I had added a number of Things with the Paper UI: 1 with the network binding and another 4 or 5 with the Zwave.
Today, thanks to a couple of power cuts meant the raspberry pi was restarted a couple of times.
This evening something is not right (my shutters didn’t close), and I discover all Things have disappeared. Not one of them left. The bindings I had added are still there. The rules, items, and sitemaps defined in files still exist. But nothing works anymore because all the Things have disappeared.
Can anyone guess how this could happen? Was there some update that could have wiped the database?
