Hi,

I'm used to work with Venus on RPi, but now I have got a Venus GX and I can't figure out how to set a password for the root aacount so that I can access the GX over SSH/ SFTP to install a SSH key.

According to the guide here: https://www.victronenergy.com/live/ccgx:root_access#create_a_root_password it should be possible to set in the remote console but I¨m not able to find the menu Settings → General → Set root password.

I have tried to connect a USB keyboard to the GX, but it seems that the keyboard doesn't work on the GX.

I have updated the firmware to v2.40~35.

Can anyone guide me how to set the root passwordor maybe a Victron Tech can set it for me?

Hi

Does anyone know what GPIO ports are used for the digital inputs and for the relay outputs on a RPi to replicate the functionality of a real Venus?

I've trolled through all the sites I can think of and come up blank. Anyone cracked it?

Any guidance greatly appreciated.

Cheers

Phil

UPDATE 2019-10-11: Earlier I wrote that one can now set input current limit *and* control on/off/charger only with a VE.Bus BMS, but thats wrong: input current limit works. Changing between on/off/charger only is still not possible for installations having a VE.Bus BMS. Apologies!

Hello all!

Its been a while, but we've not disappeared ;o). This is the first time to make v2.40 available for testing. It brings lots of changes and features, a few large and many small ones. There are several gems in there. For example that now shore current limit can be set for systems with a VE.Bus BMS (yeah!). Also it simplifies installing a system with a BYD battery by setting the DVCC and SVS config options automatically as well as forcing them in the known good position. And F I N A L L Y: it transmits data out on the NMEA2000 network. For now, it transmits battery monitor data. Inverter/charger data will follow asap. And then many many more changes. Better get a cup of tea of coffee and then sit and read.

I must say that for many of below I had a hard time writing them down in a concise manner, if you see any improvements on the text, welcome to post below. It will all end up into the official changelog & blog post.

Lastly, if you don't know what this post is about: this is about our GX Product range, and this post is aimed at all the members of the Beta test group. See this information on how to join (and leave) that group is here.

Enjoy the testing. If you see any issues, please post below. Thank you.

Change log

Inverter/charger monitoring & control

• Better support systems with a VE.Bus BMS. It used to be impossible to control the input current limit on a GX Device. Now, as long as the Multi or Quattro is running 415 or newer firmware, this control is available. Switching between On/Off and Charger-only is not possible.
• Add Grid failure aka Shore disconnect detection. When enabled, an alarm is raised when the system hasn't been connected to the AC input defined as Grid or Shore for more than 5 seconds. The alarm shows as a Notification in the GUI, as an alarm on the VRM Portal and is available on ModbusTCP / MQTT. Very nice for backup systems. But also for yachts or vehicles on shore power. Now its no longer necessary create a complicated custom alarm rule on VRM, monitoring Inverter/charge states. Note that this settings monitors that the system is connected to grid/shore. Generator monitoring is already available as part of the Generator start/stop function.
• Send the charger state (Bulk, Absorption, Float, Storage, Equalise) of inverter/charger to the VRM Portal, when in Offgrid mode and charging with power from a PV Inverter wired on the AC output side. Note that this parameter is not yet used on the VRM Portal website, but you can see it already in the CSV/XLSX download. This is useful especially for systems in Off-grid mode with PV Inverters on the output.
• Add VE.Bus network error counters. Useful to help troubleshooting vague VE.Bus Errors cq to rule out cable issues. Counter data is also available on VRM. Needs a document on explaining how to interpret those values.

