KC868-HAv2 esphome issue

[procet]

Hi, i'va a problem with ha v2 and an esp32 with esphome firmware.
i'll attach the yaml file and the esphome log file. i think there is something wrong in the yaml file because with the ha control software the unit works well.
you can see the startup of the ha v2 and me trying to turno on and off the switches from home assistant.
every time the crc check is failing.
what am i doing wrong?
Thank you very much

[admin]

if the HAv2 board work well, please ignore CRC errors.

[procet]

The CRC errors makes esphome ignore the data being sent by the ha board.
I cannot tell esphome to ignore the errors.

[admin]

i also see the error, but don't worry, board can work well.

[procet]

Home assistant can't speak with the hav2 board because all the messages coming from the UART are ignored by the CRC error. If I turn on an input on the board I can't see it on home assistant.

[admin]

you can do as this video:
https://youtu.be/S679QX6Hc6I

[procet]

I've done exactly like this video. There is something wrong.

Do you know why CRC check is failing? can you tell me please?

here is what happen when i push and release the input 1 on the board. sometimes it works like this, some times it give me crc error

[admin]

which ESP32 kincony board you are connected with HAv2?

[procet]

No kincony board, this is a esp32 development board. Wroom 32.
