I want to put a Sonoff Th16 with a external button in a box. When i press the button, i want to have access to the portal of Wifimanager to put a new password. Is this possible? This is the code that i want to use. Thanks for your help!

Code: Select all#include <ESP8266WiFi.h>
#include <WiFiUdp.h>
#include <WiFiClientSecure.h>
#include <ArduinoJson.h> // https://github.com/bblanchon/ArduinoJson
#include <NTPClient.h> // https://github.com/arduino-libraries/NTPClient
