Link config - auto - issue

Hello, there.
Link items’ mode - auto. I’m adding 2 different devices via PaperUI.
1st device - item is not linked automaticly.
2nd device - item is linked automaticly.

Why so? It’s not guaranteed the items will be linked automaticly?

What devices? What bindings?

Sorry. This are ZWave devices and binding.
Dimmer’s item is linked automaticly.
Switch’s item is not linked automaticly.

Sorry, closed. It was paperUI issue. When mode is auto - no item created after thing adding. It’s added after you click on channel radio button.
