Manually transferring datalogs to VRM
For devices permanently without Internet, it is possible to take the data out, and then upload it manually from a laptop.
1. go to Settings → VRM Portal, and click Eject the storage. Make sure to never just remove the SD-card/USB-stick, this can
lead to corruption and data loss.
2. now, remove the storage device and insert it into a computer or laptop that is connected to the internet.
3. open a webbrowser, and navigate to the VRM Portal.
4. Login, and then click the 'Upload GX file' option, and follow instructions:
5. Remove the file from the storage device, and then it re-insert it into the GX Device. Note that uploading the same data twice
does not cause any problems; but still it is better not to do that.
With a log interval of once per minute, the required storage space roughly amounts to about 25 MB per month, depending on the
number of connected products. So with a 1 GB microSD card, you can store about 3 years of backlog. In other words, any
microSD card or USB stick should be sufficient to store the 6 months of data which VRM retains.
When the storage device is full, no more data will be logged.
If multiple storage devices are inserted, the GX device will store the data on the one inserted first. When that is removed, it
will not use the other one. Instead, it will create an internal backlog buffer. Only inserting a new one will make it switch to using
external storage again.
Network watchdog: auto-reboot
This feature, disabled by default, makes the GX device automatically reboot itself in case it has not been able to connect to the
VRM Portal.
Please be careful with enabling this feature on ESS systems: when grid connection is lost, and the GX device reboots, the system
can lose power when rebooting takes too long (when grid is present, the Multi's or Quattro's will enter passthru).
9.4. Trouble shooting data logging
This chapter explains what to do when the GX Device cannot transmit data to the VRM Portal.
The communication required to send logs to the VRM Portal is:
1. Working DNS
2. Proper IP address
3. Working internet connection
4. Outbound http(s) connection to http://ccgxlogging.victronenergy.com on port 80 and 443. Note that should never be an issue,
unless on very specialized company networks.
Note that the Cerbo GX does not support a proxy setup. For more details on the required networking, see here.
Step 1: Update the GX Device to the latest available firmware
GX Device firmware update instructions
Step 2: Verify the network and internet connection
In the menu Settings → Ethernet or Settings → Wi-Fi, check the following:
