    Both can be done. The two wires going to the wall switch, they both come from the door opener, you can connect to these wires at the opener itself or at the switch.It is better to use the switch though.Thanks,

    Glad it works now! It is useful.Thanks for letting me know!

    Hi,When the relay is ON, the normally open terminals close, as they close this kills the power to the switch and that is how it works. Can you hear a click sound as the relay goes ON and OFF? if not, then your relay is always ON and you need to review your circuit!The relay should only go ON when there is light on the photo sensor.The sensor must be covered and not exposed to external light.If you have any questions, Please do not hesitate asking, would be very useful if you add photos.Thank you,

  • Open Your Garage Door From Anywhere Plus Security Cam!

    Hi,Why do you want to climb over your car?? Your phone should be close to the wall mounted switch and it has nothing to do with door opener mechanism.You provide power to the device from the same charger you use to charge your phone, it works on 5 volts.As in the other reply, connect the relay terminals to the switch terminals. Please measure the voltage first, because I do not know what kind of garage opener you use. Normally, the voltage at the switch between 14 to 17 volts and you shorten this voltage as you click the switch to open the door.Thank you,

    Hi,Just run two wires from the relay terminals, the common and the normally open ones, connect them to the two points your wall mounted switch closes when clicked.Thank you,
