Show HN: Connecting my dumb garage and car's homelink buttons to Home Assistant Hi all, I've been on parental leave and while working on my garage door, I thought to myself... it would be great to open up this garage door from my phone without having to buy a bunch of expensive stuff. That snowballed into, I want the garage door buttons on my car's rear view mirror to trigger automations in home assistant.

It's my first piece of public technical writing so I'm open to any feedback! https://ift.tt/Nj1A8f2 July 23, 2026 at 10:28PM

The real growth hack? Start small. Think niche. Micro niches are not limitations—they’re leverage.  Why Micro Niches Matter A micro niche is a hyper-specific segment of a broader market.
