Abstract
A method and device includes the use of multiple remote sensors transmitting temperature information to a thermostat, while reducing or eliminating transmission interference and providing increased user control. Remote temperature sensors of the present invention sense temperature at variable time periods and only transmit temperature information on a sensed change in temperature. Transmission of temperature information is provided on variably selected frequencies within a specified range, and may be based in part on previous temperature transmissions. A learn mode is provided that allows for recognition of each sensor by a host-controlling thermostat, including determining the proper transmission power level for each sensor. Additionally, each sensor is programmable to provide a temperature offset and each sensor may be individually weighted according to specific requirements or needs.
