For quite some time now [about once a month over the last 2 years, and almost 3–5 times a day over the last 3 months], my Cebro GX running firmware 3.75 has been losing its connection to the LAN/VRM portal. I connected a laptop to the cable and ran a continuous ping for 2 hours with 0% packet loss, so the line itself seems to be working. While the pings were running, I also connected the Cebro once, but it was unable to establish a connection.
What I find very strange is that, even though no LAN cable is connected to the Cebro, both LEDs are lit—is that really normal? The LEDs do go out “at some point”, but when I plug in a cable, they often stay off…
I will add, as a complete aside, that you have a VE.Can terminator in the spare VE.Bus port. Remove that; as detailed in the user and installation manual, VE.Can terminators are only to be used in VE.Can ports.
Yes! That’s a VE.Bus port, and must not have a VE.Can terminator in it. I don’t think that’s what’s causing your specific issue, but it can certainly cause issues in general, thus the warning in the manual.
With regard to your issue, I’d suggest taking the Cerbo out for a bit and double-checking the pins in the Ethernet port; hard to zoom in far enough, but those pins look a little funky, it’s possible that some corrosion or bent/crossed over pins or something could be causing the port to think something’s plugged into it.
About three years ago, I installed Node-RED – Venus Large OS because I wanted to write a “script” for the wallbox, but I never got around to it. In short, I only installed it and then never programmed or changed anything.
As far as I know, I haven’t connected any electricity meter…
In the configuration, I searched for energy meters, but none is listed there; there’s nothing under ModBUS TCP/UDP either.
Ethernet shows as “not connected”, so I’m using wireless instead, but the signal is extremely weak here. I’ve also tried disabling wireless and setting a static IP over the cable, but nothing has worked.
I don’t know, a tradesperson/electrician did it… maybe I don’t have an ESS, but according to Google’s definition of ESS, I seem to have that kind of system after all
Maybe the electricity meter is having connection problems and that’s why it isn’t showing up for me?!
There’s no documentation, and the warranty should still be valid. I had the system switched off for 8 hours, but unfortunately that didn’t help Ethernet now shows as connected, even when the cable is unplugged… Refreshing the window doesn’t change anything either, and the LEDs are lit. I’ve tried cleaning the port…
