temperatureFilePath Temperature Rounding incorrectly
cubilon has mentioned this already in #334 but I can't see an associated issue anywhere else. If there is one, let me know.

The issue is that when reading the current temperature from a file there isn't any rounding. The temperature is simply concatenated. For example, if the temperature is 18.9 it shows in the Home App as 18 when it should be rounding up to 19.

I've been able to get around this by adding 0.5 to the temperature when I'm outputting (awk '{print $1+0.5}') it but now I'm wanting to use the same value elsewhere so I'd prefer to have the correct value in the file.
