Read until footer. //while (!footerfound && currentMillis - previousMillis < 5000) { // Loop while there's no footer found with a maximum of 5 seconds // currentMillis = millis(); // Loop while there's data to read while (available()) { // Loop while there's data if (telegramlen >= P1_MAXTELEGRAMLENGTH) { // Buffer overflow headerfound = false; footerfound = false; ESP_LOGD("DmsrCustom","Error: Message larger than buffer"); break; } //bytes_read++; //c = read(); telegram[telegramlen++] = read(); } // While data available telegram[telegramlen] = 0; //} // !footerfound if(telegramlen>1) s_energy_delivered_tariff1->publish_state(telegram); } return false; } public: CustomP1UartComponent(UARTComponent *parent) : UARTDevice(parent) {} TextSensor *s_energy_delivered_tariff1 = new TextSensor(); void setup() override { lastread = 0; } void loop() override { unsigned long now = millis(); // if (now - lastread > DELAY_MS || lastread == 0) { // lastread = now; if (data_available()) { // Check for x seconds if there's data available bool have_message = read_message(); } // } } }; 然后在esphome里面配置text sensor esphome: name: esphome32 platform: ESP32 board: nodemcu-32s includes: - uarttext_sensor.h text_sensor: - platform: custom lambda: |- auto dsmr_p1_sensor = new CustomP1UartComponent(id(uart_bus1)); App.register_component(dsmr_p1_sensor); return {dsmr_p1_sensor->s_energy_delivered_tariff1}; text_sensors: name: "My Custom Text Sensor" uart: - id: uart_bus1 tx_pin: GPIO15 rx_pin: GPIO35 baud_rate: 9600 当uart收到消息时会更新textsensor，然后在MQTT里面就可以看到更新了。 当然esphome的mqtt别忘了打开 mqtt: broker: 192.168.xx.xxx username: admin password: xxxx 帖子没说esphome怎么搞，如果不懂esphome的先去搜索别的帖子搞懂esphome。 游客，如果您要查看本帖隐藏内容请回复 |
