expose fan smart mode as HomeKit thermostat

[jmissig]

Rather than controlling my fan speeds directly, I'm perfectly happy to have my Haiku fans be in smart mode. What I would like to control about my fans is which temperature the smart mode is targeting.

Is it possible to read the fan's current temperature? If so, would it be possible to expose the fan's current temperature and ideal/smart set point as a thermostat in HomeKit instead of (or in addition to) a fan?
