Precipitation type (HymecNG)

HymecNG is DWD's classification of what is falling, derived from radar every 5 minutes. The integration reads the class of your grid cell. With Rain events on, it also gives each measured step of a rain event its type.

Precipitation type now

Precipitation type now is an enum sensor: what is falling right now, from the latest 5-minute analysis, like Precipitation intensity now.

State	Shown as
no_precipitation	No precipitation
not_classified	Not classified
drizzle	Drizzle
rain	Rain
freezing_drizzle	Freezing drizzle
freezing_rain	Freezing rain
sleet	Sleet
snow	Snow
graupel	Graupel
hail	Hail
large_hail	Large hail

Automations and templates use the state on the left; the dashboard shows the translated label on the right.

No precipitation or unknown

DWD's file tells two situations apart, and so does the sensor:

• no_precipitation: the radar scanned your location and saw no echo. It is dry.
• unknown: the file has no data for your location: a radar has dropped out of DWD's composite, or the location is outside the area HymecNG covers. The log says which, once.

Example

Notify when freezing rain is classified at home:

triggers:
  - trigger: state
    entity_id: sensor.home_precipitation_type_now
    to:
      - freezing_drizzle
      - freezing_rain
actions:
  - action: notify.notify
    data:
      message: "Freezing rain at home: watch out for black ice."
