How to set matter device endpoints default name? eg. I have Light Panel with 2 endpoints. endpoint 1 name: Open; endpoint 2 name: Close; I've tried FixedLabel, but it not work.

If I prefer for Google to not have access to my data, passwords, and passkeys when possible. Then what is exactly access when using devices via Matter? Does any data pass through even when not using Google services?

I tried to add my Eve Weather and Door & Window. It failed continuously and immediately with below log.

Hello. I'd like to ask below issue. I have two SmartThings hub and one Matter device. After I add it to the first hub, and then share this to the second hub with QR code, it always fails with below log.

Hello. I'd like to report something different behavior with before. In previous versions of iOS (16.1~), after completing Apple Home app → SmartThings iOS app Multi Fabric onboarding, there was only one iOS system fabric in the device's fabric list as shown below. Apple Home app Apple Keychain (iOS system fabric commissioned by the Apple Home app or SmartThings iOS app) SmartThings In iOS 16.6.1, after completing Apple Home app → ST iOS app Multi Fabric onboarding, the device's fabric list has been changed to include two iOS system fabrics as shown below. Apple Home app Apple Keychain (iOS system fabric commissioned by the Apple Home app) Apple Keychain (iOS system fabric commissioned by the SmartThings iOS app) SmartThings At this time, if the user removes the device from the SmartThings iOS app, only SmartThings fabric (4) will be deleted and Apple Keychain (3) will remain. Apple Home app Apple Keychain (iOS system fabric commissioned by the Apple Home app) Apple Keychain (iOS system fabric commissioned by the SmartThings iOS app) I'm afraid that it will fail if I try to add my device to Google Home or Alexa. Because max fabric count is 5 and it counts Apple keychain also. Is this behavior expected? Thanks.

I have run thru the Matter documentation and going to create my own non-standard cluster in my matter device for my own use case. Question is Can I control a non-standard matter cluster by HomeKit SDK? I run thru the HomeKit SDK document but cannot find any hints.

My app uses the HomeKit API and has been paired with a Matter device. How do I use the HomeKit API to open the matter device's ECM,and use mutiple fabric to share device with other ecosystem?

Hi, I'm professionally developing a Matter window covering, which needs support for an additional switch. Matter provides a way to customize devices by adding additional clusters to an existing endpoint. In my example, I would like to have a Window Covering Device on endpoints 1 & 2 (Cluster 0x0102) with each having an additional OnOff-Cluster (0x0006). The OnOff-Switch would change the device's behaviour internally. I also tried to use composed devices by having a Window Covering Device (on endpoints 1 & 3) combined with either a OnOff Plug-In Device and a OnOff Light (on endpoints 2 & 4) with a proper configuration of the PartsList-attributes. Both of these variations are working kind of. Drawbacks of the solutions: The Icons shown in Home are quit miss-leading. If the user chooses the "show as separate tiles"-option, the link between the slider and the switch get lost (I would hope, that the composed devices wouldn't separate). The names of the widgets get chosen randomly, so that "Shutter 1" is associated with "Light 2" and vice versa... I hoped, that if the Slider and the Switch would be on the same endpoint, I kind of magically works. But I isn't. The Switch is simply not shown (or did I miss id somewhere?). Is this under construction? Or is it already supported, but I did not implement it correctly? Please could you assist? BTW: My implementation is using the esp-matter SDK from Espressif. I tested my implementation with the CHIP-Tool and think I could verify the proper implementation. Thanks in advance.

There are a number of window covering types that have tilt only capabilities, such some venetian blinds. The matter specification allows for a window covering to have tilt only functionality and attributes. When I add one of the tilt only Matter accessories to the Home app, I get "This accessory is not responding" If I go into Accessory Details and Settings, I am still able to use the tilt slider (see photo), however the target tilt percentage is always sent as 100% (90 degrees) or 0% (0 degrees). There is no granularity.

Are the MatterSupport commissioning APIs supported in the iOS simulator? Specifically hoping to support Wi-Fi commissioning using an app running in the iOS simulator. Thank you!

