It has 1.1k installs sharing analytics and was last updated October 27, 2026. MQTT Explorer is a Home Assistant app for browsing the topics and messages on an MQTT broker. It runs the web edition of the MQTT Explorer desktop application and opens as its own page in the Home Assistant sidebar. Every topic is shown in a searchable tree with its last message, how often it changes and its earlier values. Values can be plotted as they arrive, and messages can be published back to the broker. If a broker app such as Mosquitto is installed, its address and credentials are added to the connection list as Home Assistant and refreshed on each start; other brokers, including TLS ones, can be added by hand. It needs Home Assistant OS, runs on aarch64 and amd64, and is reachable only through Ingress. Automatic summary of the docs and configuration of hassio-addons/repository.
