Some devices have additional attributes above the standard capabilities. For example, this Airscape fan that I use has three temperature sensors:
But only one of them is available via the "Temperature Sensor" capability under attribute name "temperature". The other two are under different attribute names. I think this is somewhat of a flaw of the SmartThings device model, where SmartThings would consider it as three separate devices. It really isn't though - it's one device with three sensors.
WebCore has support for the additional attributes. I wonder if ActionTiles would consider adding support, where you could map an additional attribute name to one of the support capability types.
