Contrôle de l’accessoire

import HomeKit

// Get the PowerState characteristic through the LightBulb service let lightBulbOn = lightBulb?.services.first(where: { (service) -> Bool in service.serviceType == HMServiceTypeLightbulb })?.characteristics.first(where: { (characteristic) -> Bool in characteristic.characteristicType == HMCharacteristicTypePowerState })

Lecture d’une caractéristique

// func readValue(completionHandler completion: @escaping (Error?) -> Void) // var value: Any? { get } lightBulbOn?.readValue(completionHandler: { (error) in if let error = error { // Handle the error } else if let isOn = lightBulbOn?.value as? Bool { print("Light bulb is \(isOn ? "ON" : "OFF")") } })

Ecriture d’une caractéristique

// func writeValue(_ value: Any?, completionHandler completion: @escaping (Error?) -> Void) lightBulbOn?.writeValue(false, completionHandler: { (error) in if let error = error { // Handle the error } else { print("Light bulb is OFF") } })

Notifications

// func enableNotification(_ enable: Bool, completionHandler completion: @escaping (Error?) -> Void) lightBulbOn?.enableNotification(true, completionHandler: { (error) in if let error = error { // Handle error } else { print("Notifications are enabled") } }) class AccDelegate : NSObject, HMAccessoryDelegate { public func accessory(_ accessory: HMAccessory, service: HMService, didUpdateValueForCharacteristic: HMCharacteristic) { if let isOn = characteristic.value as?
