This project is a firmware for the ESP32-S3 microcontroller that implements. It implements AT basic structure for the Quectel EC200T IoT module. This also includes a relay controller, a PZEM004T sensor interface, and a subscription manager for MQTT messages.
- AT Command Handling: Implements a AT command parser and handler for the Quectel EC200T module.
- Relay Controller: Manages relay states based on received commands.
- PZEM004T Sensor Interface: Reads and processes data from the PZEM004T power sensor.
- MQTT Subscription Manager: Handles subscription messages and commands for MQTT communication.
- Dev Containers Support: Includes support for VS Code Dev Containers and GitHub Codespaces for a seamless development experience.
This firmware is not optimized for production use. It is provided as-is, and using it in critical or high-risk applications is at your own risk. Please ensure thorough testing before deployment in any environment.
