Overview
The eufy Security Smart Lock C220 (model T8506) is a wifi fingerprint deadbolt with six ways to unlock, including Apple Watch and voice assistants, built on eight AA batteries and certified BHMA Grade 3 after 100,000 lock and unlock cycles.
- Six unlock methods including fingerprint, Apple Watch, and voice
- BHMA Grade 3 certified after 100,000 lock and unlock cycles
- Self-learning fingerprint sensor improves with repeated use
- Built-in wifi, no separate bridge required
Who it's for
Suits households that want to hand out temporary passcodes to cleaners or pet sitters and, especially, anyone already running eufy doorbell hardware who wants the two tied into one app. Owners in consistently wet or humid climates should weigh the IP53 rating and the moisture complaints below before installing it on an exposed door.
Pros and cons
- Install reported at 15 to 30 minutes with no drilling
- App keeps an entry log and issues temporary codes for cleaners or guests
- Fingerprint accuracy improves with repeated use for most owners
Performance notes
The fingerprint sensor is built to refine its match with each touch, so accuracy for a given finger is expected to climb over the first weeks of use rather than staying static. Auto-lock runs off a timer counting from the last unlock, and the lock can also fire an alarm if it detects an unusual attempt to open it. Eight AA batteries are rated for around 8 months, closer to 9 months in at least one review, with wifi signal strength to the router affecting the drain.
