Flask ESP Simulator

Overview

This project simulates an ESP device using Flask and MQTT. It allows you to:

• Publish simulated motor responses and sensor data to MQTT topics
• Subscribe to MQTT topics via HTTP endpoints

Requirements

• Python 3.8+
• MQTT broker (e.g., Mosquitto, EMQX)
• See requirements.txt for Python dependencies

Setup

1. Install dependencies:

   pip install -r requirements.txt

2. Create a .env file in the project root with the following variables:

   MQTT_BROKER=your_mqtt_broker_url
   MQTT_PORT=8883
   ESP_TOKEN=your_esp_token
   APPLICATION_RUNNING_PORT=5005

Usage

Start the Flask server:

python app.py

Endpoints

• POST /publish-motor-response
  Publish a motor response to a topic.
  Body: { "motor_response": {...}, "topic": "your/topic" }

• POST /publish-realtime-sensor-data
  Publish simulated sensor data.
  Body: { "espId": "...", "userId": "...", "topic": "your/topic" }

• POST /subscribe
  Subscribe to MQTT topics.
  Body: { "topics": ["topic1", "topic2"] }

Notes

• Uses TLS for MQTT (insecure, for development only)
• Prints MQTT events to the console
