The Quilt system uses Wi-Fi (2.4 and 5 GHz) and Bluetooth to communicate between units and the remotes, and each Dial can also control the whole system, just like a thermostat does for a central HVAC system. The Dial has temperature, motion, and proximity detection built-in. You can also use the Quilt app (iOS or Android)

And I assume it also phones home to the mothership, which Hoovers your usage stats up for re-monetization?

Yeah, that’ll be a “nah, dawg” from me, well before even the astronomical price tag.
