A quick note before we give out the wiring schematics. Please do not try installing this device if you are unsure of how electrical circuits operate
within your home. As exciting as it is to have a smart switch installed, it can be dangerous and even life-threatening if you do not install this
correctly. Please consult a qualified electrician if necessary. With that said, here are a few other warnings we’d like to point out for your safety:
