Venus command-line manual

1. Introduction

This page explains how to change settings and/or update firmware for various Victron products which are connected to a Venus device, for example the Color Control GX, via the command line, ie ssh.

For more software developer oriented command line tips & tricks, see here on the Venus wiki.

Note regarding support: this document is made available for convenience only. There is no guaranteed support on this type of using our products: using the command line is outside normal use.

1.1 Use a normal tool instead of the command line

It is not at all necessary to use below command line instructions. We have far easier to use normal computer applications available:

VE.Bus products (Inverters, Multis, Quattros)

Changing settings with products featuring a VE.Bus comm. port (Inverters, Multis and Quattros) is normally done with VEConfigure.

Firmware updates are normally done with VEFlash, a computer tool that is installed together with VEConfigure.

To change settings remotely, use Remote VEConfigure.

Remotely updating firmware of a VE.Bus product is only possible from the command line, see below.

VE.Can products (Skylla-i, MPPT Solar Charger 150/75 & 150/85, and other products)

Updating VE.Can connected products is done with VE Power Setup, see VE Power Setup manual. Both for a local update, as for a remote update via the internet.

Changing settings of a VE.Can connected product (except for the Lynx Shunt VE.Can, which can be altered on the Venus GUI, and of course then also via the d-bus from the command-line). Normally done on the LCD panel of the product itself.

VE.Direct products (MPPTs, BMV, Phoenix Inverter VE.Direct, and other products)

Both firmware updating as well as changing settings is normally done with VictronConnect.

It is not possible to remotely change settings. Neither from the command line.

Updating firmware remote is only possible from the command line, see below.

1.2 Connecting to the command line and file transfer

See the ccgx root access page for an explanation on how to connect to the command line.

Besides accessing the command line, you might also need to send files back and forth. Use the Secure copy, or scp, for that.

2. Venus software updates

Check firmware version:

root@CCGX:~# cat /opt/color-control/version
Color Control GX

Then to update, this depends on which version you are running. Up until v1.74 we were using opkg package updates. And then we switched to image based updates, and jumped with the version number to v2.00.

See normal user documentation for how to update from v1.74 (or earlier) to v2.00 (or later). It is not possible to that remotely or from the commandline.

2.2 Venus v2.00 and later

Checking for updates and triggering a new update is all done with /opt/victronenergy/swupdate/

For an introduction, run -help. For more details, read its code.

2.3 Venus v1.74 and before

Updating Venus version

To trigger an update check, run:


If there are new updates found, and if the GUI is running and automatic updates are enabled, the GUI will automatically initiate an update followed by a reboot. Otherwise, trigger the installation yourself with:


To change the Update-to setting, use

Automatic update setting

To check if the device is configured to automatically update, query /Settings/System/AutoUpdate

dbus -y com.victronenergy.settings /Settings/System/AutoUpdate GetValue

The response will be either:

Status Meaning
0 Automatic updates are disabled
1 Automatic updates are enabled

To change the setting, simply do the following (replace # with either 0 or 1):

dbus -y com.victronenergy.settings /Settings/System/AutoUpdate SetValue #

3. VE.Bus products

3.1 Changing settings

Step 1. Reading the settings

To read the settings use:

/opt/color-control/mk2vsc -r  -s dbus://com.victronenergy.vebus.ttyO1/Interfaces/Mk2/Tunnel

-s specifies the serial port to use. In the above example we use the DBus MK2 tunnel. This is available when the vecan-mk2 service is active, which it normally is. For a direct connection use -s /dev/ttyO1

Optionally -f can be used to specify a custom file name to write the settings to

The generated file (.rvsc or .rvms) can be opened and edited on a PC using VE Configure

Step 2. Modifying the settings

Transfer the file to a computer running Windows, and which has the VEConfigure toolset installed.

On that computer, open the file by double clicking it, make the modifications, and save the file again.

Then transfer the new file back onto the Venus device.

Step 3. Writing the new settings to the system

To write the settings use:

/opt/color-control/mk2vsc -w  -s dbus://com.victronenergy.vebus.ttyO1/Interfaces/Mk2/Tunnel

3.2 Updating VE.Bus firmware

Requires Venus v2.00 or later.

Using the vbdup tool. This can update firmware of the following products:

  • Multi versions 26xxyyy/27xxyyy (minimum originally installed firmware, yyy needs to be 2xx or higher)
  • MK3

Updating other VE.Bus devices, such as the VE.Bus BMS and Digital Multi Control panels is not possible with vbdup.

Make sure that the Venus device (fe. CCGX), nor the routers or any other used communications equipment, is powered by the VE.Bus devices. If they are, you'll lose power and connection as soon as the update is started, resulting in a dead system.

The product that you want to update needs to have application firmware running: just bootloader is not enough. The update starts with requesting the hardware IDs (VE.Bus discovery) from the running application. Those hardware IDs are then used to address the VE.Bus devices once in bootloader mode. After the discovery, the hardware IDs aare stored in a file. In case, for example because of a power loss, the update fails, vbdup will automatically use the hardware IDs stored in that file.

Read the console help before use:

root@beaglebone:~# vbdup --help
vbdup version 0.05

Vebus device firmware updater.
Supported products:
  -Multi versions 26xxyyy/27xxyyy
   where yyy >= 2xx

   Updating will reset any user defined settings to default!

   If you want to keep your settings you must use VeConfigure, local or remote, to readout and save the settings.
   After updating, you can use VeConfigure again to restore the settings.

