# Home Assistant - SMHI Weather Warnings & Alerts
Retrieve SMHI Warnings & Alerts in Sweden and trigger actions, view in the home assistant dashboard.
This custom component for Home Assistant fetches data from SMHI open API and parses it. The data
is then divided into a hash map of districts and messages per district. The component can be configured
to notify on all warnings or just for a specific district.
*This component is based on https://github.com/isabellaalstrom/sensor.krisinformation*
## Example Configuration
In configuration.yaml for Home Assistant:
Receive all notifications for all districts:
```
sensor:
- platform: smhialert
district: 'all'
```
Or specify a specific district as below:
```
sensor:
- platform: smhialert
district: '9'
```
Available districts are listed at the bottom of this README.
You can also chose to get the available information in Swedish by adding `language: 'sv'` to your config for the sensor.
## Custom Lovelace Card
Download the smhialert-card.js and place in your *www* folder of Home Assistant.
Configure the UI (raw edit) and add this to the lovelace configuration:
```
resources:
- type: js
url: /local/smhialert-card.js
```
Then you can add a custom card with the following settings:
```
entity: sensor.smhialert
title: SMHI Alerts
type: 'custom:smhialert-card'
```

## Automation Example Configuration
The below example configures an notification both as push notification and as an email notification.
It will use the prefabricated *notice* that is created by the component. It is also possible to
use the data structure and configure the message manually (*sensor.smhialert.attributes.messages*).
In automations.yaml:
```
- id: smhialert
alias: 'SMHI Alert'
initial_state: 'on'
trigger:
platform: state
entity_id: sensor.smhialert
to: "Alert"
action:
- service: notify.push
data_template:
title: "SMHI Alert!"
message: '{{states.sensor.smhialert.attributes.notice}}'
- service: notify.email
data_template:
title: 'SMHI Alert!'
message: '{{states.sensor.smhialert.attributes.notice}}'
```
Example of full attributes that could be used in the data template is as follows:
```
{
"messages": {
"019": {
"name": "Norrbottens län inland",
"msgs": [
{
"event": "Risk Forest fire",
"event_color": "#ab56ac",
"district_code": "019",
"district_name": "Norrbottens län inland",
"identifier": "smhi-bpm-1564087965423",
"sent": "2019-07-25T22:54:41+02:00",
"type": "Alert",
"category": "Met",
"certainty": "Possible",
"severity": "Severe",
"description": "När: Tisdag och onsdag\nVar: I den nordöstra delen\nIntensitet: Risken för bränder i skog och mark är lokalt stor\nKommentar: -",
"link": "http://www.smhi.se/vadret/vadret-i-sverige/Varningar",
"urgency": "Expected"
}
]
}
},
"notice": "[Severe] (2019-07-25T22:54:41+02:00)\nDistrict: Norrbottens län inland\nType: Alert\nCertainty: Possible\nDescr:\nNär: Tisdag och onsdag\nVar: I den nordöstra delen\nIntensitet: Risken för bränder i skog och mark är lokalt stor\nKommentar: -\nweb: http://www.smhi.se/vadret/vadret-i-sverige/Varningar?#ws=wpt-a,proxy=wpt-a,district=019,page=wpt-warning-alla'\n\n ",
"friendly_name": "SMHIAlert",
"icon": "mdi:alert"
}
```
The *messages* contains an hash of districts (if 'all' is used) and each districts has *msgs* which is an array of all active messages for that district.
## Usage Screenshots
## Todo
- Alert if changes has occured. Alert is always triggering when there are _any_ alert and does not
take changes into account.
- Be able to specify multiple specific districts.

```
$ curl -s https://opendata-download-warnings.smhi.se/ibww/api/version/1/metadata/area.json | jq -r '.[] | [.id,.sv] | join(", ")' |sort -h

data:
message: >-
{% set alerts = state_attr('sensor.weather_alert', 'messages') %}
{% for alert in alerts %}
There is a weather alert for the area of {{ alert.area }}. The event is classified as {{ alert.event }} with a severity level of {{ alert.severity }}. {{ alert.details.split('\n\n')[0].replace('What happens?: ', '') }}
{% endfor %}
