R200 Remote Control
By using the R200, you gain two-way control of you connected
devices. “Two-way” means that in addition to data being sent to
an electronic component (such as a Nest Thermostat), data I also
returned to your remote so you can see graphical information of
current status, including the current temperature in the home and
more. Adding the HomeSet Mobile App for Android™ and iOS
devices provides the same two-way feature.
