I use this app and Smart Lock for my business and it's great. It's user friendly to set up and I can schedule it to lock and unlock my door. The door sensor (in beta) is quite reliable. It would be nice to have a door closer option so that I only get one notification per entry. But I realize for most people that is not a problem. The only reason I gave it 4 instead of 5 stars is because the notifications can be inconsistent but that may be due to my phone (OnePlus Nord). Highly recommended!

The app never rings when the door is unlocked... Never! Battery optimization is off, and still nothing. I have the bridge, but it's useless if I can't hear the doorbell ring. I had a Pixel 6 Pro and had the issue and now with my Pixel 8 Pro... same thing.. even if the app is open, it doesn't ring. And when I run the diagnostics, it shows everything is connected.

Great app. I had a problem that I couldn't invite a new user unless I was standing within Bluetooth distance of the lock. The Nuki support team described how I could solve that. I really appreciate how Nuki keeps improving the app over time.

Thank you for your feedback! Remote user invitations work if your Smart Lock is connected via a Bridge or a device with Remote Access. If it doesn’t work for you, feel free to reach out via the “Help” section in your Nuki app – we’re happy to assist!
