Why do devices that Matter over WiFi still need homepod mini for control? Can't the home app communicate directly with the device. How to get devices that Matter over Thread to join the HomePod Mini's Thread network. Do you need any additional conditions? As for the Matter Bridge, is the Home app still unsupported now? Can the future plan be announced？

I don't find any API documentation of the Matter.framework. Is it going to be private or can we use it to create custom controllers, which are independent of HomeKit?

Hello, I make a matter matter device with Onoff function. I add the mode select cluster in device to set work mode of device. I can not find the work mode in Apple Home application, only the onoff switch shows in UI. I tested my device with chip-tool, and read out the mode from device. B.R. Joe

Hello, apparently, HMAccessorySetupManager.performMatterEcosystemAccessorySetup has been removed from HMAccessorySetupManager.h. Is there any more information on this? Has it moved to a different Framework, or has this kind of functionality ("setting up Matter accessories with a Matter Partner Ecosystem App") been removed from iOS?

Hi, Was anybody able to connect Matter device with iOS 16 phone? I've tried ESP32 board with m5stack. The ESP32 device was in commissioning mode, but Apple Home app was not recognising it (neither by QR code nor as nearby device).

In the Xcode 14 Release candidate, I get a No such module 'Matter' error when attempting to import Matter. Has Matter been removed from the iOS 16 RC? What are my options other than waiting for an iOS 16.1 Beta?

Hi, The WWDC2021 Video Add support for Matter in your smart home app has a bunch of code examples referencing APIs that are no longer present or deprecated, e.g. this one. Unfortunately the documentation doesn't give any hint on the replacement APIs. Most of them are to be found in HMMatter* objects. But in the video at 14:27 an API for CHIPDeviceController is shown. Unfortunately that one cannot be found anymore. Does anybody know how to achieve the described task (managing state and control of a matter accessory)

I'm looking for a tutorial or documentation on HMMatterRequestHandler. I'm aware of the brief mentions in wwdc21-10298 but it's not sufficient. Is there any tutorial/ more extensive documentation?

I'm trying to commission a matter device via HMAccessorySetupRequest.performMatterEcosystemAccessorySetup. After scanning the QR code via the system provided UI the app shows a system popup: Additional Setup Required This accessory required additional setup. Refer to the manufacturer's guide for more information Unfortunately there's no further information. Did anybody succeed in using this API and could assist?

Hi, I commissioned an ESP32C3 device running Matter using the Home app. The iPhone is on iOS version 16 beta 2. For this I used the all-clusters-app/esp32 example from the connectedhomeip repo. Commit ID for connectedhomeip: cfc35951be66a664a6efdadea56d1b8ea6e63e96 I cannot on the accessory screen see any option to create matter groups. Is there any such option available on the home app? Thanks, Ajay Gantayet
