hi. i am using nodemcu esp8226 in my home automation project. problem is that, when wifi off, all switches remain ON as on connection. my code is
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "d89adaa1a4f742b58ced23d60.........";
// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "----";
char pass[] = "roora";
const int Relay_1 = 16; //D0
const int Relay_2 = 5; //D1
const int Relay_3 = 4; //D2
