Abstract: A networked display has multiple modes of operation. In the first operating mode, the display receives and shows information related to charging an electric vehicle. In a second mode of operation, the display receives and shows information related to home energy usage. Other operating modes may also be supported.

Abstract: A unique identifier may be stored in an RFID chip, a bar code, or other methods of passive storage associated with the networked light bulb. The unique identifier may be accessed while the light bulb is unpowered and before the light bulb is put into service. Information is stored in a database that identifies an association between the unique identifier and a particular network. If the light bulb is put into service, the light bulb may send the unique identifier over the network. A device may receive the unique identifier and query the database for information related to the unique identifier. If the unique identifier is associated with the particular network that the light bulb is connected to, the light bulb may be added as an authorized node on the particular network.
