Pin pulled high every +/- 45minutes

Hello Everyone,

I'm having some problems with my Wemos mini.
I run it to control my doorbel.
But every +/- 45 minutes the pin is pulled high and my doorbel will ring.

I have logged when the signal has been send.

I pull down the pin with a resistor and have the switch on the 3.3volt pin and the gpio 13(D7 Wemos)

I'm been pulling my hair on what and why this is happening.

The code below is what handles the button pressed:
unsigned long currentMillis = millis();

// listen for button pressed over here!!!!!
if (buttonState == HIGH ) {
if(sendOnce == false){
// send request
sendOnce = true;
updateMyStatus(PRESSED); // set state to pressed
requestPlay("doorbel");
updateVolumio(START_PLAYING);
digitalWrite(ledPin, HIGH);
delay(100);
digitalWrite(ledPin, LOW);
previousMillis = currentMillis;
} else {
if(currentMillis - previousMillis > interval) {
// save the last time you blinked the LED
if(myStatus != ERROR){
updateMyStatus(ERROR);
}
previousMillis = currentMillis;
}
}
} else if(sendOnce == true && (volumioStatus == IDLE || volumioStatus == OFFLINE ) && buttonState == LOW){
if( volumioStatus == IDLE ) LedBlink();
updateMyStatus(IDLE);
sendOnce = false;
previousMillis = currentMillis;
} else {
previousMillis = currentMillis;
}

If the Problem is that the pin is being pulled high, it doesn't mean much to show us what happens once it is pulled high. We need to see two things, 1) how it is detected (not the Response) and 2) the schematics.

Also, you should read one of the very first posts which is repeated in every forum: how to use. It is explained there how you should properly post your code. Some of the best responders in this Forum often decline to help if you don't follow the rules.

So, read the "how to use", post a schematic, and post your FULL code. Then we'll be able to help.

How is the input wired ? Does it have a pulldown resistor holding it LOW until the button is pressed ?
