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.

主权项

1. A thermostat comprising:
a controller configured to control the thermostat; a thermostat power source including an internal power source; a power supply circuit configured to receive power from the thermostat power source; an energy level indicator for determining a remaining power capacity of the internal power source of the thermostat; a power supply sensor connected to the controller and configured to sense the thermostat power source; 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 greater than zero for enabling the wireless transceiver when the power supply sensor detects that the thermostat power source is the internal power source; 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.
