Filtering

[nTx-Cheerok]

Hi im using this component for some time now and it generellay works great with the custom lovelace card. However i was wondering if i could filter the entries of a feed efficiently without the need to fiddle around with template sensors. Like only show titles that include a certain string or something like that. The reason i ask is that i kind of get it working with templates but not optimally.

@nTx-Cheerok can you show me an example for the templating?

Me too, I use an RSS feed for weather alerts; the feed covers an entire region, but lists the cities affected in the "locations" field of each alert; it'd be nice to stick a regex on that field to only show alerts which affect my city.

I scripted the last hours and got this to work:

` template:

• sensor:
  • name: "(TEST) RSS" state: "{{ states('sensor.rss_feed') | int }}" attributes: entries: >- {% set rss_list = namespace(entries=[]) %} {% for entries in state_attr('sensor.rss_feed','entries') -%} {% if "filter1" in entries['title']|lower or "filter2" in entries['title']|lower or "filter3" in entries['title']|lower -%} {% set rss_list.entries = rss_list.entries + [entries] %} {% endif -%} {% endfor %} {{ rss_list.entries }} `

Hi peops, i was very busy and this also kind of an old post :D I switched setups and erased some stuff, including the stuff i needed the feed parser for. Ill see if i can find my old backups as the config must still be in there and post my example.

@Vitani Could you post the URLof the RSS feed that you use for weather alerts here?

@ogajduse this is the specific one I use - http://www.metoffice.gov.uk/public/data/PWSCache/WarningsRSS/Region/em, but there are more of them - https://www.metoffice.gov.uk/weather/guides/rss

Not sure how useful they will be right now, as there are currently no weather warnings in place for the UK

Edit: There are rain & thunderstorm warnings today, here's the feed -

I would like to filter these items so that if the description contains "Leicester" then it is shown (so in the example above I would only see the "Yellow warning of thunderstorm" item
