Enable NUKI to be used with Anti-Panic-locks in combination with door magnet

Product name

Nuki Smartlock in combination with door magnet


In cases where Nuki is installed with a lock with anti-panic-functionality, Nuki looses calibration whenever the door is opened by pressing the handle from the inside without turning the lock. The smartlock will think that the lock is still “locked” even though it is unlocked.

In case there is a doormagnet Nuki may easily know that it is not locked anymore. In terms of IFTTT be something like: If lockState is locked and doorState chages from door closed to door opened, then lockState is changed to unlocked.

After that, it would be possible to close and lock the Nuki again.


Nuki will either automatically recalibrate or at least automatically change lockStates to correct stat.


There are cases where a lock with anti-panic functionality is required and thus given. Also in these cases it may be useful to have a smartlock to open the door from the outside. Nuki will lose its calibration in these cases and will not function until it has manually been calibrated.

There is a hidden feature in the latest Smart Lock 3.0 (Pro) firmware, which you might want to give a try:

If the Smart Lock 3.0 (Pro) runs a firmware >3.6.9 and debug mode of the Smart Lock is active and a door sensor is paired the Smart Lock goes in state “Undefined” when the door is opened while the Smart Lock thinks it is locked (i.e. the door was opened through a panic function or with a key when a cylinder with priority function is used, where the inner and outer keys are not rotating together).
In state “Undefined” it is still possible to lock / unlock / unlatch the door. Performing a lock command will drive the lock to full locked position in order to recalibrate the internal position sensing of the Smart Lock. In case of an unlatch command, the Smart Lock immediately unlatches the door and repositions itself based on the unlatched position. Unlock commands via BLE and remote unlock commands sent through the specific error dialogue that appears in “Undefined state” within the Nuki App, trigger an unlatch door command. All other unlock commands are denied.
After any of the above lock commands is finished the Smart Lock exits the “Undefined” state and displays the correct state again.
