This is a small project, i am looking a quick resolution, you have to just use the Arduino debouce lib to connect 4 pins ( push buttons ) to the other 4 pins ( relay ) on a esp8266 microcontroller. i will share a quick demo as well. The push button should work even while the microcontroller is not connected to the internet. Protocol used ( MQTT )
