# unblockAccessory(_:completionHandler:)

Unblocks a blocked accessory.

## Declaration

```swift
func unblockAccessory(_ accessory: HMAccessory, completionHandler completion: @escaping @Sendable ((any Error)?) -> Void)
```

```swift
func unblockAccessory(_ accessory: HMAccessory) async throws
```

## Parameters

- `accessory`: The accessory to unblock.
- `completion`: The block executed after the request is processed.

## Discussion

Discussion A misbehaving accessory automatically becomes blocked. After that, all requests to the accessory fail. Use this API to explicitly unblock the accessory.