DVCC & Scheduled charging:

• Scheduled charging: change the hysteresis on SOC when battery full from 0.1% to 5%.
• Complete support for the recently introduced VE.Can MPPTs. All DVCC control features were added: current and voltage limit control, as well as SVS, STS, and Shared Current Sense (SCS). With this change they are now fully functional also for ESS systems and systems with Managed Batteries.
• Add an option to send the battery current as measured by a BMV to the Solar Chargers. This goes hand in hand with a new feature in the Solar Chargers, to end the Absorption phase based on tail current, and then actual to tail current based end of absorption (primarily for lead batteries). This is part of DVCC, and only applies to systems that are not ESS (since then the inverter/charger manages the charge profile), and have a battery monitor such as a BMV-700 or Lynx Shunt VE.Can. Requires a Solar charger firmware version not yet officially released. Download the latest VictronConnect v5.12 beta to use & test this new feature.
• Add an option to use Battery Temperature as measured by a BMV, the GX Device itself, as well as a MultiPlus for other connected chargers: Shared Temperature Sense.
• ESS: use the Multi as source for Solar Charger voltage sense - always.

Managed Batteries (BYD, Pylontech, Freedomwon, and similar)

• Add capacity. Visible on VRM on the diagnostics page, and in the GUI of the GX Device
• Fix Freedomwon Lite recognition. They were being recognised as a LG battery, now as a Freedomwon Lite
• For BYD batteries, MG Energy Systems batteries as well as Victron batteries connected with a Lynx Ion BMS, eliminate the need to the installer to configure DVCC and SVS: they are now automatically set (and unable to change) to the required settings: DVCC=ON and SVS=OFF for both batteries. This will be a nice improvement in making it easier to install those batteries. We'll do the same for more battery brands later.

Other changes

• Add NMEA2000 out function: transmit battery monitor out on the VE.Can/NMEA2000 network so it can be picked up by Marine MFDs. Currently it only transmits battery monitor data. Inverter/charger data will follow soon. This is by default disabled, see Settings -> Services -> CAN-bus to enable it: (screenshot).
• Fix the Navico Fluid Level Sensor Fuel-0 PK, partno. 000-11518-001, not working. Broken in Venus OS v2.30.
• Support using a single-phase PV-inverter connected across a split-phase connection (no neutral). This is a common option in North America where a 240V or 208V PV-inverter is connected to a split-phase supply. Half of the Energy and power as reported by the PV Inverter is attributed to (reported on) L1 and the other 50% on L2.
• PV Inverters: add an option to disable automatic scanning
• Fix that Disabling the built-in WiFi Access Point also made the device to not connect to a WiFi network automatically as well. The workaround was to go into the WiFi menu, or (?) power cycle (I'm not 100% sure about this one). Now its fixed: disabling the built-in access point no longer affects how the device handles connecting to other access points.
• Restore relay state, when configured to be manually controlled, after a reboot. Rather then always resetting it to Open.
• Fix a mistake in the calculation behind the DC System box on the overview. The PV current was not added to the total, causing the value to be wrong. See "Has DC system" in the manual to see what the DC System Box is about.
• Fix bug that prevented setting entering certain IP Addresses. Thank you ScottB for finding this.

Added the IMT Solar Irradiance, temperature and wind meter

Looking for a good way to measure solar irradiance, we tried different meters, and eventually chose the professional irradiance meters from Mencke and Tegtmeyer GmbH in Germany. The type of meter supported are the Si-RS485TC series. They also feature an optional temperature sensor and wind meter. Connection to the GX device is done using our RS485 to USB cables.

Here is how the data is show on VRM. Note that this test system is currently still indoors, not much to see.

And here is how its visible on the GUI:

Clean-up of the System Setup and DVCC menus

The System Setup menus was becoming long and cluttered. Now there are two menus, all DVCC related features are in a separate menu. For those not familiar with DVCC: that setting changes the GX Device from a passive monitor, that takes data and makes it available for monitoring and analysis, into a active controller, that optimizes the charge process by taking control and sharing data between the connected devices. More info in the DVCC chapter in the manual. We do have some more textual and UI changes planned for that, later. For now, these screenshots show current status as in v2.40~34:

[image]

[image]

ModbusTCP

• Add menu to see last issues (screenshot!)
• Add Grid Loss alarm register (830)
• Add support for the EasySolar-II and MultiPlus-II GX by mapping the vebus service to unitid 228

