This is the basis for pretty much ANY ESP-based firmware project. It'll get your device online.

The parts
Work Environment (Platformio/VSC setup)
MQTT
This is intended to be added to the baseline.
You'll need to add:
lib_deps =
PubSubClient
to your platformio.ini file.
main.cpp
Add:
setup_mqtt();
to setup() after the setup_wifi(); call.
Put:
DOtheBloodyMQTT();
inside loop()
The rest of the parts
OTA
Gurus source code...
Ffffffuuuuuuuu......
Configuration HotSpot
Wiegand RFID keypad
NeoPixels
Extreme WIP
This is intended to be added to the baseline.
You'll need to add:
lib_deps =
Adafruit NeoPixel
to your platformio.ini file.
and put
#include <Adafruit_NeoPixel.h>
in your source
Web Serving
TFT Display
OLED Display
(upcoming)

- DS18B20
- BME280
- Si7021

Energy Monitoring
Multitasking
Jean-Francois Turcots SimpleTimer Library makes this fairly straightforward. It allows you to specify that any function run repeatedly (triggered independantly of whatever is going on in loop().
Add SimpleTimer to the lib_deps in yout platformio.ini file.
an Example
1 #include <SimpleTimer.h>
2
3 // the timer object
4 SimpleTimer timer;
5
6 // functions to be executed periodically
7 void repeatMe() {
8 Serial.print("Uptime (s): ");
9 Serial.println(millis() / 1000);
10 }
11
12 void repeatMe2() {
13 Serial.print("Boop: ");
14 Serial.println(millis() / 1000);
15 }
16
17 void setup() {
18 Serial.begin(9600);
19 timer.setInterval(1000, repeatMe); // Run RepeatMe() every 1000 miliseconds.
20 timer.setInterval(100, repeatMe2); // Run RepeatMe2() every 100 miliseconds.
21 }
22
23 void loop() {
24 timer.run();
