Matter issues and Homey losses connection

My frist question is dose anyone else have trouble with matter? I have to restart homey 3-4 times/week to reestablish matter connection. I get this error when it stops working and I try to switch the plugs on

“Could not reach (matter) network. Restart your (matter) router”

After restarting Homey pro it works again.

Second problem is that homey looses connection to the network. Flows still work (433mhz,z-wave,matter,wifi and Zigbee plugs still works) but can’t use the app. Same here after reboot it works fine again.

What could be the problem or is this a known issues?

Surely you’ve found the many posts on the forum about Homey losing network connection?

Don’t know why but my search gave me a year old post first so I thought it were fixed.but now I got more recent post…

But my search for the matter connection problem I get no hit.

They might be related.

I’m experiencing connectivity issues with some Matter devices.

A few devices are randomly inaccessible by Homey Pro. After rebooting Homey Pro, they usually reconnect. One of these devices is very close to the Home Pro, which is located in the same house as three HomePod mini speakers and two Apple TV devices.
I’ve verified that IPv6 is enabled and all devices are connected to the same network. I haven’t encountered any issues with Zigbee. I’ve restarted all devices to « clean up » the Thread/Matter network, but there hasn’t been any change. I’ve checked the device in the Dev tools, and it’s not reachable, even with a ping.

Are the devices using your Homey’s Thread network, or your Apple’s?

I suppose it’s an Apple network. Here’s how I go about adding a new Matter device:

1. I start with HomeKit.
2. Then, I add it to HA (which I found to be more reliable).
3. If the device comes from Aqara, I add it to Aqara Home.
4. Finally, I add it to Homey Pro (which gives me the most trouble with multiple attempts).

Of course, I don’t use the QR code on the device (except for the first one). However, when I add the device to the next platform I use, I use the « share » option, which generates a temporary QR code or Matter code.

I’ve never used the Homey’s Matter?

Well, you do, because you take the “share” QR code to pair it with Homey. That’s a Matter code (what you don’t use is Homey’s Thread).

But what I don’t understand is how HA comes into play. Do you do this:

  • Pair with HomeKit (using the device’s original QR code)
  • Add it to HA using a “share” QR code from HomeKit
  • Add it to Homey using a “share” QR code from HA?

I initially thought that doing that (as opposed to, for instance, sharing twice from HomeKit, once to HA and once to Homey) could add additional complexity to the whole setup, but thinking about it some more I don’t think it matters (no pun intended), and it might just be a case of Homey’s less-than-stellar networking (which has been an issue with Homey for many years, regardless of model).

Thanks, Robert. I did something I should have done a long time ago this morning: I reset (Factory setting) my Homey Pro. I’m rebuilding (without the backup) the entire house (I’m on holidays, :slight_smile: ).

I get a Homey mini initialized with a backup, so I have most of my setup.

So far, all Matter devices work better. Before I say “This fixes everything”, I’ll wait for a complete setup…

But after doing a lot of tests with this Homey, I guess it needs to be reset sometime.

We’ll see this week if it’s better.

Thanks

I’m running Matter-over-Thread with iOS integration and running into this issue too. The new developer view for matter shows the issue: Homey lost the ipv6 connection to this devices.

Sometime the device will be up again. Not sure, why this happen. I used an MDNS-browser (flare for iOS) to debug the annotation from this devices. Seems to work fine, it shows up with its services. But Homey won’t be able to connect :frowning:

The matter devices which are using Matter-over-Bridge, are working fine. Only the thread network seems to have issues.

So, I was tired of having these issues, So I decided to kill everything :wink: as I was in holidays.

I completely reinitialized my Homey Pro (2023), I decided to go back to the factory setting and I didn’t restore the backup !

1. I removed all Matter devices from Matter integration (HomeKit and HA) using the Matter function in iOS.

2. Then, I started adding my first Matter/Thread devices. I was almost able to add them to Homey using the iOS function, not the Homey one, it doesn’t work frequently. I’m looking at the dev tools quite often : Homey Developer Tools

3. During the holidays, I rebuilt most of my Flows. I created a screen of them, but with the experience I gained, I discovered many tricks that improved their performance.

4. I waited until the week before to add all my Matter devices to other platforms, using the “share’ function in Homey.

So far, everything is working smoothly. I haven’t received any more inaccessible Matter devices. I’ll observe how things progress over time, but I’m quite confident in the situation.

To be honest, I conducted numerous tests on my Homey Pro in 2024 and 2025, which could have potentially corrupted my configuration. That might explain that.

I wish you a happy New Year!

Do you think it’s a plausible story, or are you just relying on ChatGPT* to be accurate and trustworthy?

I found it here : Matter & Thread: A Guide Through the Jungle - Everything Matter - Aqara Forum

It doesn’t make sense at some points (it first says that the ULA prefix is fixed and independent of the internet provider, then says internet providers can change the GUA, which can cause local issues). What you didn’t write in your post though is that the original post says to activate (and fix) the ULA prefix in your router, which does make sense.
