Скрипт для проверки подключенных устройств к домашней сети. Скрипт заставляет Raspberry периодически сканировать домашнюю сеть, чтобы постоянно обновлялась ARP таблица. С помощью этого скрипта можно узнать, кто присутствует дома и какие устройства сейчас включены. Так как не все устройства отвечают на пинг-запрос, это более надежный способ.
