Through recent updates in HomeKit integration for Philips Hue, I was excited to see they've integrated the Hue Motion sensor into the HomeKit ecosystem. When they integrated, I noticed each of those motion sensors also had a temperature sensor show up in my Home app. HomeKit support would allow integration of Hue temperature sensors and other 3rd party devices.
Here's a way that Flair's puck (even without the vents) can gain marketshare in the HomeKit space:
Motion/proximity sensing by specific user.
Flair has a valuable technology it could offer to the HomeKit ecosystem. Flair's Puck has the ability to identify a specific user by proximity.
This means, not only can I set my preferred temperature, I can control other devices with my specific preferences. Other members of my household could also have their preferences set.
In partnership with Apple, Flair could help create new features for HomeKit: User Hierarchy.
Once we have user preferences set up, a hierarchy could be created... In my house, my settings would always win.
Why is this worth the effort? Considering what ELSE it can do for me, Flair's Puck is rather expensive. Flair's Puck costs $99 versus the much cheaper Ecobee Remote Sensor at ~$35 or the Hue Sensor at $40. Opening the platform would increase the perceived value in Flair's Puck because could be used in the HomeKit ecosystem. I'd buy more Pucks if it could add such functionality to my HomeKit system.
