eufy Smart Lock E30
Cheap built-in Wi-Fi and fingerprint, undermined by a Grade 3 body and shaky Matter.
Overall score 6.7/10
Pros
- + Wi-Fi is genuinely in the lock — you are not buying a bridge afterwards, unlike most of eufy's older C-series
- + Both fallbacks covered: a keyed cylinder and a USB-C emergency contact
- + Fingerprints are held on the device, not uploaded, and eufy charges no subscription for lock features
- + Eight months on AA cells with no proprietary battery pack to source later
Cons
- − ANSI/BHMA Grade 3 — the weakest residential grade, and a real step down from the Grade 1 locks at $250-$350 here
- − The Matter support on the box did not work in PCWorld's testing across two different Thread hubs; treat it as unproven rather than a feature
- − No Apple Home Key, so iPhone users get app control but not tap-to-unlock
- − The fingerprint reader is the least reliable of the biometric locks in this set
eufy Smart Lock E30 review: what the specs say
Cheap built-in Wi-Fi and fingerprint, undermined by a Grade 3 body and shaky Matter. At $169.99, eufy's 2024 model sits among the cheapest we cover — the smart Locks we compare run from $79.98 to $399. It scores 6.7/10 overall, calculated from published specifications across 8 categories rather than from a subjective impression.
Its strongest showing is Fail-Safe Access at 8.5/10 — what happens when the battery dies, the Wi-Fi drops or the app is down — physical key, emergency power contact and offline codes. The spec buyers most often discover too late. The weakest is Security at 4.0/10, which is the trade-off to weigh before buying: if that is the specification you care about most, one of the alternatives below will serve you better.
Worth knowing before you buy: ANSI/BHMA Grade 3 — the weakest residential grade, and a real step down from the Grade 1 locks at $250-$350 here; and the Matter support on the box did not work in PCWorld's testing across two different Thread hubs; treat it as unproven rather than a feature. Every specification on this page comes from eufy's own documentation or a verified retail listing — where a figure is not published, the table says so rather than estimating it.
