Hey everyone! I built a Home Assistant add-on to solve a problem I think many of us have: “Where did I put that thing?” I know there are other tools out there that do this, but the ones I found were packed with so many features — I just wanted something simple.
WhereIsIt is a physical storage management system that runs entirely inside Home Assistant. Organize your stuff into Units → Boxes → Items, slap a QR code on each box, and never lose track of anything again.
Features
- Hierarchical Storage — Create storage units (Garage, Attic, Closet), add boxes inside them, and track items in each box
- QR Code Labels — Generate and print QR codes for your boxes. Scan them with the HA Companion App to instantly see what’s inside
- Powerful Search — Find any item or box instantly with full-text search and category filters
- Category Management — Organize items into categories with a color-coded management screen
- Item Photos — Take a photo of items for visual identification
- Mobile-First Design — Built for the HA Companion App with a responsive Material Design UI
- Runs Locally — Everything stays on your HA instance. No cloud, no accounts, no subscriptions
How it works
- Create a Storage Unit (e.g., “Garage Shelves”)
- Add Boxes to it (e.g., “Box #1 - Christmas Decorations”)
- Add Items with descriptions, quantities, categories, and photos
- Print the QR code and stick it on the physical box
- Months later, scan the QR code → instantly see what’s inside
Tech Stack
- Frontend: Lit + Vite (Material Web Components)
- Backend: Python + FastAPI + SQLAlchemy
- Database: SQLite (persistent, no setup needed)
