Description
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!

Could you build this?
No This is a custom hardware, RF engineering, and physical wiring DIY project involving soldering, relays, RF receivers, and physical garage mechanisms rather than standalone software.
What it would actually take: The project requires physical hardware integration: wiring low-voltage dry contact relays (e.g., Zooz Zen16 multi-relay) to physical garage opener terminals, installing magnetic reed switches for physical state detection, and interfacing RF receivers (Liftmaster 850LM) via Z-Wave to a Home Assistant gateway. The hard parts are electrical safety, RF signal sniffing/pairing with Security+ protocols, and hardware debugging. It requires physical tools, electronics experience, and home automation hardware setup.

Same idea, different domain
Nobody's really built a workflow automation tool for Real estate yet.
