Frequently Asked Questions
Which is better overall, the TP-Link Tapo DL100 or the Nuki Smart Lock Ultra?
TP-Link Tapo DL100 on value and completeness: keypad with up to 200 codes, one-time codes, anti-peep entry, a doorbell button, IP54 protection and ten months of AA battery life. Nuki Smart Lock Ultra wins on integrations, adding Apple HomeKit and Matter over Thread, and on retrofit installation.
Which doors do they suit?
Nuki Smart Lock Ultra retrofits over a European cylinder, keeping your existing key, and its guided install adapts to UK, US and EU door thicknesses. TP-Link Tapo DL100 replaces a standard deadbolt and fits 54 mm and 38 mm lock bores without extra drilling.
How do you unlock each one?
TP-Link Tapo DL100 offers a backlit keypad, Bluetooth, the app and two mechanical keys. Nuki Smart Lock Ultra unlocks from the app, by Bluetooth, hands-free on approach with geolocation, or with your existing key, and it needs a Nuki keypad accessory for codes or fingerprint.
Do either need a subscription or add-on?
No. Nuki Smart Lock Ultra includes Wi-Fi and Matter, so remote access works without the paid add-on the cheaper Nuki Go needs. TP-Link Tapo DL100 also works remotely over its own Wi-Fi with no hub, no bridge and no subscription.
Which works with Apple Home?
Only Nuki Smart Lock Ultra, through Matter over Thread with an easy Apple Home QR setup, plus Google, Alexa, SmartThings and Home Assistant. TP-Link Tapo DL100 covers Alexa, Google Home and SmartThings with PIN verification, and has no Apple HomeKit or Matter.
Who should buy the Nuki Smart Lock Ultra?
Owners of European cylinder doors who want Nuki's fastest and most compact lock, built-in Wi-Fi and Matter with no add-ons, hands-free unlocking and a 2 year warranty. For a self-contained keypad deadbolt on a US-style door, TP-Link Tapo DL100 is far cheaper and better equipped.
