Matter over Thread devices disconnecting

I have 30 Nanoleaf Essentials Matter Downlights added to my Homey Pro. I am able to pair and connect them just fine, but some of them become unreachable. When trying to turn them on or of from the Homey App i get a “Matter error: 0x0580”. The ligths that are unreachable in Homey are still reachable over Thread the Nanoleaf App. The Nanoleaf App reports that the lights that are unreachable are actually connected over Thread. So it looks like they are connected to the Thread network, but the Homey App somehow does not know about them. If I restart Homey a different set of downlights are unreachable, but I am never able to reach all of them. Over som time (usually days) more and more downlights disconnect from the Homey App, and become unreachable. Please advice, how do I get to a situation where Homey are able to talk to all my downlights all the time?

Homey losing connection to Matter devices is fairly common, I think the only thing you can do is contact Athom so they are aware of this issue.

Thank you! That is too bad. I have contacted Athom support.

I have the same situation what is so frustrating…
They has the “best guide” topic where the offer these nanoleaf lights and they dont work property…

Have you already tried it via the Apple/Android-Thread? I haven’t had a single interruption since I switched everything to the Apple-Thread.

That will only work if you already have an existing Apple/Android Thread border router though.

YES, just a suggestion, if such a thing is available…

I have an apple homepod mini, what can work but first I updated every nanoleaf to 4.1.3. via the nanoleaf app.
If that is not working I will try to get these on apple thread border router, thanks!

Homey Support replied today that: “I will forward your report to Development so they can take a look at it and try to fix it as soon as possible. I can’t give you any guarantees on when your issue will be found and solved, but please know that it will be placed in the right hands and will be investigated. For now this is all I can do for you, which is why I’m closing your ticket.”

We can hope this gets resolved, but I am not very optimistic.

How does that work? Do you connect the lights in the Apple Home app, and the control them through Apple Home, or can Homey directly communicate with the devices over the Thread network for Apple?

The Matter protocol has a feature called multi-admin that allows you to generate a code for adding a device to another platform.

  1. Pair with Apple HomeKit First:

• AFAIK, homekit first pairing has no option to join other thread networks.

• After paring with the physical matter code, choose the option in homekit called “enter pairing mode”.

• Use the generated code that popups after a second (different from physical one it came with), to pair with homey.

Which option you choose to pair with using this multi-admin code after pairing with homekit first (“via iOS” or “via homey pro”) wont change which thread network is used. The device remains part of the HomeKit Thread network but is controllable from Homey in addition to homekit.

  1. Pair with Homey First:

• With this option, you can control the Thread network that your device joins by choosing either “pair via iOS” or “pair via homey pro”.

• After paring with the physical matter code, choose the option in homey called “share matter device”.

• Use the generated code that popups after a second (different from physical one it came with), to pair with homekit.

• Regardless of the selected network, multi-admin ensures both platforms can control the device.
• The pairing order doesn’t matter when it comes to multi-admin control. Either platform can control the device and remove the device from itself or other platforms.
• The type of Thread Border Router (Apple’s or Homey’s) is irrelevant for multi-admin functionality.

I pair my devices with HomeKit first, connecting them to Apple’s Thread Border Router network. I have several HomePods and Apple TVs already. I dont have much experience with just using homey pros network. But I always add them to Homey using the multi-admin feature for cross-platform control and automation. Homekit automation is hot garbage.

Also a note on Nanoleaf devices. For some reason they all come with an insane default setting. Which is “Power Loss Recovery” being turned off out of the box. This is psychotic, unhinged default behavior. Always switch this on, unless you want any little power loss to be a factory reset event.

Are you controlling the lights through Homey, or through Apple Homekit?

I am now currently trying a different solution without adding a new Thread Network or Thread Border Router. And it seems to work.

  1. The Nanoleaf Downlights are configured to connect to the Homey Pro Thread Network. But, as stated before, there are allways a couple of lights that are unreachable.
  2. I have Home Assistant running on a Raspberry Pi 4B. I share the device from Homey to Home Assistant, so I am able to control the lights in Home Assistant directly. They are still using the Homey Pro Thread Network. The strange thing is that I am able to control lights in Home Assistant that are unreachable in Homey. Even though they use Homeys Thread Network.
  3. I add the lights a second time in Homey as Home Assistant Devices. And in this case they work fine i Homey. Even though they become unreachable as devices when added in Homey, they are still reachable when going through Home Assistant.

This seems to work. Most of my lights are reachable when I add them as Matter Devices, but there are allways a couple that are unreachable. When added as Home Assistant Devices they allways work (or have allways worked up until now).

So frustrating. This has to be a bug in how Homey communicates with these devices. I hope Homey are able to fix this.

You should submit a support request about your findings, as Athom don’t use this forum for support or to keep track of issues: https://support.homey.app/hc/en-us/articles/360015784034-Submitting-a-support-request

Thanks! I already have an open ticket for this. I’ll send them a link to my comment regarding my workaround.

Is there a difference between homey as first connection and apple homekit ?
I’m experiencing connection issues with my Nuki 4 and Aqara u200.
The Nuki was Rock solid from march to December 24. After that the connection is very unstable.

Ticket already open since January 25, got the first answer 5 weeks later.
