Hi, I have been working with the I2C relay for Industrial Switching automation project, in which I am working on a two-way switch principle in which one end is connected to the electric switch and another end is connected to relay switch controller via ESP8266 Controller. I am looking for the simple circuit which helps to sense the AC signal more than one electric switch and send the signal to ESP8266.

Any suggestion on this will be a great help.
