ESP8266 Node MCU 12E and 8 channel relays

Need Help With My Project
1

hello and sorry for my english.
I have an ESP8266 Node MCU 12E and 8 channel relay. This is controlled by Blynk and works very well. When I reset the ESP, all relays are always turned on. But these should be turned off when restarting and only start when I turn them on. I use D1, D2, D4, D5, D6, D7, D9 and D10.
What can I do that when starting the ESP are always all relays off? Request for help. Thanks

PS: everything is running on a local server

You can’t have all relays off at start , due to Nodemcu pin state at start.
Only GPIO 4 and 5 are Low at start

Probably the closest you’ll get is a digitalwrite in setup.

I have solved my problem. In the sketch I had to set pinmode and digitalpin to HIGH and it works. Many thanks

#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[] = "XXXXXXXXXXXXXXX";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "XXXXXXXX";
char pass[] = "XXXXXXX";

void setup()
{
  pinMode(D1, OUTPUT);
  digitalWrite(D1, HIGH);
  pinMode(D2, OUTPUT);
  digitalWrite(D2, HIGH);
  pinMode(D4, OUTPUT);
  digitalWrite(D4, HIGH);
  pinMode(D5, OUTPUT);
  digitalWrite(D5, HIGH);
  pinMode(D6, OUTPUT);
  digitalWrite(D6, HIGH);
  pinMode(D7, OUTPUT);
  digitalWrite(D7, HIGH);
  pinMode(D9, OUTPUT);
  digitalWrite(D9, HIGH);
  pinMode(D10, OUTPUT);
  digitalWrite(D10, HIGH);

  
  
  // Debug console
  Serial.begin(9600);

  //Blynk.begin(auth, ssid, pass);
  // You can also specify server:
  //Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 80);
  Blynk.begin(auth, ssid, pass, IPAddress(192,168,0,19), 8080);
}


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