Quite often Vera will decide what the type of a device is based on the "Command Classes" that the device reports that it supports. This can sometimes mean that a device that supports multiple different Command Classes will be classified incorrectly by Vera.
Frequently the incorrectly classified device will only result in a "cosmetic" issue in the Vera UI, the actual device will function perfectly. Unfortunately for this particular device, the icon in the Vera UI is completely unrelated to the function the device is supposed to have!
Fortunately, it is actually possible to change the "device_file" for the device so that it shows a more appropriate icon in the Vera UI.
