The wiring to the garage door opener will vary depending on what model your opener is. I have a Genie brand opener and the manual for it included a schematic diagram I was able to connect to an existing switch on the opener that has 8V when the door is fully or partially open and 0V when the door is fully closed. I would expect that all garage openers have some way of detecting when the door is fully closed. You should look through the manual for your opener to see if it contains a schematic diagram.
However the LG DOOR CLOSED connection to pin 5 of the Arduino is only used to determine whether the open door icon is shown or the closed door icon is shown. It does not affect the relay.
Here again, your garage opener may operate differently, but for mine, there is a switch on the wall that opens or closes the garage. That garage opener switch is normally open and closes when the button is pressed. I checked it with a volt meter and found that one wire always had 0 volts, and the other wire had 5 volts when the switch was not pressed, and 0 volts when the switch was pressed. So I tied into that wire that goes to 0 volts when pressed and attached that to the relay. So that when the relay closes it goes to 0 volts.
You said that the relay does not activate. Some things for you to check: Verify that the voltage on pin 2 of the Arduino changes. If not then there is a problem on the Arduino or Teleduino side. Go through the Teleduino tutorials at https://www.teleduino.org/documentation/tutorials. Specifically the first tutorial with installation instructions, and the one for controlling a relay. If the voltage on pin 2 does change, then the problem lies in the relay or the wiring. Again the wiring there may be different depending on which garage door model you have.
Good luck. I hope you get it working. It is very convenient to have.
Mike

Hi there, i'm trying to get your code working here. I know I have communication with the arduino via web because i can get the device to reset via a browser GUI. however, i cant get any of the relays to activate. also I don't quite understand the part of the schematic where "LG DOOR CLOSED" connects to pin 5. Where on the opener does that connect?
Thanks! Ben
