HomeKit Device Pairing

Smart Life App SDK enables HomeKit devices to be compatible with both Tuya’s and Apple’s ecosystems based on the following capabilities. Users add devices locally in Apple’s Home app, and the devices can be simultaneously bound with the Tuya IoT Development Platform.

Functional description

ThingSmartAppleDeviceKit includes the HomeKit data for Apple’s Home app. It provides the capabilities to connect Apple devices to the Tuya IoT Development Platform. This way, your project can quickly integrate with Apple’s HomeKit framework. Simple API methods can be called to bind Tuya-enabled devices and query device information.

Class	Description
ThingSmartHomeKitPermissionUtil	Query the status of HomeKit-defined permissions.
ThingSmartHomeKitUtil	Query and manage the HomeKit homes and devices.
ThingSmartHomeKitConfigUtil	Pair HomeKit devices.
ThingSmartHomeKitDeviceService	Provide cloud APIs for HomeKit devices.
ThingSmartHomeKitDevice	Query and update HomeKit device features customized by Tuya.

The following operations are supported:

• Add devices: Bind devices with an iPhone.
• Bind devices: Bind devices with the Tuya IoT Development Platform.
• Remove devices: Remove devices from Tuya’s app or the Home app. Only the binding status is cleared.
• Reset devices: Reset a device. For example, users can press and hold a socket key or turn on a light consecutively three times.

Query permission status

API description

typedef void(^ThingSmartHomeKitPermissionCompletionHandler)(BOOL granted, HMHomeManager * _Nullable manager);

- (void)checkHomeKitPermissionWithCompletionHandler:(ThingSmartHomeKitPermissionCompletionHandler)completionHandler;

Parameters

Parameter	Description
completionHandler	The result callback. The permission status and current homeManager are returned.

Example

Objective-C:

self.permissionUtil = [[ThingSmartHomeKitPermissionUtil alloc] init];
[self.permissionUtil checkHomeKitPermissionWithCompletionHandler:^(BOOL granted, HMHomeManager * _Nullable manager) {
        if (granted) {
            NSLog(@"HomeKit Permission is on");
        } else {
            NSLog(@"HomeKit Permission is off");
        }
    }];

Swift:

let permissionUtil:ThingSmartHomeKitPermissionUtil = ThingSmartHomeKitPermissionUtil()
permissionUtil.checkHomeKitPermission(completionHandler: { granted, manager in
        if granted {
            print("HomeKit Permission is on")
        } else {
            print("HomeKit Permission is off")
        }
    })

Load HomeKit data

API description

After you create an object of home manager, HomeKit queries a list of homes and objects from the HomeKit databases. For example, the objects room and accessory are returned.

During the query, the primaryHome property of home manager is nil and the homes property is an empty array. Your app must process the home to be created after HomeKit initialization.

typedef void(^ThingSmartHomeKitDataCompletionHandler)(HMHomeManager * _Nullable manager);

- (void)homeKitDataCompletionHandler:(ThingSmartHomeKitDataCompletionHandler)completionHandler;

Parameters

Parameter	Description
completionHandler	The callback to invoke when data is loaded.

Characteristics

Parameter	Description
devId	The device ID. Only an associated device has the value.
productID	The product ID of the device.
