NUKISmart Lock Pro (4th generation), smart door lock with Wi-Fi and Matter for remote access, electronic door lock turns your smartphone into a key, with Power Pack, for Euro Profile Cylinder, white

➕ Futureproofed with Thread➕ A wealth of smart home integration options, Matter, MQTT, Alexa/Google➕ Highly configurable➕ Fairly easy to set up (if you don't need an adapter)➖ Accessories (door sensor, keypad/fingerprint, fobs) are expensive➖ Bulky compared to some smart locks➖ Locking knob adapters not included/free when purchasing from AmazonFirstly, I want to say how much I appreciate the company's ethos with this smart lock. They have fully embraced the smart home community by implementing requested features such as Matter/Thread and MQTT. I really, really wish all smart device manufacturers were like this.On setting up, I found that I needed an adapter for my internal locking knob, and these vary by lock manufacturer. If you purchase from the Nuki site, you'll learn this as you go through the buying process. On Amazon, you might not find out until it arrives. I think the adapters _are_ sold on Amazon, it would be nice to see them discounted to free if purchased at the same time. I ordered a free adapter from the Nuki site, but it still hasn't come. Luckily, I own a 3D printer and there are STL files available around the net, so I was able to make my own.It's important to note that THIS DOES NOT COMPLETELY REPLACE YOUR KEY. Your key is now the last resort option to enter your house. The person who left the one star review after having to call a locksmith made a grave error, either by ignoring the advice that the lock needs to have an emergency mode (keys can go in both sides at the same time), or by thinking they no longer needed to carry their house key. These are electronic devices: some will fail, the lock battery might die, your phone battery might die, sometimes they might get into an unexpected state. If you leave your house without a backup means of entry, you only have yourself to blame when things go wrong.The lock is highly configurable via the app. You can set it up to auto lock, you can also have it auto unlock when you approach it, and you can tweak the options for those to suit. I'm still fine-tuning mine. You can set up night mode, schedules, Lock 'n' Go (unlocks the door and then locks it again quickly afterwards).The accessories are quite expensive. The door sensor is only compatible with the lock (no Matter/Thread support) and is more than twice the price of the Aqara P2 Matter/Thread door sensor. The keypad is twice the price of a Simpled keypad. If you're running Home Assistant, it might be worth looking into alternatives unless you want to lock yourself in (no pun intended) to Nuki.

I got the Nuki Smart Lock pro 3.0 and installed it with relative ease. At first, I had a struggle with the lock not turning the key, but later I found that my key handle was not long enough. After I used a longer key handle, it worked immediately. The support I got from nuki was superb. The turn around time from the support team was less than a day via email considered that I am a US Customer.Compared to its main competitor, Yale, it was a direct opposite. I made a wrong decision to purchase the Linus lock and wasted few months because the Yale pre sales supports in the US and UK were so disoriented and did not know that the home app only works in Europe. I found it out in the hard way right after I installed the Linus lock and I had to return the locks and all the accessories.Nuki is different. The support team before and after sales are both efficient. They have full knowledge of the product and extremely helpful in resolving issues reported by me. The HW and SW are excellent and flawless. Great product! I highly recommended this lock especially for the US customers who use euro cylinder lcocks.

Tonight, my second Nuki lock has failed. I use the Nuki cylinder too, which in itself is fine but pointless without the lock.I knew this was going to fail as it started acting like my first one. I've only had this one since July so it hasn't lasted long (it's October as I write this). The last one lasted longer, but still cheap, must be cheap parts because I've heard the motor struggling over the last few days and tonight it won't do anything.It's a shame - the functionality and features are brilliant, but I've got no choice but to look for an alternative.Avoid.

Pretty decent bit of smart tech. Initially it was a pain as I couldn't use it with my lock. The thumb turn wouldn't come off on that one so I had to order another. Once that arrived I realised I needed an adapter, it doesn't actually state that on the Amazon site, so that was a surprise.Once I got the adapter I got it set up in no time. It's doing quite well, it has struggled once or twice, but seems to be doing better now.They should have designed these to have a recess that accepts either a thumb turn or an adapter for a key. My thumb turn almost fitted, it would have saved me buying a new lock and adaptor if it had been just 1 or 2mm wider.Other than that, great addition to the smart home

Had always been reluctant to get a smart lock, but after a lot of research this fit the bill nicely. Set up up was easy, less than 10 minutes start to finish. Great thing is that it can be still used as a standard lock and being internally installed no-one is any the wiser, so doesn't scream teck head lives here making to a potential burglary target.Like the auto lock feature and smart unlock when you get home. Is it perfect, not quite, would be nice to be able to set it to lock using a single turn while at home then automatically add a second turn when it switches to night mode, but not a deal breaker and it's a pity that you need the magnetic sensor (sold separately) to enable extra features such as not automatically locking if door isn't closed, but again not a deal breaker. It's not the quietest but at least you know your door is locked behind you.On the plus side you do get built in WiFi, rechargeable battery unit and Matter included with the pro version.So in conclusion if you are in the market for a smart lock, but don't want to shout out that you have one, get one!
