I am trying to add a battery status icon (LED icon) to my control page. The device is a Oregon temp/hum sensor with data collected by rfxtrx. When I select the battery level for the device in CP, I can see that the value is 10 when it shows as text. However, when I try to show it as a colored LED image, it isn't showing anything at all on the rendered web page, but I can see the default icon in the CP editor. I am sure it is just some obvious mistake from my point, but at this time I can't figure it out. I have attached a few pictures showing the CP editor, the file names and the rendered web page. As a demonstration I have both the icon and text version on the pictures.
Any thoughts?
