Hello,I have a class CLightBulb and it is defined as a accessory delegate:class CLightBulb: NSObject, HMAccessoryDelegateIn the “init?()” I set self as the delegate:m_lightBulb.delegate = selfAnd I override the “didUpdateValueFor” method as follows, but it is never invoked when I turn a lightbulb on or off from the Homekit app on another device (other than the one I am testing on) //_______________________________ // AccessoryDelegate: Update Characteristic Value // // //_____ func accessory(_ accessory: HMAccessory, service: HMService, didUpdateValueFor characteristic: HMCharacteristic) { var results: CResults print("******------> CLightBulb AccessoryDelegate: Update Characteristic View") results = CResults() if ((accessory == m_lightBulb) && (service == m_lightBulbService)) { switch characteristic.characteristicType { case HMCharacteristicTypePowerState: results = GetThePowerStateFromTheLightBulb(workComplete: { () in let delegate = self.m_delegate if (results.GetResultCode() != CResults.code.success) { // NOTE: The attribute value is incorrect for Philips HUE bulbs so we have to check the error description // to see if the reason for the error is that its unreachable. It's not really an error if its unreachable if (self.m_isReachable == false) { delegate?.lightBulbReachablilityChanged!(device: self, newState: self.m_isReachable) } else { delegate?.lightBulbEncounteredError(device: self, opResults: results) } } else { delegate?.lightBulbPowerStateChanged!(device: self, newState: self.m_powerState) } }) default: print("CLightBulb: Encountered unexpected service type in accessory characteristic update.") } } }But when I test my app on my phone, it doesn’t get called when I, say, turn the light bulb off from the Homekit app on my iPad. Do you know what I’m missing?

Does anyone know when a HomeKit accessory's uniqueidentifier changes? I thought they were constant, but I've noticed that they change.Thanks,Scott

Hello,When my app attempts to read the battery level or the low power characteristics it always gets an error. (HMErrorDomain error 12.) It happens with an Elgato Degree as well as with a Samsung motion sensor (the only accessories we have with battery services). The app can read the temperature and the status of the motion sensor, but it always fails when doing a "ReadValue" on the HMCharacteristicTypeBatteryLevel or ...BatteryLow characteristiccs.Apple's HomeKit app doesn't have the problem as I can see the battery level in the accessory details.Any ideas?Thanks!

I’m doing something rather simple, but the execution doesn’t stop at the “wait”, it just continues so the data is incorrect. In the output I see the “After wait” message before the “Read the power….” message, and when the method returns it has the initialization value instead of the correct one. Can you tell me what I’m missing? let dispatchGroup = DispatchGroup() dispatchGroup.enter()characteristic.readValue(completionHandler: { (error) in if error != nil { print(error!.localizedDescription) } else { powerState = characteristic.value as! Int print("CLightBulb: -->Read the power state. It is \(powerState) at " + Date().description(with: Locale.current)) } })dispatchGroup.leave()dispatchGroup.wait()print("CLightBulb: (After wait) The power value is \(powerState) at " + Date().description(with: Locale.current))
