Hi all!!
Im doing a project to read the information of my seplos BMS with a ESP32 and RS485 converter, and I have some problems and Im blocked for now (Im new with esphome).
I review all connection and the are ok, Im sure because i had connected the cable to the usb converter and works fine with the laptop and the battery monitor.
For now I received some information in the log, but honestly I not really sure if Im doing well and what I need for read and give format to the data.
this my script:

and I received in the log the next warning:

Please, if you can help me and give me some tricks to understand this world… is very complicated form me 
Thanks in advance and have a nice day.
