To be honest, we thought the Cozy Vent would just work with Home Assistant. And it didn't. Our customers let us know it quick too.
So we bought a Home Assistant Green, dove into the logs, and started debugging line by line. After a few firmware updates and some serious trial-and-error, we got it working and are now happy to announce we officially have Home Assistant support!
This Home Assistant debugging journey reminded us of something important:
Matter is powerful, but it’s still a work in progress.
Different platforms interpret features a little differently. They have different in-built assumptions. But that’s the magic of Matter—and the reason we believe in it. It allows a small company like Cozy Home Labs to bring a useful, easy-to-use product like the Cozy Vent to life on the same playing field as the big guys.
