    I’m assuming you are running Home Assistant OS and have mosquito installed as a home assistant addon (otherwise, you would have set up mosquito broker manually and already know the answer).<\/p>\n

    The answer depends on where you are trying to access mqtt from.<\/p>\n

      \n
    • If you are trying to connect to it from within HA itself or from some other addon (e.g. NodeRed), then you should use the hostname\u00a0core-mosquitto<\/strong>\u00a0and port\u00a01883<\/strong>. This hostname is managed by automatically (by home assistant os\/docker) and will always map to the correct addon. But it only works from inside the ha\/addon ecosystem so…<\/li>\n
    • If you are trying to connect to it from some other machine on your LAN (e.g. from some smart device), the mosquito broker addon is listening on port 1883 on the same IP address and hostname as home assistant itself. For example, if your rPI is on your network as ”homeassistant.local” then your mqtt broker will be\u00a0homeassistant.local<\/strong>\u00a0port\u00a01883<\/strong>. Or if your rPI has no hostname and you access it only by IP address like 192.168.1.10, then the broker will be 192.168.1.10 port 1883<\/li>\n<\/ul>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

      The Home Assistant MQTT broker address is\u00a0typically the local IP address of your Home Assistant instance, with the default port being 1883<\/mark>. If you’re using Home Assistant OS and haven’t changed the default settings, you can also use\u00a0homeassistant.local<\/code>\u00a0as the hostname.<\/span><\/p>\n

        • If you’re connecting from outside your local network, you’ll need to ensure your router is properly configured to forward MQTT traffic to your Home Assistant instance.\u00a0<\/span><\/span><\/span>\n
