⚖️ Seller Warranty & Marketplace Dispute Conciliation

Warranty activation is indicated when the sensor exhibits functional failures that are not resolved after following all self-help instructions, such as persistent Zigbee communication failure without apparent cause, a reed switch defect that fails to detect magnet proximity even with a new battery and correct alignment, or internal manufacturing defects that compromise product use. Refer to the seller's warranty and marketplace return policy.
