Send message to raspberry pi

Good morning, my project aims to send a text message to the raspberry display on the screen, i’m thinking of using blynk, but from what i saw, only have the terminal to send strings to the raspberry, would you have any other ideas? Thanks for the help and sorry for bad english, it was google translator.

So far that is the only real method of sending non-preformatted text to somthing… but hopefully there will soon be another text widget on the way.
