Summary:To provide a communication system that can reduce the load and provide a user-friendly experience.SOLUTION: A communication system includes an external server, an IoT device that communicates with the external server via a network and sends a device status value indicating the device status to the external server, and an information terminal that has application software that synchronizes with an external server via the network and displays the device status on the basis of the device status value sent from the external server. When the external server receives the device status value, the external server sends a status value change notification to the information terminal to notify that the device status value has changed, and when the information terminal receives the status value change notification, the information terminal requests the device status value from the external server.SELECTED DRAWING: Figure 6 【課題】負荷の低減およびユーザの使用感を両立できる通信システムを提供すること【解決手段】外部サーバと、外部サーバとネットワークを介して相互に通信し機器状態を示す機器状態値を外部サーバに送信するIoT機器と、外部サーバとネットワークを介して相互に同期通信し、外部サーバから送信される機器状態値に基づいて機器状態を表示するアプリケーションソフトウェアを有する情報端末と、を備える。外部サーバは、機器状態値を受信した場合、機器状態値が変化した旨を通知する状態値変化通知を情報端末に送信し、情報端末は、状態値変化通知を受信した場合、外部サーバに機器状態値を要求する。【選択図】図6
