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. I went down a bit of a hardware rabbit hole and wrote a little writeup of my journey and a how-to. It's my first piece of public technical writing so I'm open to any feedback!
In plain words
This project enables users to integrate basic garage door and car HomeLink buttons with Home Assistant without expensive commercial solutions. The creator documented their process for connecting these existing buttons to trigger automations through Home Assistant, detailing the hardware modifications required. The guide shares a DIY approach to home automation that repurposes existing car and garage infrastructure instead of requiring new purchases.

Hey HN! Nick here – developer of Itsyhome, a menu bar app for macOS that gives you control over your whole HomeKit fleet (and very soon Home Assistant). I run 130+ HomeKit devices at home and the Home app was too heavy for quick adjustments. Full HomeKit support, favourites, hidden items, device groups, pinning of rooms/accessories/groups as separate menu bar items, iCloud sync – all in a native experience and tiny package.

I made a Raspberry with Qwen my local car AI12d ago · github.com · ▲146Found that you can actually run a 35B Qwen model on a Pi with very impressive intelligence and stability. Built connectors for car ODB to read all about car internals, and manufacturer's cloud service for stuff like changing AC or opening/ locking doors. Gave it info such as the full car manual. And then hooked it up with my other agents in our discussion room! So now it can answer car questions such as "when should I add oil and what kind of oil?" and help you fully offline, and when online talk with the agent family that includes all the most powerful models so they know how the car…

I might be the only SRE on Earth with his own bowling center. It's a more in-depth gig than you'd think. My family and I bought an abandoned 8-lane bowling center in the rural mid-west. In our small town there weren't many recreation options for families. You've heard of a food desert? This is an R&R desert. It had been abandoned for a good reason. The roof leaks, the electrical system was constantly surging, and my 70-year-old bowling equipment (still) doesn't work perfectly. The system that keeps your score is particularly interesting to me. It's the thing you watch during your game, but…

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness. To avoid this loop, I ended up creating Bento, a single HTML file with everything you need in a slide tool including animations and shared editing. There's no install or cloud login, everything works offline. The default deck is around 560 KB and it doesn't need to fetch anything once you got it. Open it in a browser and then you can…

A few days ago I found myself trying out GLM 5.2 and was really positively impressed. The capabilities and security I was getting from this LLM are similar to those I've gotten from models like Claude or GPT, and this really surprised me. But then I thought, "I wonder how it would work on a normal computer like mine," and above all, "I wonder if it would work without going into OOM on a computer like mine." So I started working with the help of agents to test this possibility. I started converting the model to int4, understanding MTP usage, and if possible implementing DSA for long context.…
