I've been seeing a funny thing for a while and finally got down to try to figure this thing out.
I have built a couple sensors with the BH1750 light sensor.
I know the sensor works and that the lux value is transferred to the gateway and read into OpenHAB, as seen here (this is pulled from debug logging from Karaf in OH2.1):
4;1;1;0;0;24.0
0;255;3;0;9;TSF:MSG:READ,4-4-0,s=0,c=1,t=1,pt=7,l=5,sg=0:52.3
4;0;1;0;1;52.3
0;255;3;0;9;TSF:MSG:READ,4-4-0,s=2,c=1,t=37,pt=3,l=2,sg=0:30
4;2;1;0;37;30
0;255;3;0;9;TSF:MSG:READ,4-4-0,s=255,c=3,t=0,pt=1,l=1,sg=0:31
4;255;3;0;0;31
0;255;3;0;9;TSF:MSG:READ,4-4-0,s=3,c=1,t=16,pt=0,l=1,sg=0:0
4;3;1;0;16;0
Light level is child sensor 2.
What bugs me is that each value gets transferred into an appropriate item, except for light level, as seen here:

It looks like the value for light just gets ignored.
I added light sensors via PaperUI by manually adding a thing and then an item from that (not using Simple mode).
The code for the sensor is pulled directly out of the example and in Arduino debug, the value is properly given.
Does anyone else have this problem?
