Hi
I'mnew to HA and I want to connect my Mtter over wifi devices to my google home but I can't figure it out. With HomeKit it was pretty straightforward and I was able to add a bridge and scan the code in Apple Home app and see all of the devices.
Thanks 🙂

Does that involve Home Assistant?
silent wren
I've connected all of the matter devices to Home Assistant.
I just want to be able to control the devices from Google Home and HomeKit.
for Home Assistant I have an app that I can control it (not that I need to..)
@subtle rain sorry for late response

HA entities can be exposed to HomeKit and with an HA Cloud subscription, exposing to Google is easy as well. Without exposing to Google is possible, but harder.

How can it be acheived without the HA Cloud?...
subtle rain
By setting up an own Google Home skill in the Google developer tools.

See https://github.com/home-assistant/home-assistant.io/issues/35867#issuecomment-2494797373 for up-to-date instructions for Google Home
Official docs were finally updated in the last few days

@silent wren you can use Home Assistant Matter Hub, I think that is what you actually want. I first was confused with the Matter Integration in HA myself and I thought I can just connect HA over Matter with other Smart Home Systems, thats not the case. Though since fall lass year there exist this addon which does exactly that. Tough the matter standard is a mess and some stuff will not work like a proper Auto Mode for climate.

Also the non HA way of connecting Google Home is a pain if you dont have a real ipv4 address. Dont even bother.
So I recommend this addon it does 99% of the stuff you want
This stays local and fast without jumping through the internet
silent wren
Thanks for the help!
should I use only the official docs or a combination of the two?
grizzled smelt
Well, that's up to you which route you want - there's advantages and disadvantages to either
The official integration is "well known", but can also be a pain to get working because of Google
The matter hub route should be easier, if everything aligns
noble edge
yes it provides a qr code
for the Matter Hub you NEED a Matter Enabled Device every Google Speaker from the Home Mini upwards support it I dont think the original Google Home does.
The only real downside I found is that it doesnt support cameras (yet) and the auto mode in climates.
Though the camera thing is more of a google home thing then a issue of this addon, because google still doesnt support matter cameras
silent wren
Ohhh.. I thought that I would only need this addon. I guess I should buy a speaker as well 🙂
How about to connect other things from HA to Google Home?
Like boiler, TV, Cast and other devices that aren't Matter but they are to me 😂 , seriously, How? with the Homekit bridge I can see them all very well
grizzled smelt
This project simulates bridges to publish your entities from Home Assistant to any Matter-compatible controller like Alexa,
That's the whole point of the matter hub that @noble edge linked 😉
silent wren
Just to clarify, I DO NEED Google Nest? right?
grizzled smelt
For that app to work, yes, that's what their docs say
