The founder wants a few frequently used controls close at hand without opening the full home app each time. The first version could start with one clear household routine, then define the devices and services it needs to connect.
T3 · On the wrist
Founders developing a wrist-based home-control product, working with the teams responsible for connected devices and existing home apps.
A portrait-screen T3 concept for a few familiar actions, such as checking and adjusting a selected room light. Keep the interaction small enough to belong on the wrist.

Keep the portrait layout focused and the controls easy to distinguish.

Select the app or gateway integration, account permissions and pairing experience.

Distinguish a requested action from a confirmed device state, including connection failures.
We would select a small set of actions and define how the user knows a command has worked. The existing home service determines the connection and permissions.
A T3-based portrait interface could send a selected command through an agreed app or gateway and show the returned state. The design is scoped to the chosen home system.
Define the use case. Build the prototype.
Try it with the team. Refine the first batch.

Open the room or action made available to this user.
Use a clear touch target to send the intended command.
Show whether the connected system confirmed the change.
