Timerdaten auslesen (z.B. timer_remaining) verbessern ?

Shelly.addStatusHandler(function (e) {
    print("JSON-st: " + JSON.stringify(e));
    if (e.component === "switch:0") {
       if (e.delta.output === true) {
          Shelly.call("http.get", { url:'http://127.0.0.1/relay/' + 0 },
             function (result, error_code, error_message) {
                //print("Result: ", JSON.stringify(result));
                let jsonData = JSON.parse(result.body);
                print ("Timer: ", jsonData.has_timer);
                print ("Timer_duration: ", jsonData.timer_duration);
                print ("Timer_remaining: ", jsonData.timer_remaining);
             }
          );
       }
    }
});
