Home Assistant get_library with search

[UKenGB]

I am using the HA get_library command to retrieve a list of the radio stations I have in MA and using the 'Search' field I can get a list of e.g. all BBC radio stations. But…

How can I get a list of all stations EXCEPT the BBC ones?

I can find no documentation on how to use that 'Search' field. Is it possible to somehow exclude items that match?

You dont say what you want to do with it and this is really a HA templating question but something like this will give you the filtered response.

- action: mass.get_library
  data:
    media_type: radio
    limit: 500        # set high enough to get all stations
  response_variable: library_response

- variables:
    non_bbc_stations: >
      {{ library_response.items
         | rejectattr('name', 'search', 'BBC', ignorecase=True)
         | list }}

Thanks, yes I can filter it in the template, but there is a specific 'Search' option and text field to restrict the results returned from the get_library call, rather than then filter the whole list once it's been returned. However there is no documentation on how that search string is used.

I have entered 'BBC' and only then receive all the radio stations that start with 'BBC', with no special templating, but it's not clear if that search is specifically matching to the start of the Name, or just contained anywhere in the Name.

I could test that, but I would like to retrieve all non BBC stations. Is that possible using this search option (i.e. not in any later template)? Is there any way to construct such a search string? Is negation supported and if so, how? Are wildcards allowed and if so which ones and how?

The search could be a very useful feature, but there's no information I can find about how it can be used.

If it really is just a basic 'contained somewhere' type of search, then I'll have to do it in the template, which I can do, but ideally prefer to limit the response rather than throw away later what I don't need.

No you can’t do a NOT search. No wildcards. It is just looking to match the word or phrase anywhere in the item name.

Ok, thanks for confirming that. I'll work it into a template.
