I’m going to have to run, but one last thought is that some devices only use S2 security and OH ZW only supports S0. Maybe that is also an issue (besides the duplicate communication). If you want S2 security you could look at this option. It requires MQTT, has S2 security. Zwave-JS-UI in place of OH Zwave binding - Tutorials & Examples / openHAB Stories - openHAB Community
