To use Matter in Google Home, what do I need

As others had this before:

WiFi and Internet work well.

All of my Lightbulbs connect to the manufacturer's app with no problem.

They pair with Google Home via Matter with no problems.

However, they are listed in Google Home as offline, always, and cannot be controlled

…unless I have a Nest speaker connected. No matter in which room, or what's the distance.

I did check that my router has IPv6 enabled, and all firmware and software are up to date.

It actually used to work fine in the past, but then stopped

I can find no documentation for that.

Why? Is there any requirement that my router does not possess?

Thanks in advance!

I thought this was a simple question for this forum. Isn't it? 😕

Ok... is there a better place to ask?

Thanks in advance for any help 🙂

Hi @THF,

Thanks for reaching out to the community. I understand how confusing it can be when your Matter lightbulbs pair successfully but still show up as "Offline" in the Google Home app. I know this must be concerning, especially since they used to work fine before. I appreciate the detailed information you've shared so far and your efforts in troubleshooting. No worries, let's work together to get this resolved.

The core of the issue you’re seeing lies with the need for a dedicated Matter controller (sometimes called a "hub") to maintain the connection.

• Your Matter devices successfully pair and appear in the Google Home app. However, without an active Matter controller present on your local network, the Google Home app cannot consistently send commands or receive status updates, which leads to the devices displaying as Offline.
• When you connect your Nest speaker, it steps in to fulfill that controller role. This immediately brings your lights back online and makes them controllable, confirming that the missing component was the active hub function.

What You Need for Reliable Matter Connection: To use Matter devices reliably with Google Home, you need a compatible Google Nest Speaker or Display (like a Nest Audio, Nest Hub, etc.) actively connected to the same local network as your Matter devices to function as the Matter controller. This controller "mediates" communication for ongoing control, even if the initial pairing succeeds.

I hope this helps clarify the requirement. Let me know if you have any other questions.

Regards,
Jonathan

Thank you for your kind detailed reply, yes, I do have more questions trying to understand this.

1. Was it always like that for Matter over WiFi devices? - A special controller needed. I don't recall ever reading, seeing or needing this, and support for the lamps also knew nothing about this and sent me to replace them.
2. You say that I need a "compatible Google Nest Speaker or Display", but Matter was created to be a global standard. That's what it's for, right? So, can't I use another manufacturer or a router/access-point that can do that? And what about the other smart home apps, like from Samsung, Apple, Amazon? Do they need this too now? Only made by them?
3. Is there no good guide for that?

And yes, I do prefer Google devices, but sometimes there's a different need 😊

Hi @THF,

Thank you for following up and for sharing your additional questions. I understand that this information may be a little bit confusing, as you were not aware of this. I'd be more than glad to answer all your questions:

• In short, the answer is yes. For most major smart home platforms, you have always needed a device that acts as a Matter Controller (often referred to as a hub) to set up and control Matter devices, even those using Wi-Fi.
• Matter devices are universal, but the controller is how you manage them within a specific ecosystem (like Google Home, Alexa, or Apple Home). To control a device using the Google Home app or Google Assistant, you must have a compatible Google device (like a Nest Hub or Nest Mini) acting as the Matter Controller for that Google ecosystem. Some routers, such as the Nest Wifi Pro, have the required Matter Controller software built in and can fulfill the hub role. Not all routers do this yet.
• Every major smart home platform has the same requirement. To manage a device using the Apple Home app, you need an Apple HomePod or Apple TV. To use the Alexa app, you need a compatible Echo device. For example, you can set up the light with your Google Nest Hub and then "share" it with an Amazon Echo and a Samsung SmartThings Hub. All three platforms can then control that one device using their respective apps and voice assistants.
