Hello guys,
I try to make this simple project because I have another project ( an irrigation programmer with 4 x relays, 1 x dth 22 , 1 x drop sensor and 1 x moister sensor) connected with node red and I want to migrate to home assistant. This project works very good.
I try from a week to figure out why my new project is not work. I use a ESP8266 NodeMCU the home assistant is installed on a laptop with Ubuntu and I use a docker. The ESP is connected on WiFi, the mqtt broker show me the connection but when I press button on the home automation interface nothing happens. On ESP I connect on the pin D2 a led.
This is the cod from arduino:
#include <ESP8266WiFi.h>
#include <PubSubClient.h>
// Update these with values suitable for your network.
const char* ssid = "Archer";
const char* password = "@test@";
const char* mqtt_server = "192.168.100.149";
WiFiClient espClient;
PubSubClient client(espClient);
int SwitchedPin = D2;
String switch1;
String strTopic;
String strPayload;
void setup_wifi() {
Serial.begin(115200);
delay(100);
// We start by connecting to a WiFi network
Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}
void callback(char* topic, byte* payload, unsigned int length) {
payload[length] = '\0';
strTopic = String((char*)topic);
if(strTopic == "ha/switch1")
{
switch1 = String((char*)payload);
if(switch1 == "ON")
{
Serial.println("ON");
Serial.println(strTopic);
Serial.println(strPayload);
digitalWrite(SwitchedPin, HIGH);
client.publish("ha/switch1", "ON");
}
else
{
Serial.println("OFF");
digitalWrite(SwitchedPin, LOW);
}
}
}
void reconnect() {
// Loop until we're reconnected
while (!client.connected()) {
Serial.print("Attempting MQTT connection...");
// Attempt to connect
if (client.connect("arduinoClient")) {
Serial.println("connected");
// Once connected, publish an announcement...
client.subscribe("ha/#");
} else {
Serial.print("failed, rc=");
Serial.print(client.state());
Serial.println(" try again in 5 seconds");
// Wait 5 seconds before retrying
delay(5000);
}
}
}
void setup()
{
setup_wifi();
client.setServer(mqtt_server, 1883);
client.setCallback(callback);
pinMode(SwitchedPin, OUTPUT);
digitalWrite(SwitchedPin, LOW);
}
void loop()
{
if (!client.connected()) {
reconnect();
}
client.loop();
}
This is the output from serial:
