Nuki Smart Lock 3.0 Pro - on existing lock
vs
full mechanism
Can you share your experience comparing both?
I am also curious about EMI (electromagnetic interference). I assume full lock mechanizm is easier to open, because electronic it is "closer" to outdoor side. Unless they have some magic protection with new models, but I doubt. Do you know anything about that?
Which one would you buy and why?
PS consider winter and summer
open cradle
full smart lock will often have a way for emergency power to be applied if batteries are out. yale has contact points for a 9v battery, others have usb-c for a power bank.
as far as i could see in a yale they had the design right. the outside unit had keypad and rfid reader but the logic was inside. i have seen cheap ones where all the electronics were in the outside unit with the motor inside. use a hammer to knock off the outside housing and apply power directly to the motor opening the lock...
this was a few years ago, and yale was ha unfriendly. their zigbee adapter used proprietary encryption so you needed their hub and their cloud service. no local control. i don't know if that has changed
heimdal.com have a lock where they list explicitly which features require their app. they seem to be very ha friendly.
the bolt on ones of course have all bits on the inside. some can also have a wireless panel outside. no way to apply emergency power from outside. and you must check how much your lock needs to be turned to lock/unlock. not all bolt on smartlocks can handle locks where there is a large movement needed end to end.

(adapter to existing lock)
this is my concern
not exactly this products
I feel "safer" with adapter to existing lock, but maybe it is way better, than I think
I am worried about device which make electronic interference which can unlock many door without physical contact.
Besides of that I am worried about reliability. Standard lock always work with a key.
I see. Bolt smart lock has interesting logic.
but if it discharge, then I will not get inside right?
open cradle
the one like the last link you sent can not be charged from the outside. but you can of course use the key. that you left at home since you never use it...
so with that kind, have a key outside the apartment that you can get to in an emergency
boreal light
what about electronic interference with special device to "hack" them for all this devices?
I forgot proffesional name... was it just EMI or something else?
Do you know what I am talking about?
open cradle
zigbee is encrypted
boreal light
ok I will find what I am talking about, encryption will not help here
ah it is more called EMP method
open cradle
so if they use zigbee and local control they should be safe. if your ha server is up of course
a few wifi based locks in the past have used unencryped protocols to their cloud aervice and been very easy to hack
boreal light
give me few minutes. Of course I can't find good example when I need 🙂
with very simple lock, but it work with "everything" what is electrical
just can't find good example right now
this is serious threat for all electrical security devices
encryption will not help here
open cradle
i can't see how emp would open a lock. kill it - sure. but not unlock it
boreal light
why? the idea is the same
the only way to be safe from this is to keep the "brain" deciding to open far away from door
which is not the case for any of this smart lock installed in door
open cradle
unlocking a door bolt involves getting the motor to unlock it. an emp pulse probably won't do that
boreal light
sure it will
open cradle
it will just kill the brain
boreal light
if smart lock get an impulse to open a door, then it will turn the lock
safe etc. are vulrnable to it, many locks are
I wish someone show tests for smart locks
I would say the question is which products are safe and which not. Unfortunatelly nobody write in description "EMP safe" smart lock.
open cradle
the emp could potentially reset it to factory defaults. not open it
boreal light
hmm interesting I can't find videos in YT about that. Some time ago I saw at least a few showing custom made EMP.
boreal light
the emp could potentially reset it to factory defaults. not open it
why so sure?
open cradle
e.g. for a yale i think you then need the master rfid chip that came with the lock to set it up
boreal light
in many cases the rotator mechanism is about getting let's say 12V impulse on some wire to active it
so it will happen with EMP
this is not so strong EMP to burn everything, just reasonably strong to mess with device
which is probably called EMI
I am not english native speaker
open cradle
and what it will do is crash and reboot the device
boreal light
and what it will do is crash and reboot the device
I guess we need video proving it. Without that we can't know.
open cradle
it would be extremely random to have it actually unlock

ok let's back to main topic:
Do you recommend some locks over another?
like bold smart lock
will finger print locks work in winter and summer without any issue?
*finger scan
open cradle
finger print in winter can be difficult so you shoyld be able to unlock from phone
i do not have experience with smartlocks except looking at a yale roorman where the main electronics were on the inside and there was a lot of metal between outside and electronics
