用于控制智能家居概念的设备代表了系统与用户之间的界面。作为入门级恒温器，Nest 恒温器以其智能操作模式帮助用户节省能源。遵循最佳效率的原则，恒温器的形状基本上被设想为一个带有嵌入式盖子的碗。凸起的盖子不仅可以作为令人愉悦的设计细节，还可以在物理上保护镜头并有助于降低制造公差。这赋予 Nest 恒温器简约而迷人的外观。  辅以扩展的颜色选择，其优雅的外观与丰富的内涵和谐统一。恒温器经过精心设计，易于拆卸。与先前的恒温器型号相比，其零件更少、更加轻盈，塑料零件（包括内部零件）使用 49% 的使用后可回收树脂。Nest 恒温器提供高度先进的可操作性，用户通过直观的上下滑动控制与其自然交互。在雷达芯片的支持下，其智能运动检测同样令人印象深刻。例如，一旦用户靠近设备，将立即显示当前温度。Nest 恒温器易于编程，并通过节能查找器 (Savings Finder) 等功能提供广泛的节能选项。

Devices for controlling smart home concepts represent the very interfaces between the systems and their users. As an entry-level thermostat, the Nest Thermostat with its smart mode of operation is aimed to help users save energy. Following the maxim of optimum efficiency, the shape of the thermostat has been envisioned essentially as a bowl with an inset lid. The elevated lid not only works as a pleasing design detail, it also physically protects the lens and helps with manufacturing tolerances. This gives the Nest Thermostat a simple and inviting formal appearance. Complemented by extended colour options, it adopts an elegant look to harmoniously enrich interiors. The thermostat has also been thoughtfully designed for easy disassembly. Made of fewer parts and lighter than the predecessor thermostat model, it uses 49 per cent post-consumer recycled resin for its plastic parts, including the internals. The Nest Thermostat offers highly advanced operability by allowing users to interact with it naturally through an intuitive up and down swipe control. Supported by a radar chip, it also impresses with its intelligent motion detection. For example, the current temperature is thus immediately displayed as soon as the user approaches the device. The Nest Thermostat is easy to program and offers a wide range of energy-saving options through features such as the Savings Finder.
