Kit QR & NFC labels
Printable QR stickers and optional NFC tags encoding your ThermalTrace push ingest URL — onboard firmware without typing the key.
What it is
- Does: Puts the full ingest URL on a sticker (QR) or NFC tag (NTAG213/215 URL record) so phone or laptop can scan during flash / HA setup.
- Does not: Sell branded drop-ship labels from ThermalTrace. Print from the Devices QR callout (SVG download) or write NFC with any NDEF URL writer. Rotate the key if a sticker is lost.
Parts
| Part | Why | Buy |
|---|---|---|
| Waterproof label stock | Garage / utility room stickers for device name + QR. | Amazon label search |
| NFC NTAG stickers | Optional tap-to-open ingest URL on Android / iPhone. | Adafruit NFC · Amazon NTAG |
Setup
- Create or rotate a push key on Devices — QR is visible about 30 minutes.
- Download the SVG or print device name + QR + URL on waterproof stock.
- Optional: write the same HTTPS ingest URL as an NDEF URI record on an NFC tag. Keep tags with the kit, not on a public door.

Kit QR & NFC labels FAQ
What it does, what it does not replace, and how it fits ThermalTrace.
Does ThermalTrace sell QR stickers?
No. Download the SVG from Devices after create/rotate, print on waterproof labels, or write the ingest URL to an NFC tag. Guide: thermaltrace.dev/kit-labels.
Is NFC safe on a public door?
No. The tag holds the ingest URL. Keep labels with the kit or inside the utility room; rotate the key if one is lost.
How long does the on-screen QR last?
About 30 minutes after create/rotate on Devices. Re-open the callout or download the SVG if it expires. Walkthrough: thermaltrace.dev/about/kit-qr-onboarding.
