I have an Ikea trådfri gateway, and I connect it to openhab using the binding - everything works as it shall and the gateway thing states online, and I can add things for my connected bulbs. However, after I reboot the gateway there are no trådfri things anymore, and I can find the trådfri gateway in the inbox in paper. I just upgraded to the latest stable version of Openhab, but the things still disapears on reboot.
