The very first day my ac usage was 5 hrs. Down about 4 hrs. I created two zones by install a mini split downstairs and using my central air for upstairs by using the sensor. Upstairs cools quickly because my hvac is in the attic. Before using the sensor the system had to run much longer to cool downstairs. Problem solved.

Works absolutely wonderful in the bedroom. Only downfall is not being able to set a custom schedule for the sensors.

I would give this five stars, but I don’t like that I can’t set the times the thermostat uses the sensor. There are four preset blocks of time, and you can’t change them. Sweating in my living room as I type this because my furnace is getting my bedroom up to temperature. (9 PM to 7 AM block).

talk about a money saver, now my wife can see the temps around the house and set the main nest to balance the house out. the main nest, saved us so much money it is 5 star, but since dell is no longer selling these products the negative is on dell

I like the size and the sleekness of it, it’s about half (or less) the size of the actual nest which I wasn’t expecting. Super easy to set up too! Worked immediately to cool our bedroom down with our central air,
