Wow super

Here's the code:
#define BLYNK_TEMPLATE_ID ""
#define BLYNK_TEMPLATE_NAME ""
#define BLYNK_AUTH_TOKEN ""
#include
#include
char auth[] = ""; // Blynk Auth Token
char ssid[] = ""; // WiFi Network Name
char pass[] = ""; // WiFi Password
int sensorPin = A0; // Soil Moisture Sensor Pin
int relayPin = D0; // Relay Pin
int threshold = 40; // Moisture threshold percentage
BLYNK_WRITE(V3) {
int buttonState = param.asInt();
Serial.print("Button state: ");
Serial.println(buttonState);
if (buttonState == 1) {
digitalWrite(relayPin, LOW);
Serial.println("Water pump turned ON");
} else {
digitalWrite(relayPin, HIGH);
Serial.println("Water pump turned OFF");
}
}
void setup() {
Serial.begin(115200);
Blynk.begin(auth, ssid, pass);
pinMode(sensorPin, INPUT);
pinMode(relayPin, OUTPUT);
digitalWrite(relayPin, HIGH);

Even after running the code I am getting an error in the 39th line which is telling me to specify the template ID and name. But I have verified it several times and it's always correct idk why it's showing error

[@Dehcjemkeihhehu3709]

How can we get the code?

@@Elextrolyte In code you set relayPin = D0 but in the vdo, u r showing to connect relay IN with esp8266 D1
