What to verify before setup or purchase
- Check door preparation, dimensions and an emergency access method; do not expose pairing, PIN, home-key or access credentials.
- Regional variant remains unresolved; do not auto-recommend this as a verified US retail SKU.
Use the device label, manufacturer app and current official support article to confirm your US variant and firmware. For switches, locks and thermostats, also verify the physical installation requirements before buying.