MQTT settings cleaned up

• The previous setting, MQTT on LAN has been renamed to "MQTT on LAN (Plaintext)". There is a new setting called "MQTT on LAN (SSL)". The difference between Plaintext and SSL is just that: enabling the plain text one opens it on port 9001 (MQTT over websockets) and on port 1883 (pure MQTT) and the SSL one opens the encrypted variant of that on port 8883. Whats also new is that its now possible to enable MQTT for use on the local LAN, without also enabling the uplink to our cloud broker, which often was required. After the update, settings of existing systems are migrated such that nothing breaks. For details, see here: https://github.com/victronenergy/venus/issues/480.
• The very rarily used and specialty service 'NMEA2000 on MQTT' is now hidden under the superuser access level: we saw far too many people that had enabled that while they don't use it. And it increases CPU load.

Hello

How to have the data from the smart battery sense for my Starter battery on the VRM Portal

I Create a VE. Smart networking

- BMV-712 + Battery temperature + Smart Solar + Smart Battery sense (Starter Battery)

My Setup

Victron Image = 2.33

Raspberry 3 B+

Window PC

-Victron smart battery sense for my Starter battery

-Victron BMV-712

-Victron Smart Solar Charger MPPt 100/50

All

Everything works when connected, I see all those on the iPhone app bu cannot see any information from the VRM for the battery sense

Did I bought a battery sense for nothing :-(

I have successfully connected my Venus OS on a RPI to an MPPT 100/30 and am Transmitting data to the VRM on Victrons servers.

The environment is a Van / Motorhome
I have a MPPT 100/30 (non-bluetooth) and a BMV-712 (Bluetooth) plus a Victron Smart Battery Monitor (Bluetooth)
My understanding is that I can get another USB connector to plug into the BMV and the RPI and that will give me SOC of the battery
However, how could I measure temperature ?
My Smart Battery Sense measures temperature of the batteries and transmits it via BT

Is there ever going to be an integration of the VE BT Network into the Venus OS on the RPI ?

Is there anyway I can obtain the temperature information from the Smart Battery Sense and transmit it to the VRM ?

Thanks

In the buffer i got values that can´t convert to text or hex, [98 63 65 -128 3 0 -94 ....]

Somebody knows some Java/Android reading example?

Thanks in advance.

I had Consumption showing on my RPI 3B+ system, and then it disappeared. Not sure why.

Can anyone suggest what I could have changed in my configuration to lose this useful display?

Configuration

RPI 3B+ Venus OS 2.40-22

REC-ABMS for Victron GX CAN

The MultiPlus 12/3000/120-50 is still in shipping, so I have not connected that at all yet.

I do have the USB MK3 adaptor installed though, nothing attached to it.

Any ideas please?

My raspberry receives data via VE.Direct from the charge controller, but I am unable to format it in a readable format. Actual output is [98, 65, -128, 68...] ¿some idea, please?

I want to set up a system with two Quattros working in parallel. I set up in the VE.Bus configurator the 1 phase system with these two devices working in parallel. I just have AC-In 1 so AC-In 2 remains unconfigured. Nothing is connected to these inputs.

[image]

Then I configure each inverter and I expect them to built the grid (I have a generator in automatic mode, just for back up). This is the line diagram of the system:

[image]

For some reason switches I1 and I2 are switching off. The only way I can make both Quattros work together is to open either I1 or I2. Voltage of Q1 is 10V higher than voltage of Q2.

Moreover Q1 shows fix "inverter on" led while Q2 shows "mains on" and "inverter on" blinking simultaneously.

Thanks in advance!

Hello!

Has anyone had any luck getting Venus (OS) images booting, or the VRM reporting packages running on a NanoPI? I just tried flashing the latest nanopi images but it doesn't pull a DHCP address, looking to attach a console cable and see where it's failing.

