unhandled data and bad header

[FritsOV]

In adition to post: https://github.com/syssi/esphome-seplos-bms/issues/86 and https://github.com/syssi/esphome-seplos-bms/issues/67
I also use the Seplos BMS 48200-1101-10E-SP118-16S (or 1101-4800-10E-BOM-V16-57FTDJR) in a Daly Green mason attached to 3 Victron multiplus II.
I managed to setup a esp8266 lilo with a ttl as described here https://github.com/syssi/esphome-seplos-bms/discussions/55#discussioncomment-9228944

I am getting some errors like unhandled data, bad header and failed CRC check.

how to resolve these errors?

Some thoughts:

1. The unhandled messages/warnings are fine and can be ignored. These are frames of frame type 0x5A. I don't know what the frame is used for. This frame type isn't implemented and therefor reported as unhandled. Do you know any details? Could you ask your seller/manufacturer about some details of this protocol flavor?
2. I assume the CRC errors can be reduced if a hardware UART is used instead of software serial (GPIO4/GPIO5). If you want to use the hardware UART you have to use GPIO1/GPIO3 and disable the logger (baud_rate: 0) here.

In general your setup is working properly and you are missing just a frame every now and then.

I already did and got the offer for an online meeting. I'm not a programmer but if you want to i can set this meeting including you.
I never could get the code working using the hardware uart. Could give it another try.
