Battery Power Management in a Thermostat With a Wireless Transceiver

摘要

A thermostat includes a controller for controlling the thermostat, a battery supplying power for the thermostat, and a wireless transceiver for receiving control information from a remote device and for transmitting information to the remote device. The controller sets a default time schedule for enabling the wireless transceiver.

1. A thermostat comprising:
a controller configured to control the thermostat; a power supply circuit configured to receive power from one or more power sources external and/or internal to the thermostat; an energy level indicator for determining a remaining power capacity of an internal power source of the thermostat; a power supply sensor connected to the controller and configured to detect which of the one or more power sources is providing power to the thermostat; and a wireless transceiver connected to the controller, the transceiver configured to receive control information from a remote device for the controller, the transceiver further configured to transmit information from the controller to the remote device; wherein the controller is configured to set a time delay for enabling the wireless transceiver when the thermostat power source detected by the power supply sensor is internal to the thermostat; and wherein the controller is further configured to change the time delay to increase a time period between when the wireless transceiver is enabled as the remaining power capacity of the internal power source decreases.
