Fibaro Motion Sensor и освещенность

Настраиваю 40 параметр - по умолчанию он 200 люкс, для постоянно темного коридора это очень много, мне необходимо 20, а еще лучше 10, в нем максимум в летний солнечный день 150 люкс. После того, как меняю параметр на 10-20 и включаю например свет в коридоре, в логах начинается вот такое.... Оно конечно работает, но почему такая частая отправка ? При выключении посылки прекращаются до след. включения.. Если я правильно понял, отправка должна быть один раз, в связи с изменившейся освещенностью или нет ?
