A sewing machine detects a sewing status after a change, when the sewing status changes. When the sewing machine receives a status request requesting the sewing status, from an information terminal via a LAN, the sewing machine transmits, to the information terminal, sewing status information that accords with the detected sewing status. When the detected sewing status satisfies a predetermined condition, the sewing machine transmits a notification request, which includes identification information identifying the information terminal, to a server, in order to cause the server to transmit, to the information terminal, a notification command instructing a push notification in the information terminal.
