Abstract: Synchronizing devices in a network. In one example, a first communication interface of a first communication device transmits a first message through a first communication path in a mesh network. The first communication path includes the first device, a second device, and a remote server. The first message includes a status of the first device. The first communication interface is switched to a sleep mode after transmission of the first message. Subsequently, the communication interface switches from the sleep mode to an awake mode. While the first communication interface is in the awake mode, the first communication interface transmits a second message through a second communication path in the mesh network. The second communication path includes the first device, a third device, and the remote server.

Abstract: Methods and systems of extending battery life of remote battery-operated timekeeping devices by minimizing the number of required synchronizations per unit of time needed to maintain a predetermined accuracy of the devices. The number of synchronizations are minimized by first calculating a time error rate between the remote timekeeping device and a master device over a sample period. Then, a synchronization is delayed and the remote timekeeping device is compensated based on the time error rate. The compensation delays the need for a synchronization yet maintains the predetermined accuracy of the remote timekeeping device. In some embodiments, the remote timekeeping device is compensated and multiple synchronizations are delayed before a new synchronization is necessary to maintain the predetermined accuracy.
