123/Smart BMS to USB cable

The 123SmartBMS to USB cable is a handy cable which can be used to display BMS data on the Victron Cerbo/Venus or for custom 123SmartBMS projects like on the Raspberry Pi.

Victron GX integration

Installation is simple: just plug the cable into the 123\SmartBMS End Board Ext Out and the USB into the Victron GX. Download venus-data.tar.gz and put it on a usb drive or SD card (do not extract). Plug this USB drive/SD card into the Victron GX and reboot the GX. The software is now being installed. The installation of the software can take up to 5 minutes. You will see the 123\SmartBMS Manager appear. This Manager keeps track of all 123\SmartBMS connected.

After the installation, you can remove the USB drive/SD card.

For the whole installation process and explanation about the software, please see the Victron Integration support.

Important

1. This project requires VenusOS 2.80 or higher. Make sure you update to the latest release to get v2.80 or higher.

2. If you install it on VenusOS 2.80-2.89, you may need to reboot twice for installation.

3. The USB cable can only be plugged into the two USB ports on the edge. The third USB port is a power port and cannot be used.

Raspberry Pi projects

To speed up development of custom Raspberry Pi projects, we have developed code for the Raspberry Pi. This code connects to the BMS via the 123\SmartBMS to USB cable and can upload the BMS data to Thingspeak. For more installation instructions, please see our Github.
