Hello sir
hope you fine .
I want to inform you about codeing.
I apply this code in my node mcu esp8266 v2 board.
There is problem with on /off button .
When I connect node mcu with 4 really chanel .
It's continue on the really .
And when I operate from my smart phone ( on state act off ) (off State Act on ).
It's totally opposite.
Sir tell me the solution .
Thank you.....

[@SMEDehradun]

hi
replace this in to your code and it will work for you
BLYNK_WRITE(V0) {
int val1 = param.asInt();
if (val1 == 1) {
digitalWrite(Device1, LOW);
delay(10);
}
else {
digitalWrite(Device1, HIGH);
delay(10);
}
}
BLYNK_WRITE(V1) {
int val2 = param.asInt();
if (val2 == 1) {
digitalWrite(Device2, LOW);
delay(10);
}
else {
digitalWrite(Device2, HIGH);
delay(10);
}
}
BLYNK_WRITE(V2) {
int val3 = param.asInt();
if (val3 == 1) {
digitalWrite(Device3, LOW);
delay(10);
}
else {
digitalWrite(Device3, HIGH);
delay(10);
}
}
BLYNK_WRITE(V3) {
int val4 = param.asInt();
if (val4 == 1) {
digitalWrite(Device4, LOW);
delay(10);
}
else {
digitalWrite(Device4, HIGH);
delay(10);
}
}

Change wifi name and password in the code.
Wifi name & Password must be without special character.
