I replaced them in April. Should have had another 6 months or more but instead the charge is now at 1%… previous batteries lasted almost 18 months.
No particularly interesting history. Automations locked or unlocked it about 6 times over that 2 day period.
Not a question, just a frustration.


I’ll probably replace the batteries and see if it happens again. It’s a bit humid but not cold here as we head into summer, so maybe?
Depending on how the batteries are mounted you could probably make a usb battery shim with a long enough cable, some planning and then never ever having to think about it again
I don’t think there’s a way to do that without making it look odd! I have a home assistant notification when the batteries get low, and they normally last over a year, so I’m happy to just change them as needed 🙂
