Sync button in app with relay status

Solved
6

I really wish it was so easy GTT.

When i add that function, nothing happend. The button works , but no feedback when i remove power from Relay or my Wemos D1 Mini.

Btw. in serial print i only get “0” state all the time when i tries to read the coffee switch.

Here is the code i tried:

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

//Put WiFi cridentials and token here----------------------------------

char auth[] = "****";
char ssid[] = "****";
char pass[] = "****";

//---------------------------------------------------------------------

int coffeeSwitch = 5;

BlynkTimer timer;


void setup() {
  Blynk.begin(auth, ssid, pass);
  Serial.begin(9600);
  digitalWrite(coffeeSwitch, HIGH);
  pinMode(coffeeSwitch, OUTPUT);
  timer.setInterval(1000L, buttonUpdate);
}

void buttonUpdate() {
Blynk.virtualWrite(V1, digitalRead(coffeeSwitch));
Serial.print(digitalRead(coffeeSwitch));
}

BLYNK_CONNECTED() {
  Blynk.syncAll();
}

BLYNK_WRITE(V1) {
  int pinValue = param.asInt();
  digitalWrite(coffeeSwitch, pinValue);
}

void loop() {
  Blynk.run();
  timer.run();
}
