MQTT Loupe is an intuitive utility to inspect MQTT messages exchanged on an MQTT broker. Connect to any public or local MQTT broker, subscribe to topics and view details of messages being transmitted. Don't remember that one message or topic? Fire up the search to find it instantly using full-text search through all topics, and results updating live with new hits appearing as they arrive. With built-in JSON highlighting, this app is perfect for monitoring Zigbee2Mqtt. And if you need to work with binary message payloads, the built-in hex viewer has you covered.
