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.


it is non-zero
also yes, one small key is exactly the kind of thing that can be difficult to keep track of. did it fall out of my pocket? which backpack pocket was it in? did it clip in properly? do I need to carry a lanyard now too to keep track of it?
or like just don’t worry about that at all. clear improvement.
Enjoy your self imposed helplessness, I’ll keep using a fucking keychain.
you’re on a weird mission here
I’ll keep enjoying my freedom and not being chained to paying attention to carrying around a tiny object
