In my experience the odds strongly favor a network communication issue that could be uncovered with a Zniffer. However, the network health function of the PC controller might help. Here is an earlier version of mine (green means good communication) ![Zooz ZST10 network stable](https://community-openhab-org.s3.dualstack.eu-central-1.amazonaws.com/original/3X/3/9/3946ab22bbe8a9b0da89b637c32667f50a70779a.png) However, one question I haven’t asked (and I don’t see in your posts) is what are you running OH3 on? There is a known issue with some early versions of the Aeotec Zstick with a Rpi4 that requires using a USB hub (doesn’t have to be powered) between the Rpi and the stick. I don’t have that issue, but use a powered hub for the zstick anyway, so the zwave radio is always getting steady power, rather than rely on the Rpi power. I find that helps communication. Lastly, you might want to review this [post](https://community.openhab.org/t/solved-unresponsive-z-wave-network-tools-and-approaches-to-track-down-the-issues/122446) for other ideas.
