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!
