But the integer conversion is not accepted: [WARN ] [nding.http.internal.HttpThingHandler] - Creating request for 'http://linhk.fritz.box:8000/pck?c=>M000005.R8M6%2$03d' failed: d != java.lang.String
Am I doing something wrong or is the conversion to string a must? If the latter, is there an easy way to pad zeros to a string?
All transformations return a String so if you’ve a command transformation then by the time you get to the commandExtension all you have is a String.
It’s not clear exactly what you are doing here so
What is the type of the Item?
What commands are sent to the Item?
What transformation is applied to the command?
Could you use a String Item with zero padded commands in the first place so no transformation or formatting is required in the first place? Maybe a Map transform to map what ever is sent to the Item to the zero padded number needed by the command extenstion.
The item is a Rollershutter type, so the command is a value designating the position of the rollershutter (I’m currently using a slider on the frontend). I also configured UP, DOWN and STOP but I wouldn’t need them if positioning through a value would work.
A string as return value of a transformation is exactly what I would expect as this is being appended to the URL. So my challenge is to cast a number between 0 and 100 to a string, eg. “027” or “004”.
