Struggeling to set this up I have:

Ubuntu VM with a bridged adaptor on the same network as the CCGX.

I can ping the CCGX

Installed Node Red (https://nodered.org/docs/getting-started/raspberrypi ) got it running as a service and can view the flow editor.

Installed node-red-contrib-victron by doing steps 1,2 & 3 (https://github.com/victronenergy/node-red-contrib-victron#installation-and-usage)
Now I can see the Victron Energy tab

[image]

A CCGX with Modbus/TCP and MQTT turned.

Root password set and SSH'd into.

Carried out Step 4. (https://github.com/victronenergy/node-red-contrib-victron#installation-and-usage) - rebooted

Back on the Ubuntu VM

export NODE_RED_DBUS_ADDRESS=192.168.1.4:78 (the IP of the CCGX)

restarted node-red

But can't seem to see anything in the node-red editor.

What am i doing wrong? Do I need to generate the node specification file? (https://github.com/victronenergy/node-red-contrib-victron#generating-the-node-specification-file-developers)

Where do i get 2 .csv files from, I've tried just running (after installing csv-parse and gar via npm)

node parse-services.js --append

but it throws an error:

Please make sure that the files ./csv/dataAttributeEnums.csv and ./csv/dataAttributes.csv exist.

Hi,

I successfully enabled 3 additional relays on RPI running latest stable Venus OS but only first two are visible on GUI.

The other 2 are fully functional using CLI dbus Set/Get.

Is it possible to make them all visible on GUI and how?

Thanks,

Mihai

Hello

i use the Diplay Remote Console with raspberryPI, it is mount it on my Recreation Vehicule , it is only running with DC power

Is there a way to customize the Remote Console?

tks

I have a Raspberry Pi working well with Venus OS. I would like to control it from another RP. I have good WiFi or Ethernet to both. Is VNC the way to do this? If so how to I get VNC on the Venus OS RP?

Changes

General:

• Add "Inverter only" option to the On/Off/Charger-only switch in the Multi/Quattro menus
• Add support to give a custom name to our SmartSolar VE.Can chargers. Note that some other devices connected via VE.Can can also be given a customer name, such as a Skylla-i. But others unfortunately don't support that feature, such as our VE.Can Tank Sender Adapter.
• The "Multiple managed batteries" warning was removed, thanks Wilco.
• Send custom names to the VRM Portal. Soon we'll improve the VRM Portal to use those names, making it possible to customers to set their system up such that all those graphs on the Advanced page are named; rather than the "Solar charger (288)" naming.
• Fix issues related to DVCC and solar chargers; these issues were introduced together with the new features introduced earlier in v2.40 (charge current sense and more).
• Hide the bluetooth on/off switch on devices that don't have bluetooth. (the Cerbo GX has bluetooth).
• Fix bug where, in certain conditions, the Multi/Quattro could not be switched on.
• Fix bug that prevented disabling the Sunday in the ESS Scheduled Charging settings. Bug was introduced in v2.40~19, thank you John H for reporting!.
• Update VE.Bus Error 8 and Error 11 titles to be in line with the updated documentation.
• Add support for the Discovery AES battery, including forcing the DVCC & SVS options to their required setting (DVCC on, SVS off).
• Rename "Battery measurements" menu to "Marine MFD App Configuration" menu. Thank you Matej!
• Force the BMS-Can port on the EasySolar-II GX and MultiPlus-II GX to be able to be used only for that purpose, no longer as a VE.Can port. The reason why we changed that is that we can't guarantee proper functioning of that port for connecting VE.Can products, even worse: we know for sure it won't work reliable. The hardware is not good enough. Product documentation of those products has been updated already a while ago.

Developers:

• Change address of mqtt server. More info here. Note that, for now, there is still only one and the same mqtt server behind all those addresses. A few weeks from now we'll deploy the new cluster. After which still the old server remains in tact: any customer that has issues because of this change, and needs more time to adapt his own setup and software, can solve the problem by reverting back to v2.33.
• Cerbo GX preparations.
• VictronConnect remote settings preparations.
• Add ntp and gpsd as optional opkg installable packages

Hi has anyone got a clue how to connect the batrium bms to the ccgx, I have cabled it up, put in the correct resistors, gone through all the settings multiple times and can not see the bms on the device list. I have spoken with batrium (and apart from putting a new cable in, which I will do today) they were not a lot of help.

