You do almost anything with your mobile phone, but when it comes to your garage door, you have to resort to another remote control. This garage door opener does not require the installation of an application and it works with any phone that has a web browser built-in. The system is based on the tux-graphics Ethernet board. The circuit diagram has external connections, relay and optional connection to switch to sense the state of the door. The relay contacts are then to be connected in parallel to the wall mounted push buttons inside your garage. They mounted the Ethernet board on a small piece of wood together with some screw-on terminations for the cables.
