Home Station

Server and dashboard for my home station. Minor Smart Things 2023

Using the hub

DISCLAIMER: the weather station hub is currently still under development don't expect any data to be kept!!!

Setting up your account

• Go to the server website: https://whub.duckdns.org

• Create a new account by pressing Sign Up button.

• Once you created your account, proceed by pressing the Login button and log in with your credentials

• Once your logged in create your own weatherstation by pressing Create Weatherstation

• Specify your weather station's location either by using the map or entering the coordinates yourself (optional) add url to your own dashboard

Connecting your weatherstation to the server

• Add following code to use mqtt

  MQTT code

  #include <Arduino.h>
  #include <WiFi.h>
  #include <PubSubClient.h>
  
  
  const char* ssid = "Tesla IoT";
  const char* password = "fsL6HgjN";
  
  const char* mqtt_server = "145.24.222.116";
  const char* mqtt_user = "minor";
  const char* mqtt_pass = "smartthings2023";
  const char* mqtt_topic = "weather";
  
  WiFiClient wifi_client;
  PubSubClient client(wifi_client);
  
  void reconnect();
  
  bool mqttConnect(){
    client.setServer(mqtt_server, 8884);
    Serial.print("Connecting to MQTT broker");
    while(!client.connected()){
      if(client.connect("esp32", mqtt_user, mqtt_pass)){
        Serial.println("CONNECTED TO MQTT");
      }
      Serial.print(".");
    }
    Serial.println();
    return true;
  }
  
  void initWiFi(){
    WiFi.mode(WIFI_STA);
    WiFi.begin(ssid, password);
    Serial.print("Connecting to WiFi...");
    while(WiFi.status() != WL_CONNECTED){
      Serial.print(".");
      delay(500);
    }
    Serial.println(WiFi.localIP());
    mqttConnect();
  }
  
  
  void setup() {
    // put your setup code here, to run once:
    Serial.begin(115200);
    initWiFi();
    delay(500);
  }
  
  void loop() {
    // put your main code here, to run repeatedly:
    float temp = 24.0;
    float humid = 23;
    if(WiFi.status() == WL_CONNECTED){
      if(client.connected()){
        String data = "{\"user\":\"auke\", \"weather_station\": 2, \"data\": {\"temperature\":\""+ (String)temp+"\",\"humidity\":\""+ (String)humid+"\",\"wind_speed\":4.0 ,\"light_intensity\":40}}";
        if(!isnan(temp) && !isnan(humid)){
          Serial.print("Sent: ");
          Serial.println(data);
          const char* d = data.c_str();
          client.publish(mqtt_topic, d);
        }
      }else{
        mqttConnect();
      }
    }else{
      initWiFi();
    }
    client.loop();
    delay(1000);
  }
  

• Or use following code to use http

  HTTP code

  // setup POST request String url = "https://whub.duckdns.org/api/weather/"; char json[] = "{\"user\": \"YOUR_USERNAME\", \"weather_station\": YOUR_WEATHERSTATION_ID, \"data\": {\"humidity\": YOUR_HUMIDITY, \"temperature\": YOUR_TEMPERATURE, \"wind_speed\": YOUR_WINDSPEED}}"; HTTPClient http;

    http.begin(url);
    http.setAuthorization("YOUR_USERNAME", "YOUR_PASSWORD");
    http.addHeader("Content-Type", "application/json");
  
    // send POST request
    int httpResponseCode = http.POST(json);
  
    // check if POST request succeeded
    if (httpResponseCode > 0){
      String response = http.getString();
      Serial.println(httpResponseCode);
      Serial.println(response);
    } else {
      Serial.print("Error on sending POST: ");
      Serial.println(httpResponseCode);
    }
  
    // end connection
    http.end();
  

• Setup using the following settings:

  Host: 145.24.222.116
  Port: 8884
  Username: minor
  Password: smartthings2023
  

Sending data to the server

The server accepts data in JSON format, take a look at the examples:

{"user": "auke", "weather_station": 1, "data": {"humidity": 66.0, "temperature": 50, "wind_speed": 14, "gas": 20, "testval": 33, "speed": 44}}

{"user": "auke", "weather_station": 1, "data": {"humidity": 66.0, "temperature": 50}}

Make sure to use your own username and to specify your own weather station.

To get the ID of your weather station use the following link: https://whub.duckdns.org/api/stations and look for your username.

Final toughts

A dashboard is available at [http://whub.duckdns.org/dashboard] and is currently still under construction

You're welcome to create a pull request or create issues whenever you run into something or think some functionality could be improved.

TODO

• Set server to use HTTPS
• Encrypt MQTT traffic
• Move to domain?
• Inform user when not logged in on map
• Create seperate dashboards for each user
• Option to filter data in graph
• Phone friendly
• PWA
• Translation
• Dark mode

Developer setup

docker compose up -d
