Abstract: A mobile device logs in to an authorization server, via a mobile device network communication interface, over a secondary network. The mobile device receives, via an image sensor, over a light communication band, a respective verification code. In response to logging in to the authorization server and receiving the respective verification code, the mobile device transmits, via the mobile device network communication interface over the secondary network, the respective verification code to the authorization server. In response to transmitting the respective verification code to the authorization server, the mobile device obtains, via the mobile device network communication interface over the secondary network, an authentication approval to control a plurality of RF nodes over a local wireless communication network.

Abstract: Disclosed examples offer ways to manage dialogues between radio frequency-enabled devices and conserve energy of the devices. A system includes a plurality of radio frequency-enabled nodes networked to communicate with a radio frequency-enabled device. The radio frequency-enabled device includes a radio frequency transceiver and a processing device. The processing device is configured to, in response to expiration of a time period or an occurrence of an event, transition the radio frequency-enable device from a standby mode to a transmit mode. In the transmit mode, a start dialogue message is broadcast. After a pause of a predetermined length following the transmission of the start dialogue message, the radio frequency-enabled device transitions to a receive mode to receive a data packet transmitted from one or more of the radio frequency-enabled nodes. Upon completion of receiving the data packet, the radio frequency-enabled device transitions from the receive mode to the standby mode.
