Instead of using Arduino boards which require extra wifi shield Sunny decided to use WEMOS d1 8266. Later realized even Node MCU 8266 is better than wemos as it is compact in size with inbuilt WiFi.
Automated and hard coded the node mcu with Blynk Code. By pressing the button in Blynk App we can control switching on and off of the light
Automated with Alexa and IFTTT. Just by voice control we can switch on and off the light, provided the WIFI is working.
Using all 4 pins of the relay to control 4 lights with Alexa individually. The circuit is such that even if nodemcu is not powered or wifi is not working, the lights still are switched on if the switches are in switch on mode.
Here trying to randomly switch on and off the lights with Alexa.
Using Google Assistant as well as Alexa to control light.
Adding switches to control lights manually.
If we remove the node mcu power, the bulbs should still work.
Once the power is removed from the nodemcu, both bulbs glow and can be controlled manually by the switches
