What do you think about my Smart Home app idea

Hello everyone,

I have an idea for a really cool smart home app and I am currently working on it. I would like to tailor it to parents and families so I would like to ask you for feedback. Basically my app would allow you to use bluetooth keychains and stickers to track physical objects (kids toys, books, keys, wallets etc) but also would have very precise notifications built it. It means you could get an automatic notification when your kids get home or you could set up notifications on your kids phone to call you when they get home etc. What would you think about such idea? Do your kids lose things and forget about tasks a lot? Any suggestions will be greatly appreciated!
