Summary
A dual channel relay enclosure for a wi-fi garage door opener.
It works with just about any model / make of garage door opener.
Note: The photos of the item “in use” are of a draft version (print settings below applied) where the lid wasn’t perfect, but I decided it was ‘good enough’. I have updated the design you see here to fix the fit and finish issues.
I started out with this instructable, detailing a rather old hardware setup using a dual channel relay board.
I didn’t much care for the PHP / Apache on Raspbian stack. I know other folks who have used this setup and had issues with SD card corruption.
So I ended up creating my own app in go to do the HTTP bits and handle the GPIO interaction.
Then I took it a step further and baked up a minimal Yocto Linux image with a read-only rootfs, to guard against the SD card corruption issue.
If you want to customize the linux image, you can read the docs in my bitbake layer.
