Introduction
TOMMY transforms ordinary Wi-Fi devices into motion and presence sensors that detect occupancy through walls and obstacles. Easy to install and integrates with Home Assistant or Matter.
Key Features
- Through-wall sensing: Occupancy is sensed through walls and obstacles, allowing devices to be hidden in closets, cupboards, or anywhere out of sight
- Flexible zone coverage: Create zones that span your entire house with a few devices, or divide areas like "upstairs" and "downstairs" regardless of room boundaries
- Direction-free setup: Unlike traditional sensors that need to "look" at specific areas, Wi-Fi sensing monitors the entire area within a zone without requiring careful positioning or aiming
- No hub required: TOMMY runs as a Home Assistant add-on or on a Linux host (Docker) and uses supporting devices to create a sensing network
- Privacy-focused: Runs entirely locally on your network and does not require any internet connection. No data leaves your home
