It draws the stronger owner reception, carries IP54 sealing for a sheltered opening, and includes 2.4 GHz Wi-Fi, Bluetooth, a doorbell button, anti-peep codes, one-time codes and a physical key, with Alexa, Google and SmartThings and without Apple Home or Matter. The Nuki Smart Lock Go is the indoor euro-cylinder retrofit, with Matter over Thread and the wider platform list, Bluetooth unlock and geolocation, while passcode and fingerprint need accessories and remote access is a one-time purchase. The two do not mount the same way. Pick the TP-Link Tapo DL100 to replace a sheltered deadbolt. Pick the Nuki Smart Lock Go to leave a European cylinder in place.

What the differences mean

How it attaches

The Nuki Smart Lock Go mounts inside, over a European cylinder, and you keep that key. The TP-Link Tapo DL100 replaces a deadbolt on a 54 mm or 38 mm bore. A rental with a euro cylinder is a Go problem. A house with a standard US deadbolt under a porch is a Tapo problem. Crossing them means returning one.

Keypad features

The TP-Link Tapo DL100 has the keypad built in, with anti-peep entry, one-time codes, a doorbell button and a lockout after repeated failures. The Nuki Smart Lock Go can add a passcode only with a keypad accessory, lists one-time and periodic codes the same way, and marks anti-peep and a doorbell as not supported. Fingerprint on the Go is another accessory. The Tapo has no fingerprint reader at all.

Weather

The TP-Link Tapo DL100 is IP54. Its write-up still says that is a sheltered doorway, not a wall in the rain, because water can reach the key cylinder. The Nuki Smart Lock Go is not weather rated and is described as an indoor retrofit. Sheltered US door: Tapo. Indoor euro cylinder: Go. Fully open weather is a weak case for both.

Platforms

The Nuki Smart Lock Go supports Apple Home, Google, Alexa, SmartThings, Home Assistant and Matter over Thread, with 2.4 GHz Wi-Fi and Bluetooth. Remote unlock is a one-time purchase. The TP-Link Tapo DL100 supports Alexa, Google and SmartThings on its own Wi-Fi and Bluetooth, and it marks Apple Home and Matter as not supported. Home Assistant on the Tapo is not documented. Battery life on the Go is not documented. The Tapo is rated about 10 months on 4 AA cells.

What owners say

Owners are not arguing about the same hole in the door. Nuki Smart Lock Go owners like that nothing is drilled and that the lock meets them at the threshold with their hands full. The repeated worries are a motor that fails inside a year, cells that swell, and remote control that costs an extra purchase. TP-Link Tapo DL100 owners single out a timer that locks the house after the door closes, codes they hand to guests, and an install measured in minutes. They are the group that talks about water reaching the key cylinder on a fully exposed mount, and about notifications that sometimes do not arrive. Apple Home never comes up as a Tapo win, because it is not on the lock.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
