The issue is that the blinds in question were added earlier this year and the ZWave DB hasn’t been upgraded with the OH4.3 patch releases. Only devices since 12/2024. You can use this procedure to update your current binding or take the plunge to OH5.0M2 (64 bit OS, Java 21)

Note that the ZW log viewer only reads Debug logs. Is that your binding setting when running your tests? The switch should be fine with debug output. Is it?
