Low Cost 4 channel Wifi switch

Hello everyone, I am going to share my project of wifi switch. My requirements: It should incur low cost as far as hardware is concerned. The device should be reliable as I would be using it to control lights at my home while I am on a vacation. I should get an update on my mobile once the switch changes state. Opted Solution: For the hardware I chose ESP 8266-01 as the wifi and control module from Aliexpress with few other discreet low cost components. A four channel relay board from NSK…

hope it helps.
