Wrong UART config for Lilygo T-Dongle S3

[7leman7]

First of all - thanks for the hard work on the component!

Since Lilygo T-Dongle S3 is the recommended stick it would probably make sense to mention directly in the README that it uses GPIO19 and GPIO20 pins as USB_D+ and USB_D-, so UART confirguartion should be adjusted for it to work:

_uart: tx_pin: 19 rx_pin: 20 baudrate: 9600

My working yaml config for Lilygo T-Dongle S3 (no display) is as follows:

substitutions:
  name: "water-heater"
  # main prefix for all entities
  friendly_name: Water Heater
  # name of your node
  node_name: "water-heater"
  # use "esp12e" for iot-uni-dongle, "esp8285" for coolrf-heatstick, or your own if you know it
  board: "esp32-s3-devkitc-1"
  # time platform: "sntp" or "homeassistant"
  time_platform: "sntp"
  # SSID of your wifi
  wifi_ssid: !secret wifi_ssid
  # password of your wifi
  wifi_password: !secret wifi_password
  # password for fallback wifi hotspot
  wifi_ap_password: !secret wifi_fallback_password
  # UART configuration.
  tx_pin: TX
  rx_pin: RX

Also, in the current version of the readme yaml configuration shown in the text seems outdated, an the correct one is only available via "download" link...
