Support fractional threshold

[yangjiel]

Dear all,

I wonder can we support the fractional threshold number for uv index? Since the openweather does provide an index up to two decimal places. In my area (Vancouver, Canada), day time uv index can be range from 0.1 to 3. And even at 1, it is still very bright outside (I'm living in high rise also). Like UVI goes to 1 at around 3pm in summer while the sun is still high up (you can check the openweathermap). I want to trigger an automation to turn my light on when going dark but the current threshold will not work.

Thank you.

I can submit a merge request to convert the uvi to floating point. But I wonder if Eve can support it as I have little knowledge on Eve.
