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.
I’m not sure I understand how that’d work. How would they know when the door was closed so they could automatically lock the deadbolt? Or would you need to use a key to close the door from the outside?
They are expensive, but they do exist, it’s called a mechanical keyless deadbolt. A local makerspace put one on their back entrance so that members/employees can come and go after hours without having to give everyone a key or use a smart app.
Ohhh, there is a keypad but it’s mechanical. Neat!
The one I’ve seen was mechanical, not electric. The interior handle can open the door irrespective of the door being locked or not.
