# DWD Precipitation Forecast
**DWD Precipitation Forecast** is a **Home Assistant** component which provides a detailed precipitation forecast for the **next two hours**.
The forecast is derived from the **DWD (Deutscher Wetterdienst) rain radar forecast**. _This integration only works in Germany!_
## Sensors
The integration proveds these sensors:
* **DWD Precipitation Forecast:** The current precipitation intensity (mm/h) at your location
* This sensor also contains attributes with the forecasted precipitation over the next two hours, in 5-minute-steps
* **Next Precipitation:** Information about the start, end, length and intensity of the next precipitation event
* **Precipitation in next 15/30/60min:** Will it rain in the next 15/30/60 minutes?
## Installation
### Home Assistant Community Store (HACS)
1. Open HACS in Home Assistant
2. Select `Custom Repositories`
3. Add `https://github.com/stoppegp/ha-dwd-precipitation-forecast`
4. Select `DWD Precipitation Forecast` and download it
5. Select `Integration` as type
6. Add a new device _DWD Precipitation Forecast_
7. Insert the location name, latitude and longitude
### Manual Installation
1. Download the latest release
2. Unpack the release and copy the `custom_components/dwd_precipitation_forecast` directory into the `custom_components` directory of your Home Assistant installation
3. Restart Home Assistant
4. Add a new device _DWD Precipitation Forecast_
5. Insert the location name, latitude and longitude
## Precipitation forecast card
This is an example for a forecast card that you can create with data from this integration:
To create a forecast card like this, you need following components:
* [Mushroom Template card](https://github.com/piitaya/lovelace-mushroom)
* [easy-time-jinja](https://github.com/Petro31/easy-time-jinja)
* [lovelace-card-mod](https://github.com/thomasloven/lovelace-card-mod)
Use this code for your dashboard:
```yaml
type: custom:mushroom-template-card
primary: >-
{% from 'easy_time.jinja' import custom_time, custom_relative_time,
custom_time_between %}
{% if not is_state_attr(entity, 'next_start', 'unknown') %}
{% if (state_attr(entity, 'next_start') | as_timestamp > now() |
as_timestamp) and (state_attr(entity, 'next_end') is not none) %}
In {{ custom_time(state_attr(entity, 'next_start'), 'hour, minute', 'de')
}} regnet es für {{ state_attr(entity, 'next_length') }} Minuten.
{% elif (state_attr(entity, 'next_start') | as_timestamp > now() |
as_timestamp) %}
In {{ custom_time(state_attr(entity, 'next_start'), 'hour, minute', 'de')
}} beginnt es zu regnen.
{% elif (state_attr(entity, 'next_end') is not none) %}
Es regnet noch für {{ custom_time_between(now() | as_timestamp,
state_attr(entity, 'next_end') | as_timestamp, 'hour, minute', None, None,
'de') }}.
{% else %}
Es regnet noch mindestens 2 Stunden lang.
{% endif %}
{% else %}
Kein Regen in den nächsten 2 Stunden.
{% endif %}
icon: mdi:weather-rainy
icon_color: |-
{% if float(states(entity)) > 0 %}
blue
{% else %}
grey
{% endif %}
entity: sensor.dwd_precipitation_forecast_leipzig
card_mod:
style: |
{% set entity = 'sensor.dwd_precipitation_forecast_leipzig' %}
ha-card {
background-image: linear-gradient(90deg{% set entity = entity %}{% set duration = state_attr(entity, 'forecast').keys() | last | as_timestamp - now() | as_timestamp %}{% set hue_min = 200 %}{% set hue_max = 300 %}{% set prec_max = 20 %}{% for x, y in state_attr(entity, 'forecast').items() %}{% set pos = ((x | as_timestamp - (now() | as_timestamp))/duration*100) | round %}{% set hsl_h = (y/prec_max*(hue_max-hue_min)+hue_min)|round %}{% set hsl_l = 50 if y > 0 else 100 %}{% set hsl_alpha = 0.5 if y > 0 else 0 %}{% if pos >= -4 %}, hsla({{hsl_h}}, 100%, {{hsl_l}}%, {{hsl_alpha}}) {{ max(pos,0) }}%{% endif %}{% endfor %});
}
```
Change `sensor.dwd_precipitation_forecast_leipzig` in `entity` and `card_mod` to your sensor.
