The popular Thermostat Nest is entering its second iteration, aiming to provide a smaller devices while attracting more consumers. Nest is now thinner, with added compatibility features and the same price as the previous version.

The device is 20 percent thinner, sports a "mirror-finish" steel border, and is now compatible with 95 percent of low-voltage systems -an increase from the original version's 75 percent. The device now also knows when to enable heat or air conditioning, and it is also compatible with radiators.

"We thought we could make it even better," Head of Product Marketing at Nest Maxime Veron said to The Verge.

The outer steel ring of Nest is a controller dial and protection, separated in older versions of Nest. The original's open grille is also gone; instead, a front plate hides the sensors. A new backplate features more connectors, ensuring greater compatibility with heating and cooling systems available.

Alongside the hardware, Nest's software receives an upgrade. Version 3.0 is backwards compatible and introdcues System Match, which alters the software depending on the heating and cooling systems. Nest will recognize when users leave within as little as half an hour. Nest can also be programmed to heat and cool concurrently.

"We found people are extremely predictable, especially in the morning," Veron added. Users seem to need to be away from home for a period of time before Nest is confident it can disable heating and/or cooling features.

Mobile apps are updated to support version 3.0. The Android app now is designed for seven-inch tablets.

"We're going to make a lot of people very happy. When Amazon released the Kindle Fire, it really changed the landscape, and then the Nexus 7 came out ... these are the two we see taking off," Veron explained.

Spanish and French are also supported, and the mobile app now supports Android tablets.

Nest's 3.0 update is available now; the revised Nest itself is available for pre-order from $249, arriving in mid-October.
