Why would anyone buy a "smart" doorbell with batteries, lighting, and other useless crap only there to fail? I could see it's convenient when renovating and having forgotten to do the wiring, or to pimp a condo for sale, but otherwise you can get the same Honeywell ding-dongs for 10-15 bucks plus converter plus 8V panel that we've used for ages, and that last basically forever.
It’s just Amazon being a dick. Smart home stuff, especially with home assistant, works well and without internet, self hosted, many things even have fallbacks for when there is no connection to your home assistant server. But Amazon makes smart home the iot hellhole that we thought we left behind. Well then.
And no, smart home is convenient even for normal houses.
