The eufy Smart Lock E31 is a Good Deal, offering multi-method unlocking (fingerprint, keypad, app) and broad smart-home compatibility at a mid-range price. The feature set aligns with typical mid-range expectations for convenience and connectivity, while explicit ANSI/BHMA Grade 1 certification and detailed door compatibility are not stated.
When selecting deadbolts, focus on security rating, lock type and control, and compatibility and dimensions. Here is how this product performs:
1.
Security Rating (fingerprint access; keyless entry; remote unlock) : At this mid-range price, buyers typically expect Grade 2 or explicit cycle testing. The listing does not state a BHMA/ANSI Grade 1 or 2, so the security claim is typical rather than standout for premium hardware. Confirm certification if maximum physical security is a priority.
2.
Lock Type & Control (smart deadbolt; keypad access; app control) : This matches mid-range benchmarks: multi-method unlocking and built-in app/voice control are typical for this band. Fingerprint plus keypad is a stronger-than-basic offering and aligns with common mid-range feature sets.
3.
Compatibility & Dimensions (HomeKit support; Matter support; Alexa compatibility) : Connectivity and Matter/HomeKit support are toward the higher end of mid-range compatibility. However, door compatibility details are not specified; mid-range locks often list bore/backset and thickness explicitly, so buyers should double-check fit for their door.
Deal price at $144.99: sits near the upper end of the mid-range band for deadbolts. The price is consistent with mid-range smart locks that add fingerprint and built-in app control; no price history is provided to compare recent averages.
Overall, this Good Deal fits buyers who want a modern smart deadbolt with fingerprint entry and Matter/HomeKit support without moving into premium pricing. Great for households wanting app and voice control; double-check the lock's ANSI/BHMA grade and exact door prep/backset compatibility on the product page and confirm warranty terms before purchase.
