Hello, I'm replying about my door lock. I didn't have any problems opening or closing it. I think you should recalibrate the opening and closing of the door via the app. I've set it to single close during the day and double close at 9pm. Maybe the mechanical part of the lock is stuck and not running properly in the tracks. I hope I was able to help you, ciao!

Depends on your door. I had to make one using my 3d printer since the adapter included in the box did not fit.

Dear GaRoMeSi For your safety, the Nuki relies on a panic lock. In other words, a key that can be turned on the inside and outside, or, as you have already written, a knob on the inside. This is the better option anyway. The knob is unscrewed and fitted with an adapter, which is then inserted into the head of the Nuki. The version with the key also works, but it can happen that the key slips out a little bit when it is in a horizontal position. From the outside, you can connect the power to the mounted Nuki with a USB C cable directly to the battery. This prevents it from being empty when it arrives in the flat. Otherwise, the battery lasts approx. 10 hours after charging. 3 to 5 months. The Nuki 3.0 Pro has a little more power consumption with its built-in WLAN module. But if you can operate the lock with the key outside, because there is a knob inside with the Nuki, you can open the lock analogue and then plug the power back in. have fun with it, it's a pleasure greetings Reto

In the description of the product with EU cylinder I see "........1 Adapter for Dormakaba/Kaba (yellow) included in delivery. Other adapters can be ordered separately" Since the CH cylinder is presumably a Dormakaba/Kaba, the yellow adapter can be securely placed on the axis of the rotary knob and the Smart Lock can be used in this way.

yep. just dismantle the knob, measure it and order the right adapter. costs chf 2.00
