Smart Room Sensors

Don’t forget to take account of the remote sensors that come alongside the thermostat. Remote room sensors help to create temperature zones using a single thermostat. Apart from creating a more comfortable environment for your home by making adjustments to your rooms or by detecting the humidity in your home and keeping it in check, they ensure that your home has a balanced temperature based upon the areas in your home you care most about. 

The sensors also have an algorithm that detects the difference between someone just passing by or someone spending time in a certain room. Cool right? So having detected these key rooms that are often used the sensors ensure that these room’s temperatures are per your comfort level.  And you can connect up to 20 sensors in your home. 

And don’t stress about getting them powered because you can power them with two triple-A batteries on each sensor and they can be placed as high as 200 feet.

Its touch navigation on the device is well designed, easy to adjust your temperatures and it also comes with the option to view your outside temperature and even the remote sensor temperature and humidity level.

With this system, your thermostat will actually know when you are at home or away, or even when you are coming back home so that it can ensure that your place is pre-heated or pre-cooled to your comfort level before you arrive. 

You can also control your temperature with ‘goodnight’ or ‘good morning’ routines or if you feel that’s too much of a hassle you can automate other connected devices based upon your preferred temperature to have the thermostat turn off when the doors are left open or turn on your routines.
