Impulse mit Shelly Plus i4 zählen? Script möglich?

let sw1_counter = 0;
let sw2_counter = 0;
let sw3_counter = 0;
let sw4_counter = 0;

Shelly.addEventHandler(function (event) {

  if (event.name === "input") {

    print("Input ", event.id, " is ", event.info.state ? "on" : "off");
  
    if(event.info.state == true){
      switch(event.id){
        case 0:
          sw1_counter += 1;
          break;

          sw2_counter += 1;
          break;
