Z-wave items receive update every 30min #23

Hi, this might not be related to the nodes, but I figured I should ask, as it might be related somehow.

I have a simple openhab-get on a item that logs when item receives a raw command. And it works fine, except that every 30min items receive an update like 21.01. 07:55:22: Ack: TestZwave_Switch changed to ON 21.01. 07:55:23: Ack: FilCameraWall_Switch changed to ON 21.01. 08:25:22: Ack: TestZwave_Switch changed to ON 21.01. 08:25:23: Ack: FilCameraWall_Switch changed to ON 21.01. 08:55:22: Ack: TestZwave_Switch changed to ON 21.01. 08:55:23: Ack: FilCameraWall_Switch changed to ON

I do not have mentioned items anywhere in rules nor flows, and strange thing is that this only happens for z-wave items. Not for virtual items, and not for ikea lights for example. This makes me think that command comes from openhab side. However, no such events appear in openhab logs, only on node-red side.

I wrote similar topic to the openhab forum https://community.openhab.org/t/z-wave-sends-command-to-items-every-30min-even-if-no-change-on-item/39028

So I am unsure, is there some timer thing on the node-red side that checks on items state perhaps?

This can be closed, as it is expected behavior of the z-wave binding (explained on the linked forum topic)
