The Receiver supports MQTT (Message Queuing Telemetry Transport) which can be used on top of the TCP/IP network stack as a lightweight Machine-to-Machine (M2M) messaging protocol to deliver a snapshot of measured critical parameters over networks. Since the MQTT is de facto the standard for IoT messaging, the protocol support provides additional options of integrating a number of the Receivers into a monitoring network covering a significant area.
If Certificate type of security is enabled, required certificate and key files should be uploaded using the MQTT settings page.
