Components for the Solar-Powered Smart Display

1. Broken Screen Laptop: Salvage your laptop with a non-functional or damaged screen, repurposing it for a new role as a smart display.

2. External 32-Inch Display: Connect an external 32-inch display to the laptop, serving as the primary visual interface for the smart display.

3. Solar Battery System: Implement a solar battery system to power the laptop independently, reducing reliance on traditional power sources and embracing eco-friendly practices.

4. Rainmeter Software: Utilize Rainmeter, a versatile desktop customization tool, to create a visually appealing and customizable display on the external monitor.

5. OpenWeather API: Integrate the OpenWeather API for real-time weather updates. This API fetches weather data, enhancing the display with up-to-date information.

6. Airflow, Kafka, and PostgreSQL: Employ Apache Airflow to orchestrate the data flow. Use Kafka as a distributed event streaming platform to transmit weather data, and PostgreSQL as a database to store the information efficiently.

7. Home Assistant: Integrate Home Assistant for smart home automation. Connect and control various smart devices to enhance the overall functionality of your smart display.

Setting Up the Solar-Powered Smart Display

Hardware Configuration

1. Connect the external 32-inch display to the laptop, utilizing available ports.
2. Establish a stable power connection between the laptop and the solar battery system.

Software Integration

1. Install Rainmeter on the laptop and configure it to display the desired widgets on the external monitor.
2. Set up Apache Airflow, Kafka, PostgreSQL, and Home Assistant on the laptop.

API Interaction

1. Obtain an API key from OpenWeather and configure the laptop to fetch weather information using this key.
2. Create an Airflow DAG (Directed Acyclic Graph) to periodically fetch weather data from OpenWeather and publish it to the Kafka topic.

Data Storage

1. Configure another Airflow DAG to consume data from the Kafka topic and store it in PostgreSQL for persistent storage.

Smart Home Automation

1. Integrate Home Assistant with your smart display to control and monitor smart home devices seamlessly.

Display Automation

1. Develop a Rainmeter skin that dynamically updates based on the weather data stored in PostgreSQL and interacts with Home Assistant for smart home automation.
2. Configure Rainmeter to display real-time weather information, customizable widgets, and smart home device status on the 32-inch external screen.
