1. A method of using a remote server to manage a wireless power transmission system, the method comprising:

  • at a remote server that is in communication with a plurality of power transmission managers, a first power transmission manager of the plurality of power transmission managers configured to control a first wireless power transmitter and a second power transmission manager of the plurality of power transmission managers configured to control a second wireless power transmitter;

    receiving, from the first power transmission manager, information identifying a first electronic device that is associated with a first receiver, wherein the first electronic device is located closer to the first wireless power transmitter than to the second wireless power transmitter and the first electronic device has requested wireless power from the first wireless power transmitter;

    receiving, from the second power transmission manager, a status report that includes information identifying a current or forecasted charge level for a second electronic device associated with a second receiver, wherein the second electronic device is located closer to the second wireless power transmitter than to the first wireless power transmitter;

    in response to receiving the information identifying the first electronic device;

    determining, based at least in part on the information identifying the first electronic device, whether the first electronic device is authorized to receive power from the first wireless power transmitter; and

    in accordance with a determination that the first electronic device is authorized to receive power from the first wireless power transmitter, transmitting instructions to the first wireless power transmission manager to cause the first wireless power transmitter to transmit power waves that constructively interfere proximate to the first electronic device;

    in response to receiving the status report;

    determining whether the information identifying the current or forecasted charge level indicates that the second electronic device requires charging; and

    in accordance with a determination that the information identifying the current or forecasted charge level indicates that the second electronic device requires charging, sending, to a user associated with the second electronic device, an alert (i) indicating that the second electronic device requires charging and (ii) prompting the user to request wireless power.
