Hello
I have connected the Chargery BMS to my Venus GX and created a serial driver at the Venux box. Additionally, I have embedded the data to the Venus GX remote interface. Since I do not know if i am loowed to link directly, you can find a little more information victron energy community page. Just search for "VENUS GX receive data from external RS232 interface".
I am looking forward to share my code. But this is not that easy as it seems and I need to make some things simpler. Anyway, if you have any questions I can try to help you. First important notice: The TX signal is inverted and I need to programme my USB FT232 USB adapter to be able to read any data.
Bye
Tobi
Has anyone connected to the com3 port on these and seen what it spits out on a computer? The connection would be fairly simple, an RS232 connection to USB adapter is all that is needed, connect black to gnd and red to RX (the chargery is doing the transmitting, the RS232 to usb adapter is the reciever). A terminal program like Putty (Windows) or SerialTools (Mac OS) could then be used to see the data, provided you set the correct comport on the program.
Reason I ask, is that I would like to hook a BMS8T to a 8 pack of cells as the bms, and send the SOC and other data to the Raspberry Pi running Victrons Venus OS. This in turn would then command the inverter to shut down (if the battery was getting low) or tell the charge controller to throttle back (during TOC balancing) or stop when the battery is full.
