# unblockAccessory(_:completionHandler:)

Unblocks a blocked accessory.

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

## Parameters

`accessory`

The accessory to unblock.

`completion`

The block executed after the request is processed.

- error: `nil` on success; otherwise, error object indicating the reason for failure.

## Discussion

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