## Discussion

Discussion Use this method to add accessories that have already been deployed (for example, accessories that have HomeKit support added as a firmware update), or accessories for which scanning a QR code would be difficult. Your app provides the accessory’s HomeKit code using a setup payload. For details on the payload’s content, please join the MFi Program. During this process, the user assigns the accessory to a room and configures its services.
