Hello,

Is it possible to add rule to mosquitto logger to log explicit topics?

I need to find which connected device is messing in shared topic among multiple publishers. I know I could set-up another PC with opened terminal to run mosquitto_sub and pass output to file but I’d like to know if there is a better solution to obtain it. Mosquitto logs only broker-related informations.

I might have found solution in this documentations but where can I find mosquitto.conf ?

I tried to change config by adding field in addon panel -> mosquitto -> config but save button seems not to be working
