Sorry but it's obvious you don't have kids. You need to know when and how much formula your baby had to not overfeed them. You need to know what a toddler ate if he comes home and throws up/has diarrhea/gets a sudden rash. You need to know when his diaper was changed so you know if you need to change it again when you get home. Etc. You really need that info, and people working in daycare absolutely don't ballpark this as they need to know it as well and they have 18 other kids to take care of so they can't remember it all.

Yeah, charging 50$ to enable hardware they already sold to you is quite something. My model didn't have that option, it only has a bluetooth radio.

Can't complain about the build quality though. It's been rock solid for more than 2 years now, running on 4 rechargeable batteries which seem to last quite long. My first device was from a batch that apparently had radio problems that didn't affect me, but they replaced it proactively anyway. Can't really say anything bad about them from personal experience...

I have a previous version Nuki with a keypad. I think it works great, also locks my door automatically at night. I don't have it connected to anything else however, to limit attack surfaces. You can still use the app, as it uses bluetooth. That in-app purchase is pretty shitty, though the lock itself is not that expensive compared to competitors. I would advise to search for discount codes or wait for promotions, which happen frequently.

Do remember that it requires a key into the cilinder on the inside, so if you don't have a double cylinder you can't use your key on the outside. Which means you can lock yourself out when the batteries die. You should get a cylinder with an emergency function, so you can use a key on one side when a key is present on the other side.
