Nuki Smart Lock Pro vs TP-Link Tapo DL100

TP-Link Tapo DL100 for value and completeness: keypad, one-time codes, anti-peep entry, doorbell button, IP54 protection, ten month AA battery life and hub-free Wi-Fi. Nuki Smart Lock Pro wins on integrations, including Apple HomeKit and Matter, and on retrofit installation over an existing cylinder.

Nuki Smart Lock Pro retrofits European cylinders, requiring a protruding cylinder with a key operable from both sides, and it is not made for US deadbolts. TP-Link Tapo DL100 replaces a standard deadbolt and fits 54 mm and 38 mm bores without extra drilling.

No. Nuki Smart Lock Pro includes Wi-Fi, so remote access works without the paid add-on the cheaper Nuki Go requires. TP-Link Tapo DL100 also has built-in Wi-Fi and Bluetooth, with no hub and no subscription for its app, alerts and activity log.

TP-Link Tapo DL100 has a backlit keypad with up to 200 codes plus two mechanical backup keys. Nuki Smart Lock Pro relies on your existing physical key unless you buy the Nuki keypad or Keypad 2 accessory for codes and fingerprint entry.

TP-Link Tapo DL100, rated IP54 on the exterior assembly for a sheltered doorway. Nuki Smart Lock Pro carries no weather resistance rating, although as an interior retrofit it sits on the inside face of the door, where exposure is less of an issue.

Owners of European cylinder doors who want a premium retrofit with built-in Wi-Fi, a rechargeable battery, hands-free auto-unlock and full Matter and Apple HomeKit support, and who will add the keypad accessory if needed. For a self-contained keypad deadbolt, TP-Link Tapo DL100 costs far less.
