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
