OH3 - Polling FGT-001 on Z-Wave, but the Items are not updated

I recently upgraded from OH2, but I did not migrate anything, I set up everything from scratch.
In OH2 I had 1 Hour polling of my FGT-001s (5 pieces of Fibaro Heat controllers), and it worked like a charm.

Now it does not.
The items are not updating, even though I am using the same setup.
It seems that polling works, somewhat - see the Z-Wave logs below. At least I receive temperature updates (nothing else though, like battery, etc), but the linked items are not updated - values remain the same, and there’s no corresponding entry in the events.log.

If I re-initialize a device, or my Aeotec Z-Stick, only then I get new values.

Any ideas?
I set up the Items based on the Things, if that matters.
