Custom Can-Bus profile

Hey Everyone,

I work with caravans in Australia and I’ve decoded the communication protocol for the BMPro electrical system. I’m looking at creating a canbus profile to suit this but I haven’t found much information in the process to do this.

Currently I connected the BMpro canbus to the cerbo VeCan port. I have full control using node red and can Even disconnect the master node and the cerbo can emulate the signals to allow the existing slave nodes to continue to work using the cerbo data.

I would like to be able to just load the profile, as currently I have to change the canbus baud rate after each update.

Since I’ve finished decoding the BMpro system, I’ve now moving onto the projecta system.

Any help would be awesome.

VE CAN ports are dedicated to Victron devices.
You should be using the BMS CAN profile/ports which run at the lower baud rate.
There are some existing projects on git that you could fork and attach your own profile to.
Have a look at the samsung battery topic in this section.

Thanks for the heads up nick, I just double checked sure enough its connected to the ve.bus ports, I’m running a cerbo-s so no BMS ports.

This BMPro system is running a 125k baud rate.

You can’t connect a battery to vebus ports. That is for the inverter only, using it with other devices will break the system.
The ve can port can be configured in settings to use a bms can profile.

Just don’t update if not needed?

My customers love there updates. Just trying to solve problems before they happen.

The system I’m connecting to isn’t a battery it’s a power management system,

Disable the automatic updates and if they do the update manually than let them pay for your time to fix it, that way they will quickly stop doing updates.

It’s the simplest solutions that are the greatest.

Cheers mate I’ll just do that.
