Hotdog, that was it. I made the change in the toml and now it is human readable. This should get me pretty close to being able to do what I want, thanks!
If you want to proceed with mqtt in python I can highly recommend
the paho mqtt client, it works like a charm & is well documented.
I’ve seen a ton of examples all using it, so it seems to be well supported/used.
I need to figure out how to get it installed on the Chirpstack-Gateway-OS since it is not there by default. I am trying to learn how to do the build as we speak (though not with that package). Docker is yet another thing I am bad at, but I am thinking that once I have a build, I should be able to just add it to the build list and move it over (famous last words). I did try to add pip3 to the build process, so if that works, it might make this a lot easier.
