MB in eine Excel-Datei konvertieren kann?

Vielen Dank im Voraus.

VRM downloaded xls data; the counters data has many "a163" special events recorded

I have a Venus GX and download data every month in XLS format. I have activated all 5 digital counters and have "always" over two years, get extra data events which show all rows blank but add "a163" data in one column for each of the 5 counters, without affecting the data in any of the counters after.

My theory is for some reason the Venus GX has some glitch which triggers an event (outside of the normal 15minute data)which has a timestamp and adds data (exports on the Comm data) from some register to the counters "a163" data column but no other data in any column except the time stamp.

The "a163" seems to be random, some days have no reading and others up to 10 or more. I have set data to record every 15minutes.

Any ideas as to the cause and solution?

I am using a color control GX on my boats system, it is connected to a 4G Wifi router, Since this week I notice quit high consumption of data, which could only be used by the GX! (4.5GB in 5 days!)

Could it be the new version 2.60 is using more data?

VRM load history gives false presentation and data.

Hi, Anyone other than me think this is a (huge) problem?

is VRM a tool for presentation of history?

I think yes, and a greate tool for system monitoring... BUT...
all data logged when cames to history and peak loads are close to useless...

The pictures below show a overload on a 90 kVA Inverter system!

Tell me... what can we use this pretty pictures for other than it fals give an impression that system has only a 10% of its max load ? :-)

Is it a feature? A bug? Even a analog, 1980 home entertainment system had Vue meters with peak hold function........ Most cheap multimeter has the function as well.

(And actually.,, the year 2013 Color control gx was able to log peak loads down to a secound peak easy. And also show it on the excel download.
we used it that time as documenting peak load ability. Not any more..
now days not even close to real load data is logged in venus devices...

yes, i know i have posted once before about it.That time on soc view.
But no more information about what is concluded.. Only recognised it may be a problem....

is it an design feature? A bug? if recognise its a fail, what is the plan?

the tool has been broken now for years. If use api to pull data, the data will be false, and not show actual loads and therefore not showing actual problems for a system.

Today we need 3. Part dataloggers to give a any realistic presentation of load to our customers.

any info from Victron ? Is it a recognised problem? If so, what is the plan, and when...

CANBus interface on GX
I have mainly a Victron system installed in a 5th Wheel RV; 1020W of Solar panels thru a 105V/100A MPPT solar controller, and a 12V/3000W/120A Inverter/Charger for shore side charging with a Bluetooth VE buss smart dongle. I installed it myself and used a MK2-USB to set up the Mulitiplus for the 500 Amps of AGM batteries I have. I also have a BMV-712 to monitor the system. I'm interested in upgrading to Lithium batteries and also adding one of the GX devices to be able to remotely monitor my system (I currently only use bluetooth locally).

I'm looking at Lithionics batteries, their internal BMS models have an output cable that supports RVIA RV-C and CANbus information, specifically it provides battery Voltage and Current data, battery Temperature and SOC data, remaining Ah capacity, desired charger state and charge specs, HVC and LVC status, total Ah capacity and current Power, accepts ON/OFF/Charge-ON commands and a few others. The link for the information specifications and protocols is here.

I've tried asking and looking around, but can't find anyone with answers. I would like to know if any of the Victron Venus GX or Color Control GX or Cerbo GX interfaces can accept this data from the Lithionics GTX12V315A batteries internal BMS using the CANBus data interface. And if all I would need is the Lithionics cable (75-H1FCR-CS2 Ampseal 8 Harness Kit), to plug into one of the GX's.

Also, is specific programming required for the GX?

Venus GX data modified on VRM?

Hi, I installed a Venus GX to monitor a solar system, it works very well and I found the problem... the customer was sucking -80amps @ 50v (yes 4kw !) using the system to make tea and toast at the same time !

The system overloaded and shutdown (funny that !) so it was maybe only at 4kw for 10-15 seconds.

The strange thing is... a few hours later I logged in and the -80amps was clearly depicted on the V/A graph, clear as day and a pleasure to see.

But when I go back in to show the customer the logging, the particular -80amps plot is not there anymore, all of the days data is there, I am familiar with logging software I have triple checked the dates, times etc, I have stretched out the data to the hour that it was covered in, I have downloaded and reviewed the xls file,

But there are no xls timing gaps, there are no graphical gaps, it is like the software has 'smoothed' the 10-15 seconds of -80amps down to a more consistent -10amps for that time of the day.

How I wish I had taken a screenshot.... and now I'm even questioning did I really see it !

NB the shutdown was an Outback Inverter so there is no Victron error log, likewise no low battery alerts as none were set.

Appreciate any comments.

Relays and Battery Data on Venus GX Disappeared

My Venus GX has been installed for 4 months and working perfectly - using both relays to switch generator and a pump. Until today...

First Issue: Now, for no reason, the relay setting has disappeared from the settings menu. And I have no access to see or control the 2 relays. Why would the settings for relays disappear from menu? Normally, even with nothing connected to the relay inputs, they showed up as a menu item.


Second issue: The main screen no longer shows data for battery levels, PV levels, DC current etc (but they do still show up correctly and update correctly in the device list page so it is receiving all battery and MPPT data as per normal). This happened at same moment that relays disappeared.


And Last issue: the VRM Portal is not updating data. The Venus GX is online, and connecting every 30 mins - so I can see it - but the last data is from 5 hours ago (when relays were lost)

So what has happened ? Is it software or hardware of the Venus GX device?

Basically only half of the system is now working and they are not related (ie. relays going missing are not related to the main screen missing the battery voltage)... So it seems like a a software failure?

Using latest firmware on all connected devices. Tried rebooting, unplugging power etc multiple times.

Any advice appreciated

How to get USB Venus-data tar file to unpack

I asked this in the modifications space earlier this week I wonder if it can be answered.

Referring to implementation notes it says:

Also if venus-data.{tar.gz,tgz,zip} is found on removable storage (usb stick, sd-card) when booting, it will be unpacked into /data. Implementation details in this commit. Added per Venus v2.30~28.

However this is not working for me in Venus os 2.53.

I have traced through the init.d logic.

Execution of either of the scripts:

  1. /etc/rc5.d/
  1. or /etc/init.d/ 

Works fine and reports: "Updating /data with /media/sda1/venus-data.tar.gz"

And the contents are correctly installed on /data

But this is not happening when rebooting.

What am I doing wrong?

More diagnostic information is in my post in the modification space.
