What is a MQTT Topic?

A MQTT topic is a text string created by the MQTT network administrator to reference or address data. A topic may include a single data point or multiple related points. These topics are then subscribed to by the end user, or client. Topics use forward slashes (/) as level separators and enable publishers to send data while subscribers receive it through the MQTT broker. Wildcards (+ for single-level, # for multi-level) allow flexible filtering and organization of IoT data streams.
