Can I change the GPIO tx and rx pins in the configuration file with another GPIO pin?

joshbenner commented 10 months ago

Yes. GPIO pin configuration is handled entirely by the ESPHome UART component.

thank you very much ,.i am new to H.A. I changed the tx and rx pins, is it correct? uart:

id: s21_uart tx_pin: GPIO18 rx_pin: GPIO19 baud_rate: 2400 data_bits: 8 parity: EVEN stop_bits: 2

I don't know the details of your setup, but it looks reasonable. You might be able to get better help for configuring UART in the ESPHome Discord.
