The errors that you are seeing are only related to the shutdown of the controller - so should not affect the initialisation. I will take a look, but it shouldn’t impact using multiple controllers.
Hi Chris @chris
Since this, I’ve factory reset the controller and the nano dimmer 2 from aeotec. The controller shows up as Online under ACM0 or 1.
It did find the Node, Node 2. And it was online but since has gone offline.
The Controller and Node are about 1.5meters apart.
If you have factory reset it, then it will no longer be in the network and will need to be reincluded.
Yes I’m aware of that 
I obviously re-included it for it to be present in PaperUI, but it remains off. For some odd reason.
Is your OH setup in a docker? I read that remote zwave controllers may not been seen if your OH is inside a docker setup
