RS-485 Protocol #1

Open RossWilliamson opened 3 years ago

RossWilliamson commented 3 years ago

Just wondering if you had any idea how the RS-485 protocol would work. I think the GROWATT inverters don't all have CAN but instead use RS-485. I've read that they communicate with the pylon-tech batteries so I'm wondering what needs to be sent in order for the BMS to work.

Note I have batrium that outputs CAN pylontech protocal but no RS-485...

pylonthec RS485 protocol specification is widely available, just use google. or serach on github.

I did the search but could not find exact information. My goal is to connect Daly BMS to PI via uart and read SOC (this is done and working perfect), second goal is to connect Inverter Growatt to the same PI device and give him that SOC.

search pylontech in github, you will find many project with the pytontech specs available.
