Use Case
AI Smart Home Control on Your Wrist
Demi controls your smart home, car, and IoT devices from your Apple Watch. One assistant for lights, thermostat, locks, and Tesla — all by voice.
The Problem
Smart home control is fragmented. Lights are in one app, thermostat in another, locks in a third, and your car in yet another. You end up with 6 apps just to manage your home. And voice assistants like Alexa only work when you're near a speaker.
How Demi Solves It
Connect your devices
Link your smart home platforms — Home Assistant, SmartThings, Tesla, and more — to Demi.
Control by voice
Say "Turn off the lights" or "Set the thermostat to 72" from your wrist, anywhere.
Create scenes
Tell Demi "When I leave home, lock the doors and turn off the lights" — and it creates the automation.
Remote access
Control your home from anywhere via your Apple Watch. No need to be on your home WiFi.
Key Features
Universal Control
One voice interface for all your smart devices — lights, thermostat, locks, cameras, and vehicle.
Wrist-Based Access
Control your home from your Apple Watch, anywhere in the world. No phone, no speaker required.
Smart Scenes

Presence Awareness

Energy Monitoring
Track energy usage patterns and get optimization suggestions to reduce your bills.

Integrations
