Node Red - Get Info from BMS V2 Over VE Bus

Hi all! I'm new to Victron and Node Red.

I have a setup with a Cerbo GX, 3 Multiplus II inverters, and a BMS V2 all connected via VE Bus. I want to use Node Red on the Cerbo GX to get info from the BMS and control a relay. I've verified that the devices are all communicating over VE Bus, but I can't seem to find a way to access the BMS V2 in Node Red. It doesn't show up as an option in either the "Battery Monitor" or "VE Bus System" Nodes. Any ideas?

By the way, the specific value that I want is the state of the "Charge Disconnect" output on the BMS.

Venus os beta 3.10~32 has 2 new custom nodes. These nodes give you easy access to dbus. If you are running an older version you can use mqtt to get values from dbus.
