External Components要怎么写？

coolguy

ESP home升级到最新版，Custom Components不能用了，需要改成External Components，问了几个AI，都写不对，只有来求助各位大佬了！
实现的功能就是读取UART RX 并设置到text sensor。
之前参考的帖子：
https://bbs.hassbian.com/thread-9794-1-1.html
https://bbs.hassbian.com/thread-23167-1-1.html

组件：

#include "esphome.h"
using namespace esphome;

class MyCustomComponent : public Component, public uart::UARTDevice {
 protected:
  unsigned char telegram[100];
  char data[100];

  bool read_message() {
    int i = 0;
    if (available()) {
      while (available()) {
        telegram[i] = read();
        data[i] = (char) telegram[i];
        ESP_LOGD("DmsrCustom", "0x%x", telegram[i]);
        i++;
      }
      data[i] = 0;
      ESP_LOGD("DmsrCustom", data);
      uart_text_sensors->publish_state(data);
    }
    return false;
  }
 public:
  MyCustomComponent(UARTComponent *parent) : UARTDevice(parent) {}
  TextSensor *uart_text_sensors = new TextSensor();

  void setup() override {
    // nothing to do here
  }
  void loop() override {
    // Use Arduino API to read data, for example
    if (available()) {
      ESP_LOGD("DmsrCustom", "loop start");
      read_message();
    }
  }
};
