A processor and power broker for controlling the obtaining, distribution and usage of electrical power for electronic devices such as peripherals of thermostats. Sources of power may incorporate batteries, energy harvesting modules, energy storage capacitors, and power lines. The power broker may maintain charge on the capacitors, operate the energy harvesting modules, control usage of the batteries, and utilize power line sources when available. Loads such as the peripherals may need to request approval for energy usage. Energy usage and conservation may be managed by the power broker according to a power scheme. A power scheme may consist of a set of rules as to how energy usage by the peripherals is to be managed. The rules may also indicate as to how the energy sources are managed.

Power broker module

An equipment interface module that can operate one or more pieces of HVAC equipment in accordance with instructions received from a properly operating thermostat, yet can also operate the HVAC equipment when communications between the thermostat and the HVAC controller are lost due to, for example, low battery power at the thermostat, malfunctioning thermostat sensor(s), malfunctioning communication and/or thermostat circuitry, electrical interference, and the like. In some instances, the equipment interface module may regulate the HVAC equipment in accordance with a signal from a remote sensor when communication with the thermostat is lost.
