App Interface Intro

The interface was revamped in order to accommodate the additional products. The visuals were updated to a modern look and feel, while the app architecture has been modified to accommodate more products and a setup flow that makes the setup process easier and faster.

Power Outlet Front View

For the plug, we wanted a design that drew upon Nest's current product line while at the same time stayed within the confines of what is expected from a power outlet. With rounded corners and a smooth surface the product is aesthetically refined, conveys a high level of technological sophistication, and is non-threatening to the end user.

Device Integration
Since the Nest Power device features the same connectivity as the thermostat and fire alarm, the devices can connect to one another in order to provide a home automation solution that can do a lot more than the individual devices could do on their own.

Mission Statement


Creating an intelligent home by modernizing and connecting all aspects of power consumption and providing the user with a new level of control over energy management.


Developing a smartphone and tablet interface that gives users seamless control over power management in the home.

Energy Data
Power Consumption Graph

"Energy consumption will grow by 56 percent between 2010 and 2040"

- Energy Information Administration

The Environmental Defense Fund is involved in five Smart Grid development partnerships across the country.

Smart Grid States

"The problem, so far, is that technological advances in our electrical grid have tended to benefit the utilities more than the consumer."

- Intelligent Utility

The fact that all improvements to the power infrastructure are benefitting the utilities and not the consumer represents a huge opportunity for Nest.

Home Integration
Electrical Wiring Diagram
Because of the variation in electrical wiring between different homes, each device should interface with the wiring as far down the line as possible. This setup gives the user the maximum amount of control.


Understanding the Big Picture
We needed to understand where the products fit within the greater picture of energy consumption and management.

Once we understood the logistics we needed to make sure that the best location for the devices was at the wall outlet.

User Journey Map
Following the decision to stick with the wall outlet as the location for the device, we defined a user journey map that we wanted to achieve with the device-application combo.

Application Architecture
The next step was to layout an application architecture that could not only accommodate the existing product line, but also allow the addition of any future devices.
Application Architecture
We divided the app into two distinct sections. The first would be the setup process, which followed a very linear architecture in order to keep the process as simple as possible. The second one would allow the user to view consumption, schedule devices, and get complete control over their power usage.
Usage Application Map
Interface Testing
Our next step was to come up with a wireframe for the app. Once we got the wireframe ready we did some user testing by using POP, InVision, and Silverback. We took the feedback we got and adjusted the wireframes as needed.

Hardware Proof of Concept
We also decided that it would be good to do a proof of concept for the hardware to make sure that what we were proposing was technically feasible. For this we turned to an Arduino micro controller in order to layout the device's electronic components.
Hardware Proof of Concept
Final Hardware
The final look of the hardware was CADed using Rhinoceros 3D. We decided to incorporate very soft features and radii. This brought the same design language to the new product as was used in the others.
