Tired of expensive disposable batteries and rechargeable AA suck. So I made a 10k mAh pack for my deadbolt.
(sh.itjust.works)
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.
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.
Unless you've got a steel reinforced frame bolted into the foundation backing your steel reinforced door, a strong leg and a sturdy boot will get through practically anything you can buy at a hardware store, and a crowbar will take care of the rest.
So does me forgetting to lock the door.
I once left my garage doors open all weekend with thousands of dollars of tools in it, along with my motorcycle with the key in it. My garage at the time was quite visible from a very busy street. I got lucky and nothing was stolen. My garage doors are smart now, so that doesn't happen any more. Sure, someone could hack my home assistant server and open the garage, but that's way less likely than my continued pattern of forgetfulness.
Based on that logic, my house also has smart locks now that automatically lock when I leave. I will say that they aren't cheapo who-knows fingerprint locks, they're made by a real company and just have a keypad with a lengthy entry code. The only added vulnerabilities should be my home assistant server and the entry code.
