Distribution of call-home events over time to ameliorate high communications and computation peaks in intelligent control system

摘要

The current application is directed to an intelligent control system that includes intelligent thermostats and remote servers that spread call-home events over time to avoid large peak computational and communications loads on intelligent-control-system servers. The spreading of call-home vents over time is effected by use of call-home splay values pseudorandomly generated for intelligent thermostats.

主权项

1. An intelligent thermostat within an intelligent control system, the intelligent thermostat comprising:
a processor; an electronic memory; a time-offset value stored within the electronic memory, wherein the time-offset value is randomly or pseudo randomly generated and stored in the electronic memory during a manufacturing process; and instructions stored within the electronic memory that, when retrieved and executed by the processor, control the intelligent thermostat to establish a communications connection to a remote server of the intelligent control system at a time offset from the beginning of a call-home period by the time-offset value.
