Hardware specification audits of this Evernary Wireless Smart Mailbox Alarm reveal a Tuya-ecosystem white-label chassis. The system architecture involves a 433MHz bridge to an AC-powered gateway that facilitates a 2.4GHz Wi-Fi transition. Technical audits indicate that the sensor relies on a CR2032 lithium cell, with performance metrics showing rapid voltage drops in environments where temperatures fall below freezing. The lack of rubber gaskets on the battery enclosure increases the risk of water ingress under standard outdoor exposure.
Connectivity latency is high due to the mandatory cloud dependency of the Tuya Smart infrastructure. Signal collision is a documented risk in high-density RF environments. Internal audit suggests that the advertised IP65 rating is not supported by the physical seal design found in the transmitter housing.
The YoLink Long-Range Wireless Smart Motion Detector is recommended as an alternative for installations requiring more robust weather sealing and a significantly higher transmission range.
Within the repository of smart mailbox sensors, this unit represents an entry-level cloud-dependent notification device.
