ESP Sensors Project Improvement Tasks

This document contains a comprehensive list of improvement tasks for the ESP Sensors project. Each task is marked with a checkbox [ ] that can be checked off when completed.

Architecture Improvements

1. Refactor the sensor class hierarchy

   • Standardize method implementations across sensor types (e.g., ensure all sensors override read())
   • Consider using composition instead of multiple inheritance in DHT22Sensor
   • Create a clear interface for all sensor types to implement

2. Modularize the configuration system

   • Split config.py into smaller modules (e.g., config_core.py, config_sensors.py, config_mqtt.py)
   • Create a generic configuration retrieval function to reduce code duplication
   • Implement a configuration validation system

3. Improve MQTT implementation

   • Complete the MQTT configuration update feature
   • Consider using an existing MQTT library instead of custom implementation
   • Add support for MQTT QoS levels and retained messages
   • Implement proper MQTT message handling with callbacks
   • Fix socket timeout error in ESP32MQTTClient when reading from config topic

4. Enhance error handling and logging

   • Implement a centralized logging system
   • Add more detailed error messages and error codes
   • Create a mechanism to store error logs for later retrieval

5. Implement a proper plugin system

   • Allow dynamic loading of sensor types
   • Create a standardized way to register new sensor types
   • Support third-party sensor implementations

Code-Level Improvements

6. Fix inconsistencies in sensor implementations

   • Ensure HumiditySensor overrides the read() method
   • Standardize method naming conventions across sensor types
   • Ensure consistent error handling in all sensor read methods

7. Improve type hints and documentation

   • Add complete type hints to all functions and methods
   • Ensure all classes and methods have proper docstrings
   • Add usage examples to docstrings

8. Enhance test coverage

   • Add unit tests for all sensor types
   • Create integration tests for MQTT functionality
   • Implement simulation-based tests for hardware components

9. Optimize memory usage

   • Review and optimize memory-intensive operations
   • Implement memory profiling in simulation mode
   • Add memory usage statistics to logs

10. Implement button-triggered display functionality

    • Complete the TODO in main.py for button-triggered display
    • Add debouncing for button presses
    • Support different display modes triggered by button presses

Feature Enhancements

11. Add support for more sensor types

    • Implement support for analog sensors
    • Add support for I2C and SPI sensors
    • Create a generic sensor interface for easy extension

12. Enhance MQTT capabilities

    • Add support for MQTT discovery (e.g., for Home Assistant integration)
    • Implement MQTT-based device control
    • Add support for MQTT over WebSockets

13. Improve power management

    • Optimize deep sleep configuration
    • Add battery level monitoring and reporting
    • Implement adaptive sleep intervals based on battery level

14. Enhance display functionality

    • Add support for different display types (e.g., LCD, e-paper)
    • Implement customizable display layouts
    • Add graphical elements (charts, icons) to display

15. Implement over-the-air (OTA) updates

    • Add support for firmware updates via MQTT
    • Implement a secure update mechanism
    • Add version checking and rollback capability

Documentation and Usability

16. Improve project documentation

    • Document all configuration options

17. Enhance developer experience

    • Create a development environment setup guide
    • Add more detailed comments in complex code sections
    • Implement a consistent code style across the project

18. Improve deployment process

    • Streamline the firmware flashing process
    • Create a web-based configuration interface
    • Add support for configuration profiles

19. Add monitoring and diagnostics

    • Implement a health check system
    • Add performance metrics collection
    • Create a diagnostic mode for troubleshooting

20. Enhance security
