What to verify before setup or purchase
- Installation safety: confirm manufacturer wiring/load/voltage guidance; use a qualified installer where required. No wiring modifications are prescribed by this dataset.
- 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.
