I tapped into the buttons on the wall and ran a pair of wires to the relayboard and connected them to common and normally open.
I am using a raspberry pi3b gpio pins to control a relay board which simulates someone pressing the garage door opener on the wall.
When the relay is triggered it closes the circuit hooked up to the garage motor and opens the garage.
After only writing software for many years in web development creating something that interacts with the real world was a special kind of excitement for me when i saw it.
It was anyway very helpful to understand the concept around dedicated rpi to control a motor from a relay.
My config settings.
I had to buy a new garage door opener remote because my old remote s button had disintegrated and no longer worked.

When you access the webserver from your browser of choice you will have a big button that triggers the garage door via a relay.
The cabling i use now is still the same for the command part.
As soon as you turned on the relay button text will be changed close to turn off the relay.
Let me relish my small victory for a moment now that we ve cheated our way past the garage door opener next time we can work on data logging and.
This tutorial assumes you have the gpio binding installed and have already gotten that working for other items.
