ESP32 Doorbell using WiFi+MQTT

ESP32 Doorbell using WiFi+MQTT

This project was written with the goal of letting a user to use an ESP32 MCU board to send MQTT messages over WiFi when the button is pressed, which can be chained with automation tools to do neat & cool stuff, only limited by the imagination!

How to build - Linux host guide

First, install the ESP32 toolchain on your host machine:

• Standard Toolchain Setup for Linux and macOS

Follow the guide from step 2 to step 5, so you basically have the full toolchain. You should be able to invoke get_idf from your shell to continue with building.

Wi-Fi & MQTT details

Run the bootstrap.sh script to generate the appropriate mqtt_options.h and wifi_creds.h files. Then, change the details to match your application environment.

Compile, flash and debug

You might need to adjust the unix permissions on the exposed device node that is used for flashing the ESP32 device. Then, run the following commands:

get_idf
idf.py build
idf.py -p YOUR_PORT flash # Don't forget to set YOUR_PORT to wherever Linux created the device node

If you want to debug the application, run:

idf.py monitor