I would appreciate any help you can offer as I am about at the end of my patience :)

Hello

i am trying to do a SSH to the raspberrypi.. i am able to connect with my IP adress on the web, i see the remote screen.

i would like to connect with Putty.... the login as is what? what should i enter there? i try many name but cannot connect

Any help would be apreciate

So I finally installed my pi and touch screen in my camper van. Everything is working fine on the victron product side but when I went to disconnect my tank sender from the manual gauge to install on the Expander PI ADC board and it still said shorted. I couldn't figure out what was wrong, then I take out the voltmeter and found that the tank sender is a 0 empty to 90 ohms full.... *facepalm*. I bought my camper van from someone else and the sender was already installed and I just assumed it was a standard NA 240-33ohm sender. Instead of getting a new tank sender, is it possible to change the settings somehow on the Pi to read this tank sender?

At least the panel turned out well (looks like I can't upload any photos).

My system:

ESS configuration with grid meter.

ALL latest firmware.

RPi 3B+ Venus v2.33

SmartSolar MPPT 150/35

Multiplus 2 48/4000/35

DIY Lion Battery.

RPi -> Victron RS485 USB dongle -> ET112

All other connections as standard (mppt (VE.direct USB dongle), multiplus (MK3 USB dongle)).

So, all working fine for weeks. However, remote console this morning showed all devices detected apart from grid meter?

What are my options?

How do I check the RS485 dongle is working correctly, are there errors signalled by the flashing leds. No green leds are flashing just the red one every few seconds.

When I unplug and plug the dongle the green led flashes once and then the red led flashes 8 times then pauses then flashes 15 or so time? Any clues.

The ET112, seems to be fine but how do I test the data is being sent?

Have rebooted RPi, no joy.

Any ideas would be most welcome.

Instead of using an engine-driven alternator, I'd like to make use of the engine compartment's air in-flow to drive a wind turbine. I would think this might be more economical using a high quality Chinese made wind turbine generator; no air intake when vehicle is idling avoids alternator overheating issues. Has anyone done this or know how best to design such a solution to augment the solar charging of my 24v Tesla battery bank.

Hello

The VictronConnect is nice to have a look of the moment but for example

history over hours I cannot see...

My question now: Is the communication protocol public available?

I want to design an application for Arduino o rasp pi to collect data for statistics...

I'd like to reopen discussion on this topic. I'm a novice and freely admit that I really don't understand all aspects of how to get this to work. So I may be totally off with this so please correct me if I'm wrong. I've read this thread:

https://groups.google.com/forum/#!msg/victron-dev-venus/mejgJbMjU34/yogWAU5wCAAJ;context-place=forum/victron-dev-venus

I purchased the same board as what's here, the Expander Pi with the mcp3208 12-bit ADC.

From reading this, I'm a bit confused how to wire this up. In that thread, they point to the reference voltage of 1.8v. However the expander pi has a reference voltage of 4.096. But in other threads, they talk about a reference voltage of 5v. I also see the schematic of the BBB Cape and it says 5v as well:

[image]

I'm not sure what is correct or if the reference voltage even matters since both are 12-bit ADCs, the reference voltage shouldn't matter as it's just reading the resistance of the sender. But then I'm confused on how to wire this up with the Expander Pi. Anyone who has this board, would they care to share their setup, possibly with photos or diagrams? I'd appreciate it.

tagging @WKirby as you've always been super helpful!

Hi everybody,

I am currently setting up my RV with some Victron equipment (BMV, smart MPPT, etc) as a central element I use a pi with Venus OS.

My question is, is it possible to have Grafana/InfluxDB on the same device? I do not what to run a second pi just for that as energy consumption is always critical.

I am not a Linux guru and struggling installing the docker-composer on my Venus OS pi.

Thank you for any help and/or tips.

Cheers

Dirk

Hello everyone,

It seems almost any information a person would need from the Venus OS device is published to it's own local MQTT server. I have accessed that MQTT server from a client and was able to get voltages and other information out of it. The Raspberry Pi is connected to a Victron 100/15 SmartSolar via a USB to TTL adapter and I can access the information and settings for it from Venus so that is not a problem. I understand the Venus MQTT requires a keep alive message to be sent about once every 60 seconds. I also already run an MQTT server and Home Assistant on another Raspberry Pi that I use for everything else.

