Eneloops would only last about 3 weeks. And disposable last 2 months. This door is used a lot and since it has Zwave and a door open sensor it sends info on every open.

Bonus, since it can handle the lipo AA batteries that put out 1.8v and it gives the motor more oomph I made the battery pack give 7.2v and it never sticks anymore.

This is a garage-door so its not critical access but is used a lot.

    Imagine being locked out of your house because you forgot to bring keys with you.

    Like, I'm sorry if you disagree with this, but holy shit, having electric locks on your doors where you can get into your house based off a fingerprint or a code is a fucking game changer.

    I have two on my doors, one on the front, one on the back, and I installed them at a week or two apart, so if one of them starts complaining that the battery is low, the other one's still good. If one of them goes dead while I'm on vacation, the other one's good.

    Not to mention that you can unlock the door from your phone in case somebody comes over unexpectedly, or if you have a friend coming in from out of town and you're going to be at work when they arrive, you can create a code for them to unlock your front door and come in while you're not even there.

    Plus they still have key locks that I can use if the batteries are completely dead and they can be powered by a 9 volt battery in case I don't have the key with me.

    They're freaking awesome and I am glad they exist.

    Yeah and it makes it pathetically easy to break into your house. Just search online for some of these “security locks using fingerprints”. Its even easier to break into sometimes than a regular shitty lock.

    I can head out for a walk without bringing my keys with me. Kids can open the door while I’m grabbing the groceries or other stuff. Can provide a temporary code for someone to check on it while I’m out. Family can have a code for emergencies, or if they need to watch the kids.

    It’s hella convenient actually.

    Wait until you hear about this neat invention called a "key". They are quite wonderful, they can securely lock and unlock your door in any conditions and don't need those pesky batteries.

    Wait until you hear about this neat invention called a "smart lock". It uses this marvelous key invention you kindly detailed but it also uses magic powered rocks that can send small vibrations in the air to communicate with other magic rocks at home. If their magic energy source is depleted the object you refer to as a "key" may also be operated on this mystical lock to which the lock then whispers: "just let people enjoy things".

    the batteries in mine last a year and I don't have to carry around any keys but my car keys (when I take the car).

    definitely worth it. I can leave the house with nothing but my phone or bank card and run errands etc. people can access my house when I want them to without issue. it's a huge QoL improvement for me

    that said, I'd still prefer an electronic lock that had a key as well, and wasn't a touchscreen

    Well done, and I’m surprised at all the technophobes in a 3d printing community.

    I mean, there has always been a correlation between being technical (as in profession/skills) and being paranoid about technology. When you are in the field, you get a window into how ignorant most of the tech products are security-wise for example. And I guess a good portion of 3d printing people - especially the ones on lemmy - are technical (as in profession/skills), not/not only tech lovers.

    Considering a lock is pickable in a few seconds, what’s the security risk? A lot of these locks even dont have keys, so you’re removing a very easy and common vulnerability.

    When you are in the field, you get a window into how ignorant most of the tech products are security-wise for example

    Most people just don’t actually think for themselves is the issue. Regular deadbolts aren’t secure themselves already.

    Also, if the door is locked, they just break a window or kick a door in. A deadbolt isn’t a good way to secure you house regardless, you need reinforced doors and frames too. So without all these extras, what risk is an electronic deadbolt above a regular one?

    Can’t have your keys stolen and your house just walked in either, so that’s MULTIPLE security avenues fixed with an electronic lock.

    And very few people are going to be capable of hacking these compared to older and easier methods as well.

    Hey I haven't used this model specifically but a PSA to anyone with a motorized lock:

    If your battery is dying seemingly too fast (and it's not an old battery), your deadbolt is probably misaligned. The friction takes a huge toll on the motor and battery life. They should last MONTHS at minimum.

    I am confused, is this not possible to wire properly to a power supply? even though this has increased capacity it would still always be in the back of my head that my door might run out of power 🤔

    This did make me realize I've never seen a deadbolt reversed. As in the door having just a metal framed hole, and the bolt come out of the frame. Seems like the easiest way you would be able to run power to it. (Maybe not the most structurally sound, probably depends on the door material)

    I don't know. I think that if you built the receptacle right, It could probably work pretty well... Most deadbolts are pretty shit in general (rare to see people reinforce the jamb), so, even an naive attempt probably wouldn't be that much worse. For a metal door with a chunky insert, I think it would work fine. For any other kind of door, I think you'd probably need at least a frame or large plate to distribute the loads, but it's still probably wouldn't be much worse than a conventional configuration. Huh...

    I guess the main complexity (or just oddity) would be the keyhole wouldn't be on the door.

    Why not a cable for power? Does the door need to be able to go somewhere that doesn't have electricity?

    Have you tried puttting in a wired power supply instead?

    Rechargeable li-ion batteries are the game changer for me.

    All the fancy expensive rechargeable including Eneloop would have a 30+% failure rate every recharge cycle and I wasted so much money. I have 16 li-ion AAs that I rotate including in my door locks and they have gone through multiple recharge cycles with no failures.

    Rechargeable Eneloops are Ni-Mh which makes the nominal voltage 1.2V where as the voltage on an Alkaline battery is 1.5V. The rechargeable ones are worse than normal Alkaline batteries. You can get rechargeable 1.5V Lithium AA batteries from Nitecore. Those are much better than Ni-Mhs.

    Which lock are you using?

    Been looking at Schlage for a nice local only Zwave / ZigBee lock but I've seen a few recent reviews saying how their quality went down the drain. How the PCB is corroding from just moisture in the air... So I'm open to recommendations.

    Oof. My Yale has a hub and the AAs last 9-12months.