For Victron Staff,Is possible to the next upgrade to on Remote console , to see the K1,K2 Aux .. Status? At the moment is not possible to se the status of Aux And Relay .Also is possible to see On VRM the Inverters status Aux and Programbile Relay status?

Its not possible to change

DC input low shot-down to 37 V, and

DC input low restart to restart to 37,5 V.

Can i send the file to Victron to get this done?

Email, website?

Im using two Tesla battery modules Li-ion 6s 24V in series (48V) and the span for these are max 50V and min 30V if im correct.

Thanks for any help!

i have two 90ah life04 batteries and want to add two 100ah in parallel to obtain 390ah is this ok to mix different ah life04 batteries

Has anybody every customised the main page of their CCGX? From reading a few articles, it appears that it is possible (though people seem to customise the Venus GX). Any particular articles that walk through the steps/tips? I have a (Linux) software background, so it should be doable for me.

Specifically, most of the screen real estate is being wasted, as this ship does not have an inverter, and thus the top two thirds of the screen are always blank. Ideally I would like to:

• Expand the DC Power block to include a current figure.
• Add a block for the engine alternator, and show current flow from it.
• Display the AC current being fed from a generator.
• Display the AC current from shore power.

Is there any mechanism to display current/voltage data from external sources on the CCGX?

Thanks,

Allan.

Any way to combine irradiance data to VRM?

Which sensor?

Hello,

i would like to know if the future release of venus gx will integrate a set up to have the right level on the real time of the water tank.

For your information:

When i fullfill my water tank, i realized that the level doesn't appears in the real time. I took the Venus GX because there is this option (3 tanks sensors) and i realize it doesn't work. It is really dangerous because if i doesn't stop the fufill at 80%, i would have had a flood in my camper van. The level had appears to 100% few minutes after !After look for this problem in the forum, it appears that i'm not alone, apparently there is a averaging of the value which create a wrong value in the real time.

thx

Hi,

I've found the connector for remote control of the inverter, terminal L in manual, where I can set the state of the Quattro remotely. But I'm trying to find a way to also show the state remotely. Is there a clever way to get an LED to light up on a remote cable when the inverter is on?

Background:

I'm building a remote control for the Quattro on my boat and is looking to build a three-state-switch on the control panel of the boat. As it is an old boat I want to hide as much tech as possible. I'm looking to make the states of the switch off-auto-on, so that if I set the state to off it will not turn on inverter, in auto it will turn on whenever I have either more than 90% battery or the batteries are charging and in on it will turn on the inverter.

I have figured out how to do most of these things. I'll use the L-terminal to remotely control the inverter and I'll probably write a small python script which will close the relay on the Color Control GX whenever I'm charging or have more than 90% charge so that in the auto-position of the switch it uses the relay as switch. The thing which is left is to indicate the state. I want to show with an LED next to the switch if the inverter is running. Currently the only ideas I have is either to hide a 5V USB power supply in the inverter, connected to the AC out which will supply power whenever it is on, or to hack the LED on the Quattro and solder an extra cable onto that inveter-on-LED-indicator.

Ideas welcome!

Hello,

recently I have bought the Venus GX and was pretty disappointed of the overview pages. Since I only have a BMV-712 and a MPPT Solar Charger the overview pages does not fit my needs. Therefore, I have changed some "qml" files of the QT gui to get "my overview". My BMV-712 and the MPPT are connected with VE.direct to the Venus GX. The overview displays all (for me) important information now on one page. My overview are displayed as follows:

[image]

Maybe, this qml changes are useful for anyone. The file needs to be overwritten at the directory "/opt/victronenergy/gui/qml". However, never forget to make a backup before and do this on your own risk! My overview replaces only the file "OverviewTiles.qml" and added two own format style files. Please notice, if you run the same environment and want to use this, you need to check the VE.direct are setup in the correct order to the Venus GX ("com.victronenergy.solarcharger.ttyO2"/"com.victronenergy.battery.ttyO4"). Check the connectors and switch them until it works, or change the source code of the qml file. Afterwards, just reboot the Venus GX.

