Whereas Nest’s $249 (£185/AU$330 transformed) third-generation Studying Thermostat ($255.00 at Amazon.com) does not deviate wildly from earlier iterations, this mannequin has a bigger display and a slimmer profile, in addition to a few new options. Particularly, it has a brand new sensor that is higher at selecting up your presence from a distance to show the time, indoor temperature or present climate forecast. It helps voice integrations with Google Assistant and Alexa, too. 

It additionally works with Nest’s temperature sensor, launched in 2018, roughly three years after this thermostat first hit shops. The temperature sensor is obtainable bundled with the thermostat for $19 ($268 whole), and bought individually for $39 every. Stick one in your child’s bed room, the basement — or some other spots which may run notably scorching or chilly — so you should use them because the default temperature readings on your house (relatively than your thermostat’s built-in temperature sensor). 

Like the unique 2011 Nest Studying Thermostat, this one depends on built-in sensors to trace your whereabouts together with algorithmic smarts to create a customized, auto-adjusting temperature schedule primarily based on whether or not you are at house or away. You may nonetheless make guide tweaks to your settings on the thermostat itself — or on the Nest app wherever you will have a Wi-Fi or mobile connection.

However these once-revolutionary options at the moment are par for the smart-home course, with manufacturers like Ecobee and Honeywell providing good thermostats of their very own designed to compete alongside Nest within the DIY market. 

The Nest Studying Thermostat remains to be price sturdy consideration, however the Ecobee4 works with Google Assistant, Alexa and Apple HomeKit — and it comes with a temperature sensor — all for $249.


You understand how your smartphone does not look dated till you catch a glimpse of the next-gen mannequin? That is precisely how I felt after seeing Nest’s newest Studying Thermostat. No, it is not a large departure from previous iterations. You may nonetheless get that very same rounded design and acquainted show type. However, there are a couple of key modifications.

Now you can select from amongst 4 completely different dial finishes, all for a similar worth — stainless-steel, black, white or copper. Nest’s third-generation thermostat additionally has a 40 % bigger display and an improved decision for higher all-around visibility. (Particularly, the show has 229 pixels per inch; that is 25 % greater than its predecessor, which ought to make for a sharper on-screen picture.) And, Nest slimmed down the thermostat’s profile so it will not stand out from the wall as a lot.

Whereas I seen the up to date show dimension and backbone immediately, the “thinner” depth was a lot much less apparent. A side-by-side spec comparability exhibits that the second-gen Nest measured Three.2 inches in diameter (eight.1cm) and 1.26 inches in depth (Three.2cm). The brand new thermostat is a contact greater at Three.Three inches in diameter (eight.4cm), however slimmer with a depth of 1.21 inches (Three.1cm).

That tiny zero.05-inch distinction in depth actually does not make a lot of a distinction visually, however Nest is clearly working to streamline its thermostat with every next-gen product launch. 

Nest temperature sensors value $39 every, or $19 bundled with the $149 Studying Thermstat.

The third-gen Nest Studying Thermostat additionally presents a handful of recent options. The place earlier Nest thermostats relied on near-field sensors alone (which have a roughly Three-foot vary) to choose up on movement exercise, this model tacks on a far-field sensor for a brand new perform it calls Farsight. Farsight picks up your presence from farther away than earlier fashions, then it allows you to see your thermostat’s goal temperature or the present time in both “analog” or digital modes from as much as 20 toes away. This ensures that you could spot the time and temperature at a distance, with out having to be on high of the Nest. And, due to the brand new and improved decision and bigger show, you may truly be capable to learn them.

The Studying Thermostat, in addition to the Nest Thermostat E, now work with Nest temperature sensors. Not like Ecobee temperature sensors, which have proximity detectors to assist decide if you happen to’re house or away, Nest’s model solely tracks ambient temperature. In addition they do not at present assist voice instructions, comparable to, “Hey, Google, what temperature is it within the kitchen?”

You may put as much as six Nest sensors in your house and each is powered by a single CR123 battery that is alleged to final for 2 years. Set up takes a couple of minutes — simply pull out the battery tab, enter the code on the sensor, watch for it to attach and assign it to a sure room like “Kitchen,” or “Grasp Bed room.” 

After that, you possibly can assign one of many sensors to behave because the default temperature studying from the app. You may also create customized schedules for the morning, noon, night and evening from the “Handle sensors” part within the app settings menu.

For instance, if you happen to recurrently cook dinner within the night, stick a temperature sensor in your kitchen. Since that room/space doubtless will get hotter throughout that point, you possibly can set the “Kitchen” sensor to be the default temperature studying between four and 9 p.m. each evening. That approach, your heating and cooling will alter across the temperature within the kitchen, relatively than the decrease temperature the place your thermostat is positioned.

Nest’s Studying Thermostat additionally presents Household Accounts and Dwelling/Away Help, two new options that assist enhance efficiency. Household Accounts lets customers in the identical family arrange their very own Nest accounts (as a substitute of the shared household accounts that the corporate provided beforehand). As soon as Household Accounts are created, Dwelling/Away Help jumps into motion by monitoring every individual’s telephone location. It is not precisely the identical as geofencing, as there is no geofenced vary, however it does make it even simpler for Nest to control your whereabouts.
