listen_only: true configuration option ignores rtlamr settings

[BrettEBowman]

I am running rtlamr2mqtt version: 2.2.1. I am trying to change the centerfrequency and run in listen_only mode to see what meters I can find. However, whenever I enable listen_only mode, then the centerfrequency parameter is ignored.

For both of these tests, custom_parameters includes:
rtlamr: '-unique=true -centerfreq=915000000 -symbollength=32 -tunergain=40'

With listen_only=true, the logfile shows:

Hi @BrettEBowman , this is due how the listen_mode was originally designed: to ignore the configuration file.
It is possible to pass these parameters using environment variables to the Docker container, but I agree it is not the best for the addon.

I am going to add this feature in the next minor release. :)

[BrettEBowman]

Great. Thanks!

I am rewriting the whole project and this will be in the new version!
