   - **winddirection**: Where the wind is coming from: N (North),Z (south), NO (Noth-East), etc.
   - **windazimuth**: Where the wind is coming from in degrees, with true north at 0° and progressing clockwise.

   - **precipitation_forecast_average**: The average expected precipitation/rain in mm/h within the given timeframe.
   - **precipitation_forecast_total**: The total expected precipitation/rain in mm within the given timeframe. The total expected rain in the configured timeframe will be equal to _precipitation_forecast_total_/_timeframe_ mm/min. So, with timeframe configured to 30 minutes and a value of 5, the expected rain is 5 mm in 30 minutes, which is the same as 10 mm/h. If timeframe is set to 90 minutes and a value of 5, the expected rain is 5 mm in 90 minutes, which is equal to 3.3 mm/h.