  Firmware updates currently do not work through the dbus tunnel. Please close the vecan-mk2 before using this feature
  Note, When updating to Multi firmware version 4xx
   Serial numbers where introduced with Multi firmware 4xx.
   In VEFlash the user is requested to enter the serial number manually.
   This code has no user interaction. We do not know the update order when multiple Multi's are connected.
   Therefore the serial number will be generated using the unique target ID
   Serial number format = tid######## where ##.. is the hexadecimal representation of the unique target ID.
   Existing serial numbers when updating within the 4xx range will remain unchanged


  -f, --file
   vff/vfd vebus device firmware file.


  -h, --help
   Print this help.

  --log-before <count>
   When set to non zero <count> number of log lines, which are
   not enabled themselves, are nevertheless shown before an
   log which is enabled. For example an error message will be
   preceeded by <count> warning and info messages which occured
   before the error. Combined with -v also warning messages will
   be preceeded by info messages

  --log-after <count>
   Like -log-before, but temporarily enables tracing of disabled messages
   after a warning or error occured.

  -s, --serial
    the serial port to use (default /dev/ttyS0).

  -i, --use-host-io-lines
    Use host processor IO lines to control MK2/MK3 reset and VE.Bus standby.

  -v --verbose
   Enable log messages. Specifying multiple times increases verbosity.

Victron Energy B.V.

Prior to updating a Multi the vecan-mk2 service should be stopped:

svc -d /service/vecan-mk2

To update run:

vbdup -f 2610408.vff -vvv -s /dev/ttyO1

-vvv is not required and only included to output messages on the console in order to see the tool at work.

Start the vecan-mk2 up again by:

svc -u /service/vecan-mk2

4. VE.Can products

First simply run vup to see connected products, and then follow onscreen instructions. No need to stop the canbus service, you can run an update, and when done, it will automatically recognize the updated product.

root@bpp3:~# vup
Querying devices
| NAD  | man | serial              | boot   | bmode| vup| vup#| id   | description                      | version  |
| 0x20 | 358 | 0013122             | 1.02   | -    | +  | 0   | 100  | BMV to NMEA2000 interface        | 1.06     |
| 0x20 | 358 | 0013122             | 1.02   | -    | -  | 1   | x    | x                                | x        |
| 0x24 | 358 | 0013463 HQ1227H7JSJ | 1.00   | -    | +  | 0   | 108  | BlueSolar Charger MPPT 150/70    | 2.02     |

To update the first device in the above list, use the following command:

vup -n 0x20 -f new_firmware.vup

For other devices, change the address, as found in the first column (NAD).
The name of the firmware file depends on the product.
E.g. skyllai_control_v1.10.vup for updating a Skylla-i Control to version 1.10.

4.2 Restoring VE.Can products to their defaults

WARNING: for chargers etc this is a bad idea to do remotely if you are not sure what you are doing, since charge voltages etc might be reset as well. It needs a ccgx version >= 1.30. -n is address, the same as for vup, see above (and just type vup to get it).

vreg -n 0x24 -s 4

4.3 Restarting a VE.Can device

A bit of a trick: below code first sets them to bootloader mode, and then back out of it:

root@ccgx:~# vup -n 0x24 -u
Querying devices
Found device, enabling UDF.
UDF is ready to accept update.
Udf enabled, update can begin.

root@ccgx:~# vup -n 0x24 -e
Querying devices
Update end send

5. VE.Direct products

First make sure to stop the serial starter:

svc -d /service/serial-starter

List all services running:

svstat /service/*

Look for the product you and to update, and stop that service as well:

svc -d /service/vedirect.ttyO2  (for example)

Then update the product:

root@bpp3:~# dup -s /dev/ttyO2 -f filename.dup
VE.Direct Updater
Updating device on /dev/ttyO2
Locating device
Found BlueSolar Charger MPPT 75/15 (A042)
Retrieving calibration data
Found application v1.14
Entering bootmode
Found bootloader v1.01
Erasing device
Starting new firmware
Verifying new version
Found bootloader v1.01
Update successful
Restoring calibration data


and when done, start the service and the serial-starter again:

svc -u /service/vedirect.ttyO2
svc -u /service/serial-starter

6. Screenshot

To make a screenshot press and hold the upbutton, and then press the down button. You'll then find /opt/color-control/gui/snapshot.png

7. Enabling Remote Console

If you have a CCGX already installed, but Remote Console on VRM is not enabled, follow these steps to enable it remotely:

  1. SSH into CCGX (make a root password by following instructions here)
    1. dbus -y com.victronenergy.settings /Settings/System/VncInternet SetValue 1
    2. dbus -y com.victronenergy.settings /Settings/System/VncLocal SetValue 1
    3. touch /data/conf/vncpassword.txt
  2. Reboot CCGX via SSH:
  3. Now you should be able to access Remote Console feature from VRM
  4. If you want to set a password, go to Settings → Remote Console → Enable password check

8. Enabling VRM two-way communication (Remote VEConfigure aka vrmpubnub)

If you have a CCGX already installed, but VRM two-way communication is not enabled, follow these steps to enable it remotely:

  1. SSH into CCGX (make a root password by following instructions here)
    1. dbus -y com.victronenergy.settings /Settings/Services/Vrmpubnub SetValue 1
  2. VE.Configure should now be able to connect to the CCGX
