Systems and methods for re-commissioning a controlled device in a home area network
Systems and methods for preparing and re-commissioning a controlled device in a home area network are described. A utility meter is communicated with. An authentication key and encryption data for communicating with the utility meter may be determined. The authentication key and encryption data are sent to a controlled device. A set of translation rules for a message are determined. The translation rules are sent to the controlled device. The controlled device establishes a secure communication link with the utility meter using the authentication key and the encryption data. The controlled device receives a request to change power usage from the utility meter over the secure communication link. The controlled device translates the request to change power usage into control instructions using the translation rules.
