I just picked up a new Pi 4 Model B Rev 1.4 32GB. I would like to develop software (Python) to do some simple monitoring. My understanding is that I need to load the Venus OS, but it looks like that makes my Pi into a CCGX, which I already have.
What do I need on my Pi to access Victron devices on my network?
TIA…
The PI you just bought will NOT run Venus OS because of an incompatibility with the Rev 1.4 boards. For now, it's recommended to select a Pi 3 to run Venus OS on.
You could extract data from the CCGX using dBus calls over ssh, via MQTT or ModBus. You might also look into Signal K or Node Red, but you need to run the "large" version of Venus on the CCGX and it might be under powered.
This would likely be your starting point, but the Pi 4 is hit and miss and not supported as yet.
