Continuing the discussion from Hub 2.0 with new install:
I get very good battery life with my wireless door locks, a year to 14 months for 4 AAs.
The main thing affecting battery life on a door lock is how often it has to wake up.
So the first thing is to look at your network traffic and see if you have set up polls or refreshes that might not really be needed. Ideally polling should be limited to no more than 5% of network traffic. Nothing kills batteries faster than frequent polling.
Next is just how often the lock is actually used. Ours gets used about 20 times a day. But in some households it could be over 200. It just varies.
Third, of course, is the quality of the batteries themselves.
Fourth, locks with anti bump or anti theft built in may wake up a lot more often to evaluate vibration, even trucks going by, even if ultimately the lock decided it’s not an alarm-worthy event.
So there’s definitely a lot of variation. Wired locks are an option, but typically require replacing both door and frame.
An alternative is an automatic door opener which has the wired side on the wall and a mechanical actuator to open the door. Open Sesame makes one. But these are very visible from the inside, not everyone likes the look or the cost. They do preserve the look from the street, though.
