Este projeto cria um Blueprint no Home Assistant para monitoramento e notificação de câmeras de segurança que ficam offline. A automação utiliza o notify, mensagens no Telegram e notificações persistentes para informar sobre o estado das câmeras, garantindo que o usuário saiba imediatamente quando uma ou mais câmeras perdem a conexão.
