@olaeke : Thanks! So in total four devices meaning, the Node itself and a device for every (Child)-Sensor. Makes sense. Just wondering what other Controllers are doing here. I think at least some completely ignore the child node numbering and either put all values without context or all values under the Node.

@daulagari said: that makes sense although not from an user perspective Of coarse not. I just wanted to sketch the idea behind it.

Tried again with Firefox and now things are working. Problems solved!
