Weather Dashboard with ESP8266

Overview

A simple IoT-based weather dashboard using an ESP8266. The dashboard displays real-time weather data fetched from OpenWeatherAPI, along with local temperature readings received via MQTT. Time synchronization is handled via NTP, and all the data is displayed on an OLED screen.

Features

• Real-time weather information for a specific city
• Local temperature readings via MQTT
• NTP-based time synchronization
• OLED display for showing time and weather details

Hardware Requirements

• ESP8266-based microcontroller
• OLED display (128x64)
• Some MQTT broker for retrieving local readings

Software Requirements

• Arduino IDE with ESP8266 support
• Adafruit GFX Library
• Adafruit SSD1306 Library
• ArduinoJson Library
• PubSubClient Library
• NTPClient Library

Setup Instructions

1. Install Libraries: Make sure to install all the required libraries through the Arduino Library Manager.
2. WiFi and API Setup: Update the ssid, password, apiKey, and cityID in the Arduino sketch.
3. MQTT Broker: If you have a local MQTT broker, update the mqttServer, mqttPort, mqttUser, and mqttPassword in the Arduino sketch.
4. Compile and Upload: After making the necessary changes, compile and upload the sketch to your ESP8266.
5. Hardware Connections: Connect the OLED display to your ESP8266 according to your setup.
6. Run: Power up your ESP8266 and view real-time weather and time details on the OLED display.

Future Improvements

• Implement automatic city selection based on IP geolocation
• Add support for multiple MQTT topics
• Improve error handling for MQTT and API failures
