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.
At this point I’m quite heavily invested in smart home tech, but smart locks are one of the few things I haven’t touched.
Any exploit found in these devices could be packaged into a smartphone app and easily accessed by anyone. Someone hacking the lock that way would look no different to a legitimate user. Firmware updates for these devices seem sporadic at best.
It’s a security concern I don’t want to have to worry about, even if there are convenience benefits.
Anyone can also buy lockpicks, break a window, kick the door down, my electronic lock isn’t even Bluetooth or use a phone app, so that’s not even a possibility with the majority of them.
Hacking it would require technology and skills not everyone has, there’s easier ways to get in your house than to hack it. If that’s your worry, than you better not use your deadbolt at all. It can be picked in seconds.
Unless you’ve got a reinforced door and frame, a deadbolt isn’t stopping anyone from getting in.
You can buy keypad entry deadbolts that don't connect to external wireless devices. I find they're a good compromise between convenience and security.
