Mqtt Binding: step property nor working properly for transformations

Thanks for your help.
But there is no call for the scripts in the Things file?! I am currently running Oh2.5 M4

Did you try using the example above and placing the scripts (three separate .js files) in /etc/openhab2/transform?

Hi,

I tried the files getZigbeeBrightness.js and setZigbeeBrightness.js like described here

Dimmer Ikea_Lampe_1_Dimmer “Dimmer” {channel=“mqtt:topic:ikeabulb:BulbDimmer” [profile=“transform:JS”, function=“getZigbeeBrightness.js”, sourceFormat="%d"]}

But it will not work. I’m not shure if the function is called
is there a way to debug it?
Or is there another way to call the functions?

Transform profiles currently only work on String type Items, not Dimmers.