Might be helpful, and give some ideas what is possible. Use it on your own risk! This is just a demonstration example which works perfectly for my use-case! Victron should consider to add more specified use-cases the the Venus GX pages (and feel free to add this overview for people only using MPPT and BMV)! Finally, on every update of the Venus OS, the files needs to be recopied - and maybe updated/adapted again!

Hopefully this is useful for anyone!

I would like to create my own automation hardware/software for the BMV-700. Is the communication protocol for bluetooth available for me to use?

RE Tank setup: My domestic freshwater tanks are 42000 litres which required the setup + button to be depressed for some 10 minutes to increment to 42000. It would be helpful to make large reading easier/quicker to input.

My tank sensor is a pressure sensor 4-20ma, which is common for a range of sensors. Could you give consideration to interfacing 4-20ma sensors to the Venus GX?

With the use of 4-20ma sensors would also require the calibration of the upper and lower settings in the digital set up within the Venus OS. Currently, I need to design an additional circuit to interface with the 0-180 ohm settings for the 4-20ma sensor I have. Has anyone such a circuit?

Keep up the good work on your products.

Since the CANvu has been released, is there any chance we can run the Pi with the official 7 inch touch screen at higher resolution? There aren't any specs of the CANvu screen, but it at least looks 16x9. Thanks!

Multiplus II GX connected to Liion Battery. ESS activated. Only AC-IN connected, no AC-Out

When ESS in "optimized" I can set the grid point with register 2700 on ID 100.

When setting ess to "external control" (aka Mode 3?) the Multiplus goes into ESS passthru.

On top of that ID 242 / 246 is not readable (registers 37/38/39).

They are also not readable in optimized mode and also tried reading them with ID 100. No chance.

I can write to them, but nothing happens.

Could not find in the latest register listing. As on previous post, I am wanting to control the AC out #2 on Multiplus 12/3000/120-50 120V.

Hello,

I'm playing some hours on the command line on the VenusOS 2.33. Because I'm working also as a penetration tester (ethical hacker) and there are some security issues I've some thought about the actual configuration. Unmodified operation in a professional management vlan is therefore not possible.

#1: One should be able to disable services not necessary in some environment, eg llmnrd, simple-upnp, avahi, etc.

In a clear designed system it should be able to do this with the command update-rc.d and remove the corresponding symlink in /etc/rc5.d/. But some services are started here via daemontools supervise.

My workaround for a clear design: I touched a down-file in /services/$SERVICE/ and wrote a simple script eg /etc/init.d/llmnrd-supervised which controls the service via the svc command. Then you are able to enable or disable this service with add or delete of the symlink in rc5.d/

#2: the transmission of the Remote Console password in clear text over port tcp/81 or no password is not state of the art in 2019.

With the change to the lighttpd webserver it would be possible to pass the websocket traffic over tcp/443 and anyway the initial login. And with lighttpd you can have more sophisticated authentication, eg GSSAPI.

Then the VenusOS and the connected stuff can be used to power a computer rack with green energy and you will have a secure setup up to date in 2019.

hi,

I try to understand the communication of Bluestar MPPT 70/15 with external microcontroller system (e.g. arduino) with hex protocol
I received some exmaple codes from open source page of victron.
But there is a main point that i could not understand.

i could not undestand the main message format such that:

get MPPT Charger Volt ":7D5ED008C\n"

: is starting colon

7 is get command

D5ED is adress of charger voltage 0XEDD5

008C what is this phrase?

\n add of command

another example:

get MPPT charger current ":7D7ED008A\n"

: is starting colon

7 is get command

D7ED is adress of charger current 0XEDD7

008A what is this phrase?

\n add of command

i think everything will be clear for me if i can learn this part.

best regards,

Hello,

The main page of my CCGX is showing AC input,AC loads, PV charger, etc.

As I don't have some AC components in my van, is there a way to get rid of them in this page? I have no use of seeing them.

Thank you.

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.
