I did look at the core RSS integration, but it seems (I may be wrong) that it only generates events and doesn’t populate a sensor. I’m not sure whether it’s possible to create and populate sensors from automations triggered by the events and it sounds like it could get complicated.
I’ll take a look at Feedparser though, that looks interesting, thanks for the info.
Hi,
Did you had the chance to update the Lovelace Config? I’m curious about it! 
Cheers
not sure what you mean.
they have recently changed their format, I now use this:
- type: markdown
style: "ha-card { --mdc-icon-size: 60px; }"
content: |
{% if state_attr('sensor.weather_warnings','items') != None %}
{% for item in state_attr('sensor.weather_warnings','items') %}
{% for type, icon in [('rain', 'weather-pouring'), ('thunderstorms', 'weather-lightning-rainy'),
('wind', 'weather-windy'), ('snow', 'weather-snowy-heavy'),
('lightning', 'weather-lightning'), ('ice', 'car-traction-control'),
('fog', 'weather-fog')] if type == item.description[0].split(' ')[3]|trim(',') %}
---
| | | |
| --- | --- | --- |
| <font color = {%- if 'Yellow' == item.description[0].split(' ')[0]|trim(',') %}'gold'
{%- elif 'Amber' == item.description[0].split(' ')[0]|trim(',') %}'darkorange'
{%- else %}'firebrick'
{%- endif %}><ha-icon icon={{ "'mdi:" + icon + "'" }}></ha-icon></font> | | {{ item.description|trim("'[]'") }} |
{% endfor %}
{% endfor %}
{% endif %}
Thanks! It helped me a lot to improve my code! great stuff
Sorry, not been around for a while. They changed the format a few weeks back, my code now looks very similar to what you’ve posted. I’m sure it will help others, thanks.
I have started a new thread around the new(-ish) Met Office DataHub but maybe someone here has already got the necessary to help me with this.
How do I get the JSON from my python calls into Homeassistant and one of your lovely cards?
Thanks
for any one interested. I’ve got this working with feedparser rather than nodered. Massive props to @eggman as I wouldn’t have been able to do this with their work.

I’ve made some improvements to my feedparser version previously posted. This now supports “extream heat” and “thunderstorm” alerts. I’ve also reworked the summary text into something which I can layout a little better. Date time formats can be changed to your liking simply by updating the format codes.
You will also need to update the region in the regex to match your region. I strip it out because I know my region and only interested in the actual places affected.

Hope someone finds this useful
Thank you for this! exactly what I have been looking for
You are most welcome. Credit to the OP for coming up with the idea in the first place.
If anyone else spends hours trying to get this working, don’t forget to edit this regex:
regex_findall_index('(.*) affecting West Midlands: (.*) valid from (.*) to (.*)', ignorecase=True) %}
and change West Midlands to whatever is reported in your sensor.weather_alerts state!
Hi I am having problems with this. I am using this feed trying to capture alerts for London: Met Office warnings for London & South East England
I recently configured this OK using the details above. For South East change the last part of the URL in the Feedparser sensor from “wm” to “se” and in the Lovelace card change “West Midlands” to “London & South East England”. You’ll need to add Feedparser via HACS if you don’t already have it. I used the standard “vertical-stack” for the cards - you’ll need to add “stack-in-card” via HACS if you want to use that.
Ah perfect 
Ok, I don’t post this here because I’m particularly proud of it, in fact I wholeheartedly welcome improvements…
This is a sensor with a state of the number of current weather warnings with the attribute ‘warnings’ giving a list of current warnings and the validity period in natural language.
For example currently my sensor shows this:
As I said I just post it here in case it is interesting to anyone, not as an example of great coding!
I use it for phone notifications. Persistent notifications and as others do here, a Lovelace card.

Curious to see if anyone is generating notifications when their sensor.weather_alerts entity increases by one and if anyone can think of a better way to handle a notification to say a new alert has been issued:
alias: Weather Alerts
description: 'Send notification when a weather alert is issued'
trigger:
- platform: state
entity_id: sensor.weather_alerts
condition:
- condition: template
value_template: '{{ trigger.to_state.state | int > trigger.from_state.state | int }}'
action:
- service: notify.mobile_app_nick
data:
message: https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings
title: 'Check Weather Warnings! '
mode: single
I’m not sure if this is the answer to your question but I think so…
And as previously stated this was all written ages ago, it’s not great code but it works so I leave it alone.
I allow for up to five warnings at any one time;
#================
#=== Input Texts
#================
input_text:
weather_warning1:
min: 0
max: 255
... etc ...
weather_warning5:
min: 0
max: 255
I have the sensors as my previous post.
And I have this automation that saves the warnings:
#==============================
#=== Populate Weather Warnings
#==============================
- alias: Weather Populate Weather Warnings

trigger:

entity_id: sensor.met_office_london_weather_warnings

- input_text.weather_warning5
value: ""
#=== Check there are any weather warnings for London
- condition: numeric_state
entity_id: sensor.met_office_london_weather_warnings
above: 0
#=== Populate the input text for each warning
- repeat:
count: >
{{ states('sensor.met_office_london_weather_warnings') }}
sequence:
- service: input_text.set_value
data:
entity_id: input_text.weather_warning{{ repeat.index }}
value: >
{% set warning = state_attr('sensor.met_office_london_weather_warnings', 'warnings')[repeat.index-1].warning %}
{% set warning = warning.replace('affecting London & South East England)', 'affecting London') + '. ' %}
{% set period = state_attr('sensor.met_office_london_weather_warnings', 'warnings')[repeat.index-1].period %}
{{ warning + period }}
And this automation that handles the notifications (script.notify is my notification engine):
#===============================
#=== Notify of weather warnings

By way of thanks for this great contribution, just to note that current UK weather warnings seem to be combining “snow, ice” into a single alert, so I needed to add this to the alert dictionary for it to be parsed properly in the markdown card:
{% for type, icon in [('rain', 'weather-pouring'), ('thunderstorms', 'weather-lightning-rainy'),
('wind', 'weather-windy'), ('snow', 'weather-snowy-heavy'),
('snow, ice', 'weather-snowy-heavy'),
('lightning', 'weather-lightning'), ('ice', 'car-traction-control'),
('fog', 'weather-fog'), ('extreme heat', 'weather-sunny-alert'), ('thunderstorm', 'weather-lightning')] if type == item.summary | regex_findall_index('.*warning of (.*) affecting.*', ignorecase=True) %}
... rest of code here
{% endfor %}
Thanks for the heads up.
I was wondering what the code would be to open the BBC weather warnings site, by clicking on the text that this entity generates. Is that possible at all?
