I had all my Zwave devices controllable via the floorplan up until I added an event handler to my living room lights. Now my family room lights disappeared from the floorplan. When i go to the floorplan in pluto-admin, the family room device is not even listed, so i can't just drag and drop it back on the floorplan. nothing was deleted, only an event was added. All devices are still controllable by the autogenerated on/off scenarios, but do not show up on the floorplan anymore. By the way, i swapped out the old zwave driver to see if it would solve the issue. What took place and how do i fix it?
