@sihui
thanks for answer and good tip

in paperui all things are created and checked but there is no thing in the folder /etc/openhab2/things
is this a ordinary behavior?
where save paperui this things?
just for info:
I have imported all things and doing a restart
after restart all things still there
so i don’t no what happen yesterday and why the things was lost
