I can input the data I want but if the board reboots it doesn’t remember the the data and i have to do it again from the numeric input again.

Blynk is a platform with iOS and Android apps to control
Arduino, Raspberry Pi and the likes over the Internet.
You can easily build graphic interfaces for all your
projects by simply dragging and dropping widgets.

*************************************************************
This example runs directly on ESP8266 chip.
Note: This requires ESP8266 support package:
https://github.com/esp8266/Arduino
Please be sure to select the right ESP8266 module
in the Tools -> Board menu!
Change WiFi ssid, pass, and Blynk auth token to run :)
Feel free to apply it to any other example. It's simple!-
