I think those are details you need from your sim card network provider.

The GX only needs to logon to the router; the router connects to the APN and gateway.

I dont know where you are but even google your network provider name followed by apn would help.

Hi @kaarthik

I doubt this is possible. The Cerbo GX does not support cellular modems other than the GX GSM or GX LTE 4G. See also the note here: https://www.victronenergy.com/media/pg/Cerbo_GX/en/internet-connectivity.html#UUID-39ca5504-f0b4-6230-5d42-00317bd55afe

So you can choose between either a cellular router (not a modem) or a GX LTE 4G.

Hi @Stefanie (Victron Energy Staff)

Thanks for responding.

Here is what I have done so far.

1. I've set up a network using my sim card and a TP-link router

2. In this network, I assigned a static IP address to the Cerbo GX device using its MAC address

3. I created a white list for this network which includes only the Cerbo GX and my laptop. I confitmed this by trying to access this network with my cell phone and failing to do so.

4. I also logged into the VRM portal of the Victron website and found the Cerbo GX device there and it was sending data to Victron


However, what I do not know is what domain name/IP address belonging to Vcitron energy the Cerbo GX device was sending it to? Is there a way for me to get this information?

Thanks in advance

I'm not sure if I can be of big help here, but see if Q15 in the FAQ of the Cerbo GX manual brings you any further. It contains all public domain names and ports that the Cerbo connects to. Information other than that given there is not public.
