A ‘Number’ item like this
Number Weather_Wind_Degree "Wind direction [%.0f °]" <compass> (Weather) {weather="locationId=home, type=wind, property=degree"}
has states with float values like 200.00 (the .00 digits are always zero in just this case, I’m looking for a general solution though).
I created a few graphics using this script to generate images for every 10° difference:
#!/bin/bash
for i in `seq 0 10 359`;
do
convert -rotate $i -background transparent compass.png compass-$i.png
done
resulting in images like
compass-0.png compass-10.png compass-20.png compass-30.png ...
In the Basic UI, one icon is requested via URL /icon/compass?state=130.00&format=png which shows only the basic image compass.png.
OpenHAB should always show the closest icon to the current state, for e.g. 131° will use the 130°. For now even converting between integer and float states is not working:
/icon/compass?state=130&format=png shows the 130° image
/icon/compass?state=130.0&format=png shows the standard image
/icon/compass?state=130.00&format=png shows the standard image
/icon/compass?state=131&format=png shows the standard image
Am I using the icon engine wrong?
