Okay, new adapter received today and the buttons are connecting correctly in z2m! Now I’m trying to create the Things and Items necessary to make them work in OH3 and I’m struggling to understand the example provided here. Looking at the IKEA items at the bottom of the page, it seems fairly straightforward but I don’t understand where the SZMS and SZ in Thing topic SZMS "SZMS" @ "SZ" come from. Where can I find this in my z2m instance to make sure I’m using the right labels?
