    //    0.

    //    reading was not significantly different compared to initial, for
    //    privacy reasons, service returns the initial value.
    // 5. New value is set to 49. And test checks it is correctly rounded to
    //    50. New value is allowed as it is significantly different compared
    //    to old value (24).
