A bit of googling suggests that this: Extension Name Version Description MQTT 0.2.0 Extension for uploading LOOP data to an MQTT broker
refers to the extension in this repo: https://github.com/michael-slx/weewx-mqtt. Looking through the code for this extension it does not support formatting the MQTT output as you wish to. I'm not sure what if any advantages the Michael-six uploader offers over the matthewwall uploader. As for your re-installlation problem. You appear to be using a package install of WeeWX v5. I know the instructions say to use pip to install paho-mqtt, but I find when you are not using a virtual python environment it is all to easy to end up with a non-functional install when using pip to install some packages. Try using apt to install paho-mqtt: $ sudo apt update $ sudo apt-cache policy python3-paho-mqtt this should show what version of paho-mqtt will be installed, something like: python3-paho-mqtt: Installed: (none) Candidate: 1.6.1-1 Version table: 1.6.1-1 500 500 http://deb.debian.org/debian bookworm/main arm64 Packages 500 http://deb.debian.org/debian bookworm/main armhf Packages Provided the candidate version is 1.6.1 or lower (ie it is not v2.x.y) install paho-mqtt using: $ sudo apt install python3-paho-mqtt You should be able to complete the rest of the uploader install/setup. If it does not work as expected edit weewx.conf, set debug = 2 and restart WeeWX. Post a log extract showing the complete WeeWX startup and the first few MQTT uploads. Also post the output from weectl debug as per instructions in my earlier post. Whether you previously installed paho-mqtt using pip or apt makes no difference to what WeeWX MQTT uploader was installed/used; somehow you separately installed the Michael-six uploader rather than the matthewwall uploader.
