MQTTProbe: MQTT Client

MQTTProbe is an MQTT diagnostic tool built for industrial IoT. Connect to your broker, explore topics, inspect messages, chart live data, and publish payloads from your mobile device. Commission devices, troubleshoot connections, and check live telemetry. Browse a topic tree, manage subscriptions, and inspect message payloads. Decode Sparkplug B messages and metrics alongside standard MQTT traffic. Use the built in emulator to generate test messages and exercise your MQTT setup. Connect to local or remote brokers, with TLS and client certificates for mutual TLS authentication. Save connection profiles for repeat use. No app account or sign in is required. Connect to your own broker or try an included public test broker. Messaging features require a reachable MQTT broker.
