I think 16 devices. All mains.

All mostly at the controller end of the house, I have started putting devices at the out reaches.

No sniffer just the si labs pc controller. Can that tell me routing? I know it can set routes, but the doco is a little sparse on how to do this, and what it should look like.

Not brick, Just timber, dry wall ( I think that’s what you call gib board in the us)

I’d posted this similar topic with a node made and floor plan: [Zwave node - weird neighbours](https://community.openhab.org/t/zwave-node-weird-neighbours/100474)

Node 19 is on the 2nd floor, Probably close to the node 7 which is in the little room at the bottom of the floor plan.

Generally the zwave has been good, but adding this last node has caused me no end of problems. It was generally working, and responding, but has since stopped.
