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.


Deadbolt doesn’t get locked unless everyone is out of the house.
but it can be locked and the key hidden away
By whom tho? Someone wishing harm to the residents? If they’re already inside they could be more direct.
…were you not a kid at some point, or been around kids?
kids would absolutely fuck around and lock people in as a joke. sure, not all of them, and teaching them is important, but it is non-zero. codes/regulations exist because of dangerous but very unlikely issues
I see your argument, but I’ve never heard of anything like that happening, and locked-both-sides deadbolts are presumably legal in Australia since basically every house has them.
