Tired of unreliable services like ThingESP or CallMeBot crashing your projects? In this tutorial, I show you the professional way to build a 2-way WhatsApp controller for your ESP32 using your own Private Server.
We will build a custom bridge from scratch using Python (Flask), the Twilio API, and Mosquitto MQTT. This architecture is faster, more secure, and gives you 100% control over your data.
🛠️ What we will build:
1. A Python Flask server hosted on a VPS to handle WhatsApp messages.
2. An MQTT Broker (Mosquitto) to bridge the gap between the server and the hardware.
3. An ESP32 sketch that subscribes to commands and publishes replies instantly.
