AI Summary

Rematters is a free add-on for Home Assistant that acts as a secure vault for storing and organizing Matter smart home device pairing codes. Instead of keeping QR codes in a drawer or taking photos that get lost, you scan them once and Rematters keeps them safe forever. You can organize codes into categories, print official-looking QR code stickers, and automatically back everything up to Google Drive. It also optionally syncs with Rematters Cloud so you can share codes with family members or access them from anywhere.

How It Works

1
🏠 You use Home Assistant for your smart home

You already have a smart home system running Home Assistant and want to keep your Matter device codes organized.

2
📦 You install Rematters from the add-on store

You add this repository to Home Assistant and install the Rematters app with one click, just like installing any other app on your phone.

3
📷 You scan or enter your Matter pairing codes

Using your phone camera, you scan QR codes from your Matter devices, or type in the 11-digit codes printed on the boxes. Rematters recognizes and saves them automatically.

4
You organize your codes your way
🗂️
Simple organization

Just add codes to categories and search by name or device type

🔗
Smart linking

Connect codes to Home Assistant entities so they update automatically when your devices change

5
🖨️ You print QR code stickers for your devices

Rematters generates beautiful QR code labels that match the official Matter style. You stick them on your devices or inside a drawer so you never lose a code.

6
💾 Your codes are automatically backed up

You connect your Google Drive account once, and Rematters saves a backup of all your codes every 24 hours. If anything happens, you can restore everything from the cloud.

🌐 Everything is safe and accessible

Your Matter pairing codes are organized, backed up, and ready to use whenever you need to pair a new device or help a family member connect to your smart home.

What is Rematters-HA?

Rematters is a home assistant add-on that serves as a vault for Matter pairing codes. If you have a home full of Matter devices, each one comes with a QR code or manually entered setup payload. This project stores those codes, organizes them by category with icons and colors, and lets you export or back them up.

The backend is Python running a FastAPI server that talks to Home Assistant supervisor. The management UI opens as an ingress panel inside Home Assistant. You can scan a new code with your device camera, or paste in the MT: QR payload. Once stored, the system generates printable QR stickers and pairing labels, links codes to HA entities to auto-sync values, and pushes backups to Google Drive on a schedule.

Why is it gaining traction?

Matter adoption is accelerating, and everyone building a HA-based hub needs a way to preserve setup codes for when devices get factory-reset or moved between homes. Rematters solves that pain directly. The QR scanning and sticker generation cover a real workflow gap that spreadsheets or Notes apps do not address.

The cloud sync is the differentiator. It is optional but enables linking codes to different HA instances, and the share cards let you send aQR code to someone without handing them raw YAML. The bidirectional merge handles edits across devices gracefully, with delete tombstones propagating correctly.

Who should use this?

Home Assistant users running Matter hubs who want to keep their device pairing codes backed up and labeled. If you have more than a handful of Matter devices and do not have a system for storing those codes, this is what you need. It is also useful for people running multiple HA instances who want code synchronization.

Verdict

With a 0.9% credibility score and only 16 stars, this is a young, niche project with no publicly visible test suite. The code quality looks solid but the community is essentially just the developers right now. If you are deep into Matter in Home Assistant, it fills a legitimate gap. Start with the ingress UI to validate it fits your workflow before relying on it for critical backups.
