I have this binding properly reporting some values, not the rain amount. I put the binding in debug mode and here is what is returned:

The rain amount for the current weather is correct today as we’ve had no rain today, but yesterday we had about 0.5" of rain yesterday but the rain value was always 0.0. I’m using OpenWeatherMap with the weather 1.x binding on an RPi3 and OH2.4.
Is this an issue OpenweatherMap?
