wanda home automation app

Research and problem definition

Project goal

Create a unique experience that provides comfort and confidence through a mobile app. To do this, we need to design the interface of an app that facilitates the user’s access and comfort in their homes, giving control not only to themselves but to the whole family.

*Please, be aware that all information in this case study is my team’s: Mauri Aguirre, Maria Abeledo, Mireia Serra, Guillermo Garcia and me.


Conducting User Survey

We conducted a user survey to gain user insight and gather ideas to reach the goal of the project. 

We wrote a 20-question survey and posted it on different online communities and Facebook groups that matched the target user profile. We received 96 responses.

We also did market research by analyzing the reviews of users from our competitors’ platforms. We found a relevant amount of data in various e-commerce shops such as Amazon.


  • 90% would like to receive regular advice from the app to save energy at home. Solution: include a screen with current energy spending and allow the user to set goals & receive tips to decrease energy spending.
  • 86% would like to control the temperature of their homes remotely. Solution: add a thermostat feature that can be controlled remotely.
  • 75% would like to control the temperature of the different rooms in their homes separately. Solution: allow controlling room temperature separately in the thermostat feature.
  • 55% would prefer the fingerprint as the method to open a smart lock to their homes. Solution: include a smart lock feature that is secured with the fingerprint.

User personas

We created and validated two persona profiles by using the results obtained from the survey and the review analysis from competitors.

Focussing especially on the interactional context of both personas, we could better understand their environmental, physical and emotional state when interacting with our app. This helped us make important design decisions and determine key functionalities like the following ones:

  • An initial tutorial that will guarantee a good understanding of the apps functioning to all types of users (the more techie and fewer techie ones).
  • Chat function with customer service for technical assistance.
  • Daily graphs that will inform users of their current energy consumption.

Design impact

Basic app features based on research conclusions


The users will be able to connect their devices to the app to access movies, series, music and will also be able to control the children's access to multimedia content.


The thermostat feature will enable users to control the temperature of the different rooms in their homes separately and remotely. Also, the app will provide feedback to ensure responsible use of energy at home.


Users will be able to give others access to their home remotely and whenever they want (one-time access or total access). Access will be granted via fingerprint or directly with a one-time code through the app.

User Flow

Flow diagram to map every step of the user interaction to achieve the goals of the app: grant access to the home (lock), control the temperature of the different rooms (thermostat), and view multimedia content (multimedia).

Design exploration

Ideating solutions

Low-fidelity Wireframes:

We sketched each iteration and added the necessary elements and screens so that users can reach their goals within the app. The low-fidelity Wireframes were made with Miro, and after being tested with 5 users we designed the mid-fidelity Wireframes with Figma.


Mid-fidelity Wireframes:

We used Figma to design the mid-fidelity Wireframes and create the app’s prototypes.

About the project

During my UX/UI master’s degree, my team was given the challenge of designing a home automation app that would allow controlling different IoT devices via the smartphone.
