We are renovating an existing installation and adding Lithium-Ion Batteries. Now we have an existing CCGX on the site with a Blue Solar MPPT 150/85 Charger using Can.Bus communication @ 250kbit/s. The Battery’s BMS is communicating Ve.Can @ 500 kbits/s. How can we get both comms working to get actual readings from both (non adjustable rates) units without changing the GX out with new version?
You should be able to add a second CANbus via a USB interface. I'm running a CANable one on my Raspberry PI. It's inexpensive and works well. The only drawback is it's a bare board (no enclosure).
Check here for more information:

I also have a script that makes adding additional ports easier:

It's only been tested on a Raspberry Pi but it should work on any system. It supports 2 CANbus interfaces (the most Venus OS supports).
Hi @Kevin Windrem, Thanks for sharing.
I have a problem, maybe you can help me.
I am receiving data from a BMS over CAN:
I suppose I should script this to appear in the Cerbo GX interface, do you have any material I can study on the subject?
