The interesting question is what happens when the battery dies · review
Nuki's fifth-generation lock puts Wi-Fi inside the unit, so remote access needs no bridge or hub, and adds Matter alongside Bluetooth. The battery charges at the door with the supplied cable rather than coming off it.
The bottom line The top of this hub, and the one most likely to still be supported in five years. The absence of a bridge is what you are paying for.
Everything in this hub is a retrofit that turns your existing thumbturn. What separates them is not what they do on the door — it is what they need around it, and how long the company behind them keeps them working.
Earlier Nuki locks, and most competitors, need a small bridge plugged in near the door to reach the internet. It is another device, another socket, another firmware, and the commonest thing to go wrong in the system. The fifth generation puts Wi-Fi inside the lock and deletes the whole category of problem.
Which means it is not tied to Nuki’s own app for basic operation, and it will join Apple Home, Google Home or Alexa directly. On a device with a ten-year life on a front door, an open protocol is a hedge worth having.
The battery is charged in place with the supplied cable, in about two hours, rather than the lock coming off the door. Nuki states months per charge and does not publish the daily cycle count behind it, so that is reported as a claim rather than converted into a number of weeks.
Make the door harder to force. It turns your thumbturn. If the door itself is the weak point, the money belongs in a cylinder and a strike plate, not here.
Someone who wants the lock to work remotely with nothing else plugged in, and who intends to keep it for a long time.

Because the alternative is a bridge: another device, in another socket, near the door, that has to stay powered and updated. Every bridge is a point of failure and a thing to explain to whoever else lives there. Putting the radio inside the lock removes it.
It costs more than Bluetooth, which is why Nuki designed the battery to be charged at the door in about two hours rather than removed. Nuki states months per charge without publishing the cycle count behind it, so we report the claim rather than a converted figure.
For the update record, often yes. A smart lock is a device you live with for years, and the difference between a company that still ships firmware in 2030 and one that does not is invisible at purchase and decisive later. Nuki is the most established name in this family.
