[gelöst] Daten per Telnet abgreifen.
-
Hallo zusammen,
ich habe einen Wemos D1 mit EasyESP.
EasyESP stellt mit per Telnet Daten vom RX-Pin zur Verfügung.
Hat jemand eine Idee wie ich die Daten in den ioBroker bekomme?!
Ich habe zwar diesen Adapter von @Bluefox und @hobbyquaker gefunden:
https://github.com/ioBroker/ioBroker.telnet
Jedoch ist er 6 Jahre alt und ohne weitere Beschreibung. -
Problem gelöst, habe diesen Code gefunden von www.letscontrolit.com
Damit baut man einfach meine (ursprünglich) gewünschte Serial2MQTT Brücke auf.#include <ESP8266WiFi.h> #include <PubSubClient.h> const char* ssid = "SSID"; const char* password = "PWD"; const char* mqtt_server = "192.168.XXX.XXX"; const char* topic_rx = "uart/rx"; const char* topic_tx = "uart/tx"; const byte numChars = 100; char receivedChars[numChars]; // an array to store the received data boolean newData = false; WiFiClient espClient; PubSubClient client(espClient); void setup() { pinMode(BUILTIN_LED, OUTPUT); // Initialize the BUILTIN_LED pin as an output Serial.begin(9600); setup_wifi(); client.setServer(mqtt_server, 1885); client.setCallback(callback); } void setup_wifi() { delay(10); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); } } void callback(char* topic, byte* payload, unsigned int length) { for (int i = 0; i < length; i++) { Serial.print((char)payload[i]); } Serial.println(); } String macToStr(const uint8_t* mac) { String result; for (int i = 0; i < 6; ++i) { result += String(mac[i], 16); if (i < 5) result += ':'; } return result; } void reconnect() { String clientName; clientName += "esp8266-"; uint8_t mac[6]; WiFi.macAddress(mac); clientName += macToStr(mac); clientName += "-"; clientName += String(micros() & 0xff, 16); while (!client.connected()) { if (client.connect((char*) clientName.c_str())) { // random client id digitalWrite(BUILTIN_LED, LOW); // low = high, so this turns on the led client.subscribe(topic_rx); // callback: mqtt bus -> arduino } else { digitalWrite(BUILTIN_LED, HIGH); // high = low, so this turns off the led delay(5000); } } } void loop() { if (!client.connected()) { reconnect(); } client.loop(); recvWithEndMarker(); showNewData(); } void recvWithEndMarker() { static byte ndx = 0; char endMarker = '\n'; char rc; while (Serial.available() > 0 && newData == false) { rc = Serial.read(); if (rc != endMarker) { receivedChars[ndx] = rc; ndx++; if (ndx >= numChars) { ndx = numChars - 1; } } else { receivedChars[ndx] = '\0'; // terminate the string ndx = 0; newData = true; } } } void showNewData() { if (newData == true) { client.publish(topic_tx, receivedChars); // publish: arduino -> mqtt bus newData = false; } }
