Right, that’s curious. I double checked all my installed Marketplace Bindings and none of them have the option to change log level. If I drop them into addons folder I can change it! Seems I need to file an issue!
But you can also change it via UI in the API Explorer in logging section. See attached picture and request boday below
{
"loggerName": "org.openhab.binding.mercedesme",
"level": "TRACE"
}
