Performance metrics for the Evernary Smart Mailbox Alert demonstrate a two-stage communication link utilizing either 433MHz or 915MHz RF between the sensor and an indoor bridge. This frequency selection allows for effective signal penetration through thick metal mailbox walls. The indoor hub connects via 2.4GHz Wi-Fi, though standardized testing shows that it lacks support for 5GHz SSID steering, which may necessitate specific router configurations during the initial handshake.
The sensor housing provides IP65-rated ingress protection, although the mechanical contact points are subject to oxidation in high-humidity environments over time.
Standardized operational data suggests a battery cycle of 6 to 9 months. The system utilizes the Tuya/SmartLife firmware backend for remote notification management. Technical analysis suggests that the indoor hub should be situated in a location with clear line-of-sight to the mailbox to minimize signal desensitization from household electronic interference.
- Functional feature highlights: Mechanical Tilt Sensing, Local Audible Alert, Push Notification.
For users who prefer a sensor utilizing a 900MHz spectrum for even greater interference rejection, the Ring Mailbox Sensor offers a distinct architectural approach using LoRa technology.
As part of the smart mailbox sensors category, this unit functions as a specialized gateway for perimeter signal relay.
