NodeMCU Relay Module REST API

REST API for a ESP8266 MCU with a 8 Relay Module. Only tested with Amica NodeMCU.

1. Add a conf.h file with your WiFi credentials:

#define SSID "YourWifiSsid"
#define PW "YourPassword"

2. Compile and flash.

The API documentation is available on Postman.

The relay module is active low, this explains why ON leads to a LOW GPIO signal.

Connect the relay module IN1 to IN8 to GPIO 5, 4, 0, 14, 12, 2, 10, and 13.
