Hello ZS1SCI, Thanks for info, I'm running Deye sun-5k-sg03lp1-eu inverter. Looks like it's time to buy ESP and my Neeeeeeey balancer is already on the way from China 🙂

Thanks for sharing the changelog. > 10. Modify the full charge request voltage to 3.65*16=58.4V; This is what I'm trying to escape, I don't want to get an overvoltage alarm and I believe 3.6 is more than enough for LiFePO4. The dilemma: upgrade and face a potential issue with overvoltage or live with the current firmware and inability to read cell voltage data/connect to BMS with LVESS software. And there is no easy way to downgrade battery firmware, right?

I'm getting very few frames and only three of them change raw data over time Nothing starts with either 0B or 0C or 0D. I've tried another program that came with USB2CAN adapter and the result is the same: Could the reason be that my Deye BMS firmware is pretty "old" - 2004?

@ZS1SCI Thank you very much, now I finally got some data from my battery. What I'm really interested in is individual cell voltages which are not available via PCS as far as I can understand. I've changed the wiring to pins 1-2 and used InterCAN port at 250K with InterCAN_Bus.xml from this post. Got some data but not Cell information. Is it possible to somehow get Cell information? P.S. esphome-deye-bms sounds interesting, but I'm a newbie in all this stuff: ESP32, MCP2515, and HomeAssistance sound like "magic" keywords to me right now 🙂

@ZS1SCI Hello, I'm trying to get information from my Deye SE-G5.1 Pro battery but have had no luck so far. Perhaps you can help me. I bought USB2CAN adapter (China version described in https://github.com/tixiv/CAN-Monitor-qt) connected it to CANIN port and tried to use CANMonitor with XML files from your repo https://github.com/Psynosaur/Deye_Battery_Serial_BUS/tree/main/CAN2JSON/CANInformation I'm getting some data, but that data can't be decoded. I would appreciate it if you can help me.
