Same here but I modified the plugin and it works!
Enabling debug in the Plugin revealed that the Cree bulb is not returning a 'modelid'. It returns a blank ''. So I added '' to the kLivingWhitesDeviceIDs variable in the plugin.py file of Nathan's excellent plugin.
Here is the modified statement in version 1.3.10:
kLivingWhitesDeviceIDs = ['LWB001', 'LWB003', 'LWB004', 'LWL001', 'ZLL Light', '']
Notice the , '' at the end of the list. I reloaded the plugin after the edit.
When defining a Cree choose the "LivingWhites" model. Now it works.
Nathan, I know this is not an elegant solution but I was glad to see that it worked. I suppose the right fix is to get Cree to include a modelid. Do you know if the modelid is a part of the ZigBee standard? If so, I will ask Cree to add a model in their future bulbs.
Thanks again Nathan for such a great plugin. My Indigo server is in one town and the Hue hub is in an apartment in another town. I have an ipsec tunnel between the two locations and the Hue Plugin works great.
Fyi, the debug output for the Cree bulb.
