Product-specific buyer note

Buy exact SNZB-04P, not the older SNZB-04 and not a two-pack or kit. A Zigbee coordinator is mandatory and excluded. Check the 20mm maximum gap, alignment and adhesion on the actual frame; nearby metal can reduce radio or magnetic reliability. Do not assume a specific internal reed-switch design because official customer discussion reports hardware revision. India price excludes GST. Confirm landed total, included CR2477, invoice, stock, hub feature exposure and local warranty before ordering.

India regulatory note

Use an India-approved Zigbee coordinator and permitted radio configuration. This indoor contact sensor is not a certified intrusion-alarm or life-safety device. Coin cells are an ingestion hazard; secure and recycle the CR2477 responsibly. Test every security automation periodically and retain a manual or independent fallback.
