I have setup mydooropener with the Arduino Ethernet rev3 and the dfrobot relay shield. I have a successful setup except my door won't open. I have a Craftsman door opener. I have my Arduino programmed and plugged into my network. I can access it from the iPhone app and hear the relay click when I hit the open button in the app but the door doesn't open. I can push the button on the relay board and get it to open but it messes up the display screen on my garage door remote panel. My panel has a door open/close button, a light button and a lock button. It has programming buttons on the side of it and a display panel showing the date and time along with the battery charge level as it has a battery in the unit if the power goes out. I have connected the wires from relay two to the only two screws on the back of the remote door panel. I'm wondering if my door panel isn't more than just a button to open and close the door and the the closing of the relay is actually shorting out the panel.
Any thoughts on this?
