🌦️ Z-Weather

Z-Weather is a lightweight project designed to collect weather data such as temperature 🌡️ and humidity 💧 using an ESP8266 module and a DHT22 sensor. The collected data is transmitted in real-time using the MQTT (Message Queuing Telemetry Transport) protocol, a lightweight and efficient protocol designed for machine-to-machine communication. This project leverages RabbitMQ as the MQTT broker, ensuring reliable and efficient message routing from the ESP8266 to the server, which processes and monitors the incoming data.

In addition to MQTT, Z-Weather includes features like a WiFi Manager for easy network configuration, mDNS (Multicast DNS) for local device access via z-weather.local, and a Web UI for device control and monitoring. Settings are stored in EEPROM to ensure persistent configurations even after device reboot. This combination of features makes Z-Weather a powerful and easy-to-use weather monitoring tool, capable of providing real-time and reliable weather data, making it an excellent solution for both personal and professional weather tracking needs.

🚀 How to Use

Installation

1. Connect the ESP8266 module to your computer.
2. Install the ESP8266 board package in the Arduino IDE:
   • Open File > Preferences and add http://arduino.esp8266.com/stable/package_esp8266com_index.json to the Additional Board Manager URLs.
   • Go to Tools > Board > Boards Manager, search for ESP8266, and click Install.
3. Select the Generic ESP8266 Module board from the Tools > Board menu.
4. Install the required libraries listed in the Libraries and Dependencies section.
5. Open the project code in Arduino IDE and upload it to the ESP8266 module.
6. Once uploaded, the device is ready to use.

Initial Setup

1. Power on the ESP8266 device running the Z-Weather firmware.
2. The device will create a default WiFi network:
   • SSID: Z-Weather
   • Password: zweather

Configure WiFi

1. Connect your device to the default Z-Weather WiFi network.
2. Open a browser and navigate to 192.168.4.1 to access the configuration page.
3. Select the desired WiFi network, enter the password if required, and save the settings.
4. Upon successful connection, the default WiFi network will disappear, and the device will connect to the configured network.

Access the Web UI

1. Ensure your device is on the same WiFi network as the ESP8266.
2. Access the device using the domain: z-weather.local.

Configure MQTT

1. Open the Web UI by navigating to z-weather.local/config.
2. Enter the MQTT server details, including server address, username, and password (if applicable).
3. Save the configuration to start sending weather data to the MQTT server.

Monitor and Reset

• Use the Web UI to monitor device status and sensor data by navigating to z-weather.local/monitoring.
• Use the /reset page to reset configurations if necessary at z-weather.local/reset.

---

📋 Important Notes

• The domain z-weather.local can only be accessed if your device supports mDNS and is connected to the same WiFi network as the ESP8266.
• Ensure that your MQTT server is operational and ready to receive data from Z-Weather.
