thx for your help, BLOZZY

It list this message in your logs.

Any updates on this?
Does this mean you need no rtl_433.conf file whatsoever? It did create a template conf file on installation however.

After you make the file you need the add on to consume it via the configuration option at the top of the page, put in the relative path to the file, make sure to save, then it will prompt you for a restart
