This will be a yaml file containing the zone and fan definitions
with the associated set of parameters that feed into the control
algorithm. Currently this contains the zone number, the zone initial
speed, and the list of fans(including their inventory path, sensor
name, etc...).<br>

Correct, that will be the case here as well.<br>

Filling out the associated yaml file for the control application
defines how the algorithm will control the fan speeds based on the
values, sensors listed, delays, etc.. that will be supported as
parameter inputs to the algorithm.<br>

This will be configurable by the yaml file where the fan speeds are
set on the zone, which a zone is a group of fans. These zones can be
constructed as 1-to-many fans enabling individual fans being
controlled or a group of fans being controlled similarly.<br>

As Patrick mentioned a few of us have been working on the
fan control infrastructure currently and wrote up a quick
outline to share our thoughts on the design layout. Let us
know if there are areas you'd like to see more detail.<br>
