What is current status of Matter devices?

[someguy]

Is the Matter integration up and running?  Can in buy a matter device and expect it to connect to my PolISY?

[oberkc]

My experience is that one can use matter over wifi, but matter over thread is not ready yet.

[someguy]

I’m not completely sure what that means but I’d ask if I have a matter device that has a a WiFi connection then it should work?

As I understand, matter devices can communicate via two options: wifi, or a "thread" network.  The thread network was developed as part of the matter ecosystem, I believe, and requires a thread border router in order to complete the system.  If a particular matter device connects via wifi, then I expect you would be able to add this device to your ISY, though there may not be full functionality.  If a particular matter device communicates via the thread network, then I expect that you will have little success trying to add the device to your ISY.

And only able to include from Android  NOT IOS

SmartWings has a motor that is "Matter over Ethernet"...  would that not be a third?  Not arguing!  I just want to be knowledgeable.

Well that nanoleaf bulbs use thread, and I've tested them successfully.

Well Matter is over IPv6. Both ethernet and wifi are IP based so that isn't really a distinction, since the difference is at the physical and data link layers. The network layer is the same. Matter also implements IPv6 over Zigbee, which is what makes up the Thread communication option. This appears to be optimized for low power/battery device operation.

The implementation of Matter for the UDI controllers seems to have somewhat stalled, or slowed down. It's still in Alpha testing. It looks like a few other projects (like Homekit implementation) might have been given a bit more priority for the time being. The current release of IoX is still 5.9.1_18, and has been since April. It would be nice to have an update from UDI.

I have had different experience with nanoleaf bulbs, unfortunately.

Fair point.  I would assume that this is the same as wifi and would expect it to work.

Has anyone been able to add a Matter device to eISY that has already been added to Homekit or Alexa via a numeric 'setup code'?

Yes, if you're referring to a sharing code. Matter devices usually come with QR and/or PIN codes. Currently the only way to add a Matter device to your eisy is with a QR code. Unfortunately, some sharing applications will only give you a PIN code. So use one that offers a QR code. The Hue app does this, as does the Google Home app. I can't remember if the Alexa app does too. The share code is created in the app and expires, sometimes as quickly as after just a couple of minutes.

Another inconvenience is that the sharing QR code will often be displayed on your phone (almost everything today is managed with a phone app) and you also need to scan that QR code in UD Mobile...on your phone. So you either need two phones, or do what I did: use the phone's buttons to take a screen shot as a photo, email the picture to yourself, open the email on your PC screen, scan the QR code off the PC screen. All that before it expires!

Ok.  So it's not just me.  Yeah I would love it if the UD app would accept a sharing code.  As far as I can tell, amazon and Homekit don't generate sharing QR codes... just numeric codes.

Hi Everyone,

 

See the following for an update:

@Javi

Just confirming, commissioning still had the permissions issue with 1.2.9 but adding a wifi plug via setup code worked flawlessly on IOS

Great, thanks for the update.  I'm in the process of implementing BLE commissioning through iOS Matter APIs instead of handling BLE ourselves, maybe in the next release.

[Javi]

Bug discovered in version 1.2.9 - 1.2.10.  Causes failure on back navigation from folders on home tab and automations tab.  Fixed in 1.2.11

@Javi

confirming with latest UDM I added a device via commissioning with barcode and shared device to Homekit and Homekit to EISY.  Amazing great work  Thank you

For Matter over Thread a Thread Border router is required. The device can be added to the border router first, i.e. a Nest Hub Max, then share the device with eisy using the sharing QR Code or Pairing Code from the Border Router's app. Eisy will communicate with the Thread Border Router to control the device.  Note that Pairing Code entry still in UD Mobile beta for iOS.

I understand that a Thread Border router is required and I have tried all this.  I have a border router in the form of an echo hub and a google hub 2nd generation.  My trial device was a nano leaf bulb over thread.  I have an android phone, an iPad, and access to an iPhone, all with UDMobile and google home and the Alexa app.  I can add the leaf bulb to the echo hub and share it to the google hub and vice versa.  At the time, UD mobile required a QR code to add matter devices.  (Perhaps this has changed recently?).  I forget which hub and which version of the hub app allowed the sharing via QR code, but one did.  I tried adding it via UD mobile, and had no success.  I stopped trying.

I thought I kept up with the latest software versions for IOX and UDMobile.  Maybe there are newer versions out now.  I have been waiting for the bugs to surface and be corrected before spending any more time on this.
