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.

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.

The motor runs only for a second or two each time. In the moment, it takes more current, but otherwise isn't that active.

If I had to change the batteries once or twice a year, I could probably live with that. But every month or so? Bad engineering

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.
