Based on the model from Deses, I wanted to turn my garage doors into smart garage doors. I decided to use a 2-channel relay, connect it to two of the buttons on an existing garage door remote.

The relay mimics the buttons being pressed when activated, resulting in the garage doors to open.

Changes from Deses' model:

• Closed the side with the relay outputs, no need to access them
• Added a cavity for a B&D TB5 garage opener in the lid
