Modbus binding DI and AI config

It is connect to my modbus data thing indeed. To where should it be linked?

Btw, I really appreciate your help.

Donā€™t know then. Iā€™ve little idea how things should look in PaperUI.

The last log you showed us includes a TRACE for a discrete type register read, thereā€™s clearly more modbus Things defined than being shown here. Have you got duplicate Thing names somewhere? I donā€™t think itā€™s possible to do that without using xxx.things files though.

Where are you looking to decide your Item doesnā€™t show anything? Is there anything related in your events.log?

What I will do is, I will reinstall openhab on a clean ubuntu server and recreate only one AI. See what is does. There is not much in my current installation. Apart from my Denon receiver. My main goal is to get the PLC working, so I started with this. I will restart the whole install and setup process and let you know.
I will even configure it with xx.things files.

Ok, I got it working now.

I created an item using the follow option, not the default. I used it because I already created an tempsensor item to display the value. Now I used the default option and its working now. I can see te temperature now.
