18.2.9. Q9: When I type the IP address of the Color Control GX into my browser, I see a web page
mentioning Hiawatha?
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.
18.2.10. Q10: I have multiple Solar chargers MPPT 150/70 running in parallel. From which one
will I see the relay status in the CCGX menu?
From a random one.
18.2.11. Q11: How long should an automatic update take?
The size of the download typically is around 90MB. After download it will install the files which can take up to 5 minutes.
18.2.12. Q12: I have a VGR with IO Extender, how can I replace this with a Color Control GX?
It is not yet possible to replace the IO Extender functionality.
18.2.13. Q13: Can I use Remote VEConfigure, as I was doing with the VGR2?
Yes, see VE Power Setup manual
18.2.14. Q14: The Blue Power Panel could be powered through the VE.Net network, can I also do
that with a Color Control GX?
No, a Color Control GX always needs to be powered itself.
18.2.15. Q15: What type of networking is used by the Color Control GX (TCP and UDP ports)?
Basics:
• The Color Control GX needs to have a valid IP address including a working DNS server and gateway. By default obtained from
a DHCP server. Manual configuration is also possible.
• DNS port 53 UDP and TCP
• NTP (time sync) UDP port 123. NTP uses a pool of servers provided by ntp.org, so this will connect to a wide variety of servers.
VRM Portal:
• Data is transmitted to the VRM Portal via HTTPS POST and GET requests to http://ccgxlogging.victronenergy.com on port 443.
There is an option in the menu to use HTTP instead, port 80. Note that in that case it will still send sensitive data such as
Remote Console related access keys over HTTPS/443.
Firmware updates:
• The CCGX connects to https://updates.victronenergy.com/ on port 443.
Remote support and Remote Console on VRM:
• An outbound reverse SSH connection is made to supporthosts.victronenergy.com when either one, or both, of those features
are enabled. The supporthosts.victronenergy.com record resolves to multiple IP addresses, and the DNS uses Geo-Location to
resolve it to the nearest server. This outbound SSH connection tries multiple ports: port 22, port 80 or port 443. The first that
works is used, and in case it loses connection it will retry them all again.
• No port forwarding or other internet router configuration is necessary to use these features.
• More information about the Remote Support feature is in the next FAQ item.
• More information about troubleshooting Remote Console on VRM is in here: Remote Console on VRM - Troubleshooting [71].
Two way communication (Remote VEConfig and Remote Firmware updates):
• Pre-v2.20: Uses HTTPS (port 443) to the Pubnub servers
• v2.20 and later: connects to mqtt-rpc.victronenergy.com on port 443; and also connects to the mqtt{1 to 128}.victronenergy.com
server farm. See this document for more information.
