Nest's smart heating system just got smarter. From today, you'll be able to pre-order the long-awaited Nest Temperature for $39 (a three pack costs $99) letting you get precise heat readings from every corner of your home.
While UK and Australian pre-orders have yet to open, that converts to around £25 / AU$50 and £70 / AU$125 for the single and three packs respectively.
A bundle that comes alongside the Nest Thermostat is set to launch in the spring, too.
- Best smart thermostat: heating your home using tech
You may be asking, if the smart thermostat itself can read ambient temperature, what's the need for an additional sensor?
Well, a thermostat only take a general reading from its immediate surroundings. So if you've got several floors to your property or a draughty corner, it may not be an accurate reflection of some colder or hotter corners of your home. With a set of the temperature readers, the thermostat can be programmed to favor the temperature in individual rooms – perhaps lifting the temperature for a cosy sleep in an icy bedroom, while lowering it at a time when the kitchen is generating lots of heat.
A replaceable CR123 battery keeps each sensor ticking over for as long as two years, but you'll yet to be able to get smart assistant integration for the sensors. You'll have to wait a bit longer before you can ask Alexa or Google Assistant for specific temperatures in specific rooms.
