homebridge-gsh VS matter.js

You don’t need to use HomeKit for this to work, but you will need https://github.com/oznu/homebridge-gsh. (Caveat: I haven’t tried this myself since I use HomeKit and Alexa devices.)

I have no idea about the Google Home Mini, but I managed to add my Nest Mini to HomeKit using the Enomek. You can try it as it simplifies the whole homebridge process. Also, Look for the homebridge-gsh plugin on github.

Since you’re a homebridge user, check out https://github.com/oznu/homebridge-gsh then you can set up google home on her pixel. Most smart home stuff already works with google home

I currently use homebridge-gsh as a way to have my Google Home speakers control my devices strictly through Homebridge. Is there a similar plugin that I could use the same way with HA where commands from Google Home interact with HA vs with each device's own cloud provider?

Maybe homebridge with this plugin? https://github.com/oznu/homebridge-gsh

Try this to add all the homekit devices in google home.

Sorry I thought I answered you, but I guess it never went through... but instead of the Alexa plugin, for Google Home you can use this plugin that does the same thing. I have tested this as well.

Answering myself once again.. I found the gsh (Google Smart Home) plugin for homebridge. Unfortunately, it requires running HB without authentication: https://github.com/oznu/homebridge-gsh

If you can do Typescript, matter.js makes it trivial to at least create a virtual matter device. Five minutes to clone the repo, build, run and pair with Google, Apple, Alexa, SmartThings, etc. The one caveat is certification. With Google you need to register as a developer so it allows an uncertified device. The others just give a warning.
