I think it is more about the power required to run the lock motor.
I have several z-wave door locks as well. They all need battery replacement within a few months. Unless I don’t open/close them very often. They can go much longer.
But it really isn’t to big of a deal. Home Assistant tells me when they are getting low and I just swap the batteries in a few minutes.
That is fucking dumb that you have to replace the battery every month.
We have low power mcu that can go down to a few uA and make battery last for years, but this company decided that it was beneath them.
Bad engineering overall.
Honestly the most any smart door lock las lasted us before the low battery has been 1-2 months. I ended up just going to a old fashion lock and key
No wonder. The hassle of changing the batteries so often is not worth it.