Our smart home app is integrating Matter as a way to add devices to the user's home. The implementation is pretty standard, here is the main part: Code var setupPayload: MTRSetupPayload? if let onboardingPayload = onboardingPayload { setupPayload = try MTRSetupPayload(onboardingPayload: onboardingPayload) } let topology = MatterAddDeviceRequest.Topology( ecosystemName: ecosystemName, homes: [MatterAddDeviceRequest.Home(displayName: homeDisplayName)]) let request = MatterAddDeviceRequest(topology: topology, setupPayload: setupPayload) do { try await request.perform() print("Success") } catch { print("Failure") } Issue If the user decides to press the close button on the UI, the iOS treats it as a success. This use case messes with our flow as we have different paths in the app for success and failures. I would normally expect that if the user cancels something there is a callback that enables the developers to handle it properly. I've researched a lot on this topic but unfortunately I wasn't able to find anything helpful. Any advice on how to resolve this is much appreciated. Thanks in advance P.S. Yes we have implemented the MatterRequestExtension and all the handlers, the commissioning part works fine, we are able to add a Matter device and control it with our app, this issue happens before scanning the QR code.

Matter-enabled devices can be commissioned directly using MatterSupport and Default System UI. But what if we don't want that default system ui instead want to implement an entire customized flow as in Matter Sample iOS app. How can I do that if I'm using MatterSupport and want a custom flow instead of a default flow? Currently, in custom flow, the user has to enter ssid and password of the network connection, but I want to programmatically read SSID and password on the network and pass those as arguments to the chip controller for commissioning. Is it possible in iOS to read the credentials of a wifi network by any chance?

We are building a matter wifi thermostat. The device is working well with Google and Alexa. However, when add the device thru iOS Home App, the home app always show room temperature 0.0c. When working with Google Home, the room temperature can show correctly. Is there any problem with iOS Home App with Matter WiFi Thermostat?

Hello fellow developers, I am in the process of developing an iOS application that support the Matter Framework. My goal is to enable user to commission their Matter-enabled device to a fabric and control them through the fabric. However, I stumbled upon a few questions and areas that I would greatly appreciate guidance on: Commission Process What is the recommended steps to successfully commission a Matter-enabled device? Using the Matter API I have reviewed the provided sample app in the CHIP repo. However, I find it a bit complex to understand fully (background context: I am a junior developer and have never work on iOS development before). I replicated the app using Swift since the sample is written in ObjC but often times got stuck on [connection] nw_read_request_report [C1] Receive failed with error "Operation timed out" log. How to effectively use the Matter API to handle commissioning, device control and other interactions with Matter-enabled devices? Keypair generation I have noticed that the framework doesn't provide an API with the keypair generation (correct me if I am wrong). What is the best practice or resources for handling the keypair generation within the Matter context? Matter Support vs Matter framework I need clarification on the roles of these two framework. From my understanding, MatterSupport adds Matter devices into my ecosystem(?) while Matter framework handles the commission and control in the Matter fabric. And we can use the Matter framework within the MatterSupport using the request handler to commission Matter-enabled device.

Hi, we develop devices on Matter. I have two questions: I have a device with four buttons. These are programmable buttons that can be programmed for a short press and a long press. I have an issue that after pairing the buttons with Apple Home, all the buttons are displayed as button 1. They also appear in different environments each time. How do I need to configure the clusters for Apple Home to correctly recognize the buttons? How do I display the battery status? I'm using the Power Cluster, but Apple Home doesn't detect it. The battery doesn't show up in the app at all. On Samsung SmartThings, the battery works correctly. Best regards, HaWca.

Hello, I trying to commission and joint thread matter device through I-phone ( ios 16.3.1) and apple home pod mini (16.3.2). After scanning QR code and following setup process it fails to add accessory and iPhone shows" Pairing with device failed" (attaching screen shot). I confirmed with device manufacturer, and it seems to be problem from apple side. Any help will be appreciated, Thank you.

Hello, I'm trying to add matter devices to home kit. It end up saying as "Unable to add accessory" Using: Home Pod Mini Version:16.6 Model: MJ2E3 IOS version: 16.6

I have tried to add Meross matter plug but still pairing failed, it reported always same error. error: related decl 'e' for HMErrorCode(_nsError: Error Domain=HMErrorDomain Code=18 "Pairing Failed" UserInfo={NSLocalizedDescription=Pairing Failed, NSUnderlyingError=0x281503cc0 {Error Domain=HAPErrorDomain Code=3 "(null)"}})

when using these IOS matter source SDK on IOS phone to setup matter device , could we do it without homepod or apple TV? just using IOS matter app.

I can bind the light bulb to the light switch through chip-tool software But when I added the light bulb to the apple home app, I noticed two problems (1) The light switch is displayed as an unsupported accessory, note that it is an unsupported accessory, not an uncertified device, because the light bulb can be normally added to the home app and is only displayed as an uncertified device (2) If the light switch can be added to the home app, then I do not know how to bind the light bulb to the light switch
