Protocol supported by Captia Connect
MQTT in Captia Connect: how data published to a broker is ingested
Lightweight pub/sub messaging for telemetry. Connect subscribes to the relevant topics and normalises the payloads. Connect acts as a client subscribed to the broker topics, normalises the payloads into time series and applies local buffering if the broker or the network uplink drops.
What it is and the role it plays
What is MQTT and how does Captia Connect use it?
MQTT is a lightweight pub/sub messaging protocol over TCP designed for telemetry, with a central broker, hierarchical topics and QoS levels from 0 to 2. In Captia Connect it is an acquisition route: Connect acts as a client subscribed to the relevant topics, normalises the payloads into time series and applies local buffering if the broker or the network uplink drops.
