Hourly forecast - precipitation always 0

[Benschi99]

First of all: Great integration. Thank you very much for your work.

I encountered one issue: Sadly the hourly forecast doesn't provide the correct precipitation. It's always showing as 0.

Example Daily forecast:

     - condition: rainy
      datetime: "2024-07-16T00:00:00"
      wind_bearing: null
      temperature: 24
      templow: 18
      precipitation: 8.8

Example Hourly forecast (same day):

    - condition: rainy
      datetime: "2024-07-16T00:00:00+00:00"
      wind_bearing: 195
      temperature: 19.4

Can you please show debug level output for the module where the response from MeteoSwiss is visible? It's pretty common for their API to return 0 precipitation as forecast.

[Benschi99]

You are indeed correct, the API returns 0 precipitation very often. Seems very odd to me if it rains the whole day and every hour there is 0 precipitation in the forecast. But you don't have any influence on that.

[izacus]

Maybe we should default to "precipitationMax" variable which tends to show larger numbers, but then I'm afraid it would be overestimating the probability :/