How can I get the data I want (or all of it) into Home Assistant? Preferably, I just need to get Venus to send the messages to my normal MQTT server instead of it's own, or maybe a script that subscribes to the Venus MQTT, publishes a keep alive once every 60 seconds, and then forwards all received messages to the normal MQTT?

Thanks for implementing battery current update in latest MPPT firmware version. It nicely complements allowing adaptive absorption time to be turned off (useful for my Lithium with very variable charge rates).

What response should I receive from MPPT firmware version 1.44 when updating the Battery Charge Current with Hex Protocol. Register is 0x200A

0x200A Battery charge current (*8) 0.001 sn32 A

I think I'm receiving "1" which looks promising but I'm more used to seeing the new setting echoed back to me when changing values.

Sent:- :80A200030F8FFFFFD which represents 2 amps.

Returned:- :80A200122

Does this response indicate update successful?

and how?

Thanks,

Mihai

Hi,

We would like to run some experiments with the MQTT service on Victron systems. Is there some sort of sandbox available that we can use? Thanks.

Cheers,

Imre

Hi,

the latest MPPT Hex Protocol documentation refers to Register 200C Device State but does not provide the accepted register values to represent Bulk, Absorption, Float.

What are they?

Thanks

Hi all,

To address a soon coming broker (over-)load issue, we are changing the address of mqtt.victronenergy.com broker. The change will be deployed as part of v2.40; planned for release within a few weeks.

See changes in the dbus-mqtt readme for what has changed and what you need to do in case you are using this in your software projects.

I have a Skylla 24/100 which I used with my old 24V Lead Acid system. I have changed to a 48V 10kWh BYD battery system with a Multiplus 48 / 5000 / 70.

I see the PCB in the Skylla 24/100 is common to 24 and 48V with a link component to activate the relevant version.

Is it possible to move the link to convert the 24/100 to a 48/50 with relevant setting changed?

I have tested the login web service using postman and I was able to acquire the token.

I have tried authenticating with the api using a C# console application but it always results in 401 unauthorized with the error code : {invalid_credentials}

Below is the code sample:

var client = new RestClient(loginRequestIntegrationDTO.BaseUrl);

var request = new RestRequest(loginRequestIntegrationDTO.EndPoint, Method.POST);

request.RequestFormat = DataFormat.Json;

request.AddParameter("Username", loginRequestIntegrationDTO.Username, ParameterType.RequestBody);

request.AddParameter("Password", loginRequestIntegrationDTO.Password, ParameterType.RequestBody);

var apiResponse = client.Execute(request);

Any reason why i cannot connect through the application ?

To use the Tank (or other relays in the MultiPlus-II GX, you shal go to "Relays" in the menu. I can't find relays in the menu..

Is there any way to edit existing or even create new assistants?

I've got my Quattro starting and stopping my Onan Generator (that uses 3-wires) based upon the suggestions here https://www.victronenergy.com/live/auto-generator-start-stop:start using K1 and K2 relays, however, the generator start-stop assistant looks to be more flexible but of course only operates the single relay.

Hello,

I am have downloaded and installed the Venus OS packages onto Raspbian and they seem to run OK.

I also want to get a GPS I have (ttyUSB1) connected to the Rpi to parse data to the VRM portal. There is no instructions for this on the packages website.

Does anyone know how this is being done? Is it via D-bus somehow?

If someone could at least steer me in the right direction I might have a hope of getting this to go.

Thanks

Al

Hello

It is possible to have the Victron console on a screen without wifi or land?

My raspberry is running, I could connect to it with my hotspot but sometimes where I go there is no cellphone signal.. I would like to see the console on a screen add it to the raspberry

We are trying to read the 75/15 with current firmware through the hex protocol. The txt protocol shows all values in the correct manner, but when we read the values through hex it is totally messed up with senseless values with correct checksum. Eg yield today is 6 times higher than it is shown in connect.

is the manual wrong in terms of the number bases like uint16 etc?

If we read a bmv every thing is fine with the same codebase.
