Eufy Smart Lock C220 vs Nuki Smart Lock Pro

The Nuki Smart Lock Pro wins overall for smart-home users, with built-in Wi-Fi, support for Apple HomeKit, Google Home, Alexa, SmartThings, Home Assistant and Matter, hands-free auto-unlock and a 2-year warranty. The Eufy Smart Lock C220 is the better value for a US deadbolt, offering built-in fingerprint entry, anti-peep passcodes, IP53 weather resistance and longer AA battery life at a lower price.

The Nuki Smart Lock Pro is a retrofit for European euro-cylinder doors with the widest platform support, but keypad and fingerprint entry are separate accessories. The Eufy Smart Lock C220 is a full US-style deadbolt with a built-in fingerprint reader, keypad and physical key, though it only works with Google Home, Alexa and Home Assistant.

No. Unlike the cheaper Nuki Go, the Nuki Smart Lock Pro has Wi-Fi built in, so remote control and smart-home integration work out of the box. The Eufy Smart Lock C220 also includes built-in Wi-Fi for remote access, so neither lock needs a separate bridge for that.

The Eufy Smart Lock C220 does, rated around 8 months on 8 replaceable AA batteries. The Nuki Smart Lock Pro uses a rechargeable built-in battery rated around 6 months per charge, which owners can top up over time rather than replacing cells.

Buy the Eufy Smart Lock C220 if you have a standard US deadbolt and want built-in fingerprint entry, anti-peep codes and IP53 weather resistance at a lower price, without paying extra for a keypad. The Nuki Smart Lock Pro is the choice for European doors and buyers who want Apple HomeKit, Matter and the broadest integrations.
