This case study is an exploration, rethinking and redesigning of the Google Home app user experience and interface.

Disclaimer: This UX and UI exploration was based on my own long-term use of the Google Home app, as well as other Google and smart home apps.
Module 1 — Add / Profile / Home-name
This area wastes too much screen space between the plus-icon, the user-profile and the home-name which is a field that is not a user priority. 
The home-name should be smaller and tucked away on the top left of the app.
Module 2 — Home controls
These home controls contain a lot of items that are secondary. 
Move these controls under a main-menu option. This will open up space for device-view.
Module 3 — Room and devices
Room and device layout are stacked in a way that takes too much space from the main view. 
Create a card layout to help better organize and categorize devices, save time and space and, making it easy for the user to quickly access devices. Also, rework primary actions to allow the user to quickly trigger devices to help save time. 
Module 4 — Bottom menu
The highlighted area is being generated by an oddly positioned microphone button, therefore unnecessarily wasting space. The drawer/tab section (home/events) offers limited use and seems disconnected. 
Replace the drawer section with a tab layout, moved to the top. Events gets moved as part of the new Home Control component. Replacing the microphone icon with the Google Assistant logo, permanently floating on the bottom right corner of the app. This allows the user to quickly trigger the assistant to save time. 
It takes the user too many clicks and much time to get to the target device.
Bring primary and secondary actions to the forefront on the homepage cards. 

Hard to scroll to devices that are in rooms at end of the scroll (sorted alphabetically).
Introduce a tab organizer to jump to the room and a sort function (a–z / recents). 

Icons and color palette don’t match Google’s ecosystem. 
Clean up UI elements and bring material icons to better tie in the Google Home brand with Google’s identity and simplify the user experience. 

All content is centered and stacked, making it hard to navigate and understand the hierarchy. 
Visually build a structural hierarchy to better prioritize components so the user can navigate more confidently.

Screen real-estate is poorly used and too much space is wasted. 
Redesign elements and components to provide a cleaner and more aesthetically app experience. 

App offers a messy and confusing user experience. 
Reorganize content to enhance and simplify the user experience. 

No dark mode present, making the app very agressive to the eyes at night or in dark surroundings. 
Introduce a dark mode to help reduce eye strain and make the user feel more comfortable. 

Fonts are sized and colored inconsistently adding to the confusing user experience. 
Use fonts in a more cohesive way to enhance the structural hierarchy.
Google has a lot of apps with a wide variety of elements to pull from in order to make a better Google Home user experience (UX), that also offers app wide consistency.
Created a card layout to help better organize and categorize devices, save time and space, making it easy for the user to quickly access devices. Also, reworked primary actions to allow the user to quickly trigger devices to help save time. 
No home is alike.

Introduce customizable device icon options from a design-consistent icon library allowing the user to feel more connected with their own Google home.

Added stroke weight to enhance icon contrast making it more accessibility compliant and easier for the user to identify.
