To solve the problem, first find out how the system is connected, and then follow the right step by step instruction below. There are two ways to connect a Multi/Quattro system to a Color Control GX. In most systems they will be connected directly to the VE.Bus port on the back of the CCGX. And, option two, in some systems they are connected to the Color Control GX using a VE.Bus to VE.Can interface.
There is no 3G modem in the Color Control, and therefore also no slot for a sim-card. Go to a local store and buy a 3G router with Ethernet ports. More information in the blog post link below and particularly in the comments section, as more users try differing equipment:
Note that it is not possible to use a VGR2 or VER for this. Also it will not be possible in the foreseeable future.
No. Also, instead of this combination, we recommend to use the Color Control GX, and add a 3G or similar mobile router. See the Internet Connectivity chapter in the CCGX manual.
The general answer is: the Multi and Quattros are not measurement instruments, they are inverter/chargers, and the measurements shown are a best effort delivery.
In more detail, there are several causes for measurement inaccuracies:
Notes for systems with multiple units in parallel:
Tips to prevent measurement problems:
A VE.Bus system can be completely turned off, including its communication. If you turn a VE.Bus system off, and thereafter reset the CCGX, the CCGX cannot obtain the detailed product name and shows “Multi” instead.
To get the proper name again, go into the Multi menu on the CCGX and set the Switch menu entry to On or in case a Digital Multi Control is present, set the physical switch to On. Note that when there is a BMS, above procedure only works when within battery working voltages.
If a CCGX ever saw a VE.Bus BMS or Digital Multi Control (DMC), it will remember them, until 'Redetect system' is started from the CCGX menu.
After a minute, restart the CCGX: Settings → General → Reboot.
Our plan is to at least run a website where you can change settings and see the current status. If all works out as we would like to, there might come be a fully functional version of the online VRM Portal running locally on the Color Control GX. This allows people without an internet connection, or an intermittent internet connection to have the same features and functionality.

The size of the download typically is around 90MB. After download it will install the files which can take up to 5 minutes.
It is not yet possible to replace the IO Extender functionality.
Yes, see VE Power Setup manual
No, a Color Control GX always needs to be powered itself.
Remote support (default disabled):
Two way communication (Remote VEConfig and Remote Firmware updates):
MQTT (default disabled):
Remote Console on VRM (default disabled):
Remote Console on LAN (default disabled):
Modbus TCP (default disabled):
When enabled, the Color Control will open a SSH connection to our secure server, with a reverse tunnel back to the Color Control. Through this tunnel, Victron engineers can login to your Color Control GX and perform remote support. This works when the Color Control GX is installed on an internet connection. The connection will even work when installed behind a firewall. The SSH connection will be outbound, to port 80, 22 or 443 at supporthost.victronenergy.com. Remote support function is by default disabled.
Data usage depends heavily on amount of connected products, and behavior and usage of those products. The measurements below are an indication only, and taken from a system with one Color Control GX, one Multi, one BMV and one MPPT. Log interval set to 15 minutes. If you are on an expensive data-plan, do make some fail-safe.
Data consumption per month:
Mentioned megabytes do not include the download of a Color Control firmware update. Firmware updates of 60MB are not uncommon.
The current maximum is 9 sensors (since CCGX v1.31). Note that each need to be configured separately with an assistant in the Multi or Quattro to which it is wired.
If you power the CCGX from an AC adaptor connected to the AC-out port of any VE.Bus product (Inverter, Multi or Quattro), then a deadlock will occur after the VE.Bus products are powered-down for any reason (after any operational fault or during a black start). The VE.Bus devices will not boot-up until the CCGX has power …but the CCGX will not boot-up until it has power. See FAQ for more information about this.
This deadlock can be rectified by briefly unplugging the CCGX VE.Bus cable at which point you will observe the VE.Bus products will immediately begin to boot-up.
This deadlock can be avoided in two ways:
Cutting/Removing pin 7 of the VE.Bus cable to the CCGX (brown/white according to standard RJ45 ethernet cable colour coding) allows the VE.Bus products to start up without waiting for the CCGX to boot up first.
The disadvantage of cutting pin 7 is that switching the VE.Bus device off will be less effective: although it will stop charging and inverting, it will still be in standby mode and therefore drawing more current from the battery than if pin 7 had been left in place. Typically this is only relevant in Marine or Automotive systems where it's normal to regularly switch the VE.Bus device off. For those types of systems we recommend that you do not cut pin 7, but simply power the CCGX from the battery.
Yes you can! We intend to release almost all code as open source, but we are not that far yet. What we can offer today is that many parts of the software are in script or other non-precompiled languages, such as Python and QML, and therefore available on your Color Control GX and easy to change. Root password and more information is available here.
Typic the following address into the web browser of a device connected to the same network. Using this address as a template: http://[ip-here]/logo.php (inserting your device’s IP address between the square brackets). The IP address can be found by going to Settings > Ethernet or Wifi. Once the page is loaded, Choose an image file from your device. Re-boot the Venus-device.
Please check the remote switch connection on the Multi control PCB. There should be a wire bridge between the left and middle terminal. The CCGX switches a line which enables the power of the Multi control board. After 10 seconds this line is released and the Multi should take over from there. When the remote switch connection is not wired the Multi is unable to take over it's own supply. The CCGX will retry, the Multi will boot and after 10 seconds stop, and so on.
