Hungarian Sanxing SX631 Read issue

[deesnow]

I tried to use this ESPHome P1 reader on Wemos D1 mini, unfortunately it does not parse the serial communication.

This is what I got on Serial port (originally I was able to capture it with Tasmota)

Because of the long string in 0-0:98.1.0 OBIS code on Tasmota I had to apply seriall buffer to 1700. I have tried to add this to configuration but did not recevice correct information.

uart:
  id: uart_bus
  rx_pin: RX
  rx_buffer_size: 1700

I saw the following in the logs:
