I have a Magnum security door from HT doors with a handle on the inside and a bow tie instead of a key. I have a non-rotating sphere on the outside. The condition for each el. the lock is a lock with an insert, so that it can be locked even if there is a key or a fixed mechanism with a bow tie on the other side. Without this, there is no point in considering any el. of the castle. I got it primarily to keep my kids from losing their security door keys outside. I primarily wanted a fingerprint + pin input (as a backup). This can also be opened with an NFC key fob, HomeKey, or mobile phone from the app. Installation is quite simple. There is also a video tutorial in the app. The easiest is with the key on the inside - it can turn the key head directly without an additional adapter. If you don't have a key but a bow tie like me, watch out. not compatible with Magnum doors. one adapter fits there by circumference (almost - I pressed it in a bit with a hammer), but the hole for screwing in the side screw (worm) doesn't fit anymore. Anyway, after pressing it held up great for about 1 week. then it loosened and it was a problem to open from the inside because the adapter on the shaft was turning - the round profile of the shaft on the door side was not a good idea. I had to dismantle it (a matter of one minute, but my wife probably wouldn't have known what to do). No other adapter is holding the circuit there, so I glued it there and so far it is holding - I have no other option. After unpacking it is a bit confusing what software to actually install. the text was about one SW, the QR code referred to the second SW and below the QR code was a description of the 3rd SW. I installed the original Aquara Home app. I must say that the SW is sophisticated. Only the English is machine - about 97% of the text is OK, but it can be a bit confusing in a few places, but nothing a layman can't handle. The important thing is that Aqara Home addresses what other users have criticized here. possibility to set the lock/door with an external non-rotating ball (maybe they used a different SW. ). After calibrating one and the other position (for unlocking and locking) you can click on "Hold latch" (meaning the firing pin) + the selected time (I give the shortest 1 second). After the bolt is captured, the motor continues past the calibrated position to engage the missile and the safety door is unlocked and bounces. After a second, the gun comes back out (calibrated motorcycle position) and I can slam it shut behind me normally as if I had opened the door with a key. I haven't had a problem with it yet. Locking can be done in 3 ways. By default, it is locked only manually - that is, by pressing a button on the keypad or by turning the mechanism. It can be set to auto-lock with a slam - that's what I use. When you slam the door, it locks. This only works based on impact (accelerometer). So if you hit the door when it's open, it locks. Then there is another similar possibility. locking after a certain period of time. When I slam the door (again, accelerometer detection), it locks after a defined time if the door has not been tampered with. I don't use it yet, but I'm thinking about it, because sometimes it happens that I go back and forth and some delay of say 5-10 minutes would be useful. But this way I know it's always locked. I slam and hear the lock The only thing I'm afraid of is that there could be a situation where it starts locking just before closing, then the bolt would hit the door and that would be unpleasant. But so far it hasn't happened. The auto-lock function is labelled "Lab" in the app, so it's a test function. If it is closed very carefully, it may not register the impact and lock. Then you need to press the lock on the keypad, or turn the mechanism inside. The rotation of the mechanism can be supported by a motor - recommended. Turning is not as comfortable as with the original bow tie or key. After activating the function, just turn the mechanism and it will turn as it should (there is only a delay of about a second). You don't address whether you have the right position. 2 speeds can be defined. when I turn slowly, the motor turns in slow/quiet mode. If I turn faster, it turns fast. Each mode (fast and silent) has a choice of 3 speeds (6 speeds in total). You can also set only one speed. On the speed of rotation. the fastest rotation is quite noisy. I wouldn't want to open like that in the morning or evening. And the slower modes are sometimes a nuisance. Therefore, you can set the time interval when it closes/opens. During the day I have a medium speed - I put my finger on it and it opens about the same as if I were turning a key. The fast mode is faster, but probably useless for me. At night and in the morning, I'm on silent mode. which is significantly quieter, but also significantly slower. I put my finger on it and wait about 8 seconds. If I tried to open the key quietly, it would also take me longer than normal. not 8 seconds, but again, it's quiet and comfortable. The external keypad looks nice on the door. I have a silver version on a darker door with imitation wood. The lock is quite large inside, but with the cover where the wood imitation is, it +- matches the door and I don't notice it as much as with the silver cover. The external keypad just sticks to the door via an adapter so you can take it off and change the batteries. The adapter has a magnet and the keypad has a hall sensor and when disconnected it will start beeping (stops with fingerprint, pin, card, phone). When you enter a wrong pin, card, or fingerprint it first rejects at normal volume, then louder with a different sound, and finally it starts blaring like an alarm. The volume can be adjusted and the time when the alarm can sound can be set. But I've had it active all day. When entering a pin, you can enter a random number, then the correct pin and continue with random numbers. and if there is a correct pin between the digits, it will unlock - this is to prevent someone from easily learning the correct pin. If you run out of batteries, you can open it normally with a key or by turning the mechanism, only the adapter has to hold: -). The keyboard is powered by 4x AAA. The bike comes with a lithium battery with USB-C connector and then a pencil battery holder that fits in place of the lithium battery, which is quite handy. you take out the original battery, put it aside to charge, and leave the adapter with the pencil batteries as a backup solution. or it comes with a cloth bag for the power bank, which can be hung by the handle and charge the battery when plugged in (you just need to leave the cover off). For remote or automated operation and control of the lock you need to have Aqara HUB M3 or newer (newer is not available yet). I don't have it, so I can't judge. But I can create a temporary pin. this can only be entered once. I normally connect to the lock via Bluetooth on my phone, but if I want to set something on the keypad (many settings are common), I need to manually wake up the keypad (by pressing any button) and then both are visible in the app. in addition to the settings, I also check the batteries, which I haven't charged yet. I've only had it running for less than a month. the keypad reports 100% and the lock 84%. Our lock does about 5-10 cycles a day. While I consider the lock to be secure, the lock is not for better security, but for easier opening. It's another opening. And I confess that I haven't quite figured out how the insurance company's view of theft claims is. Electronic locks, like mechanical locks, must meet safety standards and safety classes. These vary greatly by state and I assume this is not addressed by Aqara. But if you insured the house/apartment without information about the security doors (or the security class of the lock), it probably doesn't matter.
