Am from a software background and i don't know much about the hardware stuff. I need to automate my home with the Raspberry pi 3 model B
I am planning to make my Raspberry pi as a local server and using a web application from phone to control all electric device of my home (ON/OFF)
I was planning for a staircase wiring that the device can control by both physical switches and also from my web interface
I have watched many tutorial for controlling electric device with Raspberry pi GPIO pins and Relay channel.But if go for this method i need to bring all the phase wire lead from all my 2 way switch to Raspberry pi or near by area to control each device by inputs from GPIO pins.I think its very hard to implement with these large ammount of wires
Is there any wifi module or board is available for Raspberry pi to connect with RPI over wifi and Trigger the channel relay based on the input from RPI.so i can done the wiring without bringing the phase lead from each device to RPI.
any link or update will helpful
Thanks in advance
