Apropos: I have a Victron solar charger that comes with a DSUB connector in the front where a display/controller attachment can be plugged in. The display almost certainly uses Victron's VE.Direct interface over TTL/serial and it exposes a reading (internal temperature of the charger) that is both extremely useful and not documented anywhere. I guess the cobbled-together way of solving this would be getting plugging in two USB-to-serial/TTL dongles and scripting them to, quite literally, MITM the communication between the charger body and the display, ferrying the packets over while logging them. But it occurred to me that maybe someone has made a device that makes this easier.
