Abstract
Described herein are systems and methods for maintaining a wireless connection to a remote server while a device is in a low power mode. As a result of maintaining the connection, the device can receive messages triggering a wakeup event and placing the device in a normal power mode, enabling the device to be controlled remotely. To maintain the connection, the device transitions from sending encrypted network messages to a server from a first interval while in the normal power mode to a second interval while in the low power mode. In addition, the device sends unencrypted network messages to the server at the first interval using low power circuitry. The low power circuitry receives messages from the server and may trigger the device to enter the normal power mode and/or a connection maintenance mode.
