Do i make a mistake or is it a bug?
Thank for your reply

What channels show in the Paper UI ? switch may not be a valid channel name for that device.

If i validate Items linking in Paper UI then créate things and items, the item is not vosoble in Paper UI.
and in Habmin UI the créate thing has no canaux in configuration

Please read about openHAB concepts.
1, Discover / create Thing , usually having many channels
2. Create Item
3; Link Item to a Thing/Channel combination

You cannot have items linking before Things and Items are created.

Sorry, my explaination is not clear. I do like you explain and there is no channel.
For information my openhab installation are 3 years old whith about 100 items ans on this Somfy Tahome about 20 working items. Only this 2 items are not working.

This will start explaining the concepts better than I can do here.

See Tahoma Binding compatible with OH2 for solution
Bye
