Hello, hello!

I was thinking of building a Smart Mirror for my grandma (a little modified to suit her needs, tho) BUT she dosen’t have WiFi… :/

I’ll have WiFi while i’m creating the mirror, but will it work in her house without Internet connection? And is there a way to make it work either way? I’m asuming a voice assistant won’t work either?

Sorry for bad english and allmost no knowledge… XD

//Thx! :D
