Incorrect Rain sensor
I’m using openweathermap and noticing the rain accessory is reporting rain when there isn’t any.

When I check openweathermap it does not report rain for the same location.

Which specific API is is used ? Not sure if I have a configuration problem or this is a bug.

Here is my config

```
        {
            "platform": "WeatherPlus",
            "units": "us",
            "interval": 5,
            "stations": [

      ]
   }
