You can use the "MQTT" module with our loggers to receive and publish data using the MQTT protocol. MQTT (Message Queue Telemetry Transport) is a simplified network protocol that runs over TCP/IP. It is used to exchange messages between devices based on the publish-subscribe pattern.

Our logger acts as a client, so it requires a broker server running on your local network or on the Internet (for example, a cross-platform Mosquitto server). You can subscribe to topics and receive data from them using the "MQTT" module only if you use it together with our Data Logger Suite. Usually, data are sent in the text format, so the logger can convert text values to another data type to simplify their further handling. For example, you can log the data received to a file or a database.

You can publish data using any logger that supports data export. The program can also convert data types. If you use the "MQTT" module and our Data Logger Suite, you can automatically group data from different sources and simultaneously publish them at another location.
