Home Station

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 #include #include 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); } </details>

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
