I have forked [GitHub - Signalare/com.se.wiserapp: Schneider Electric Wiser](https://github.com/Signalare/com.se.wiserapp) to try to add the Shutter puck.  
I have got the blind running but now I need to calibrate it so it can be set in a specific %.  
In the wiser app you add the number of seconds it will run when you do this.

These are the attributes after interviewing the Zigbee device

```auto

                  "direction": "reported"
                }
              },
              {
                "acl": [
                  "readable",
                  "reportable"
                ],

                "reportingConfiguration": {
                  "status": "NOT_FOUND",
                  "direction": "reported"
                }
              }
            ],

```

This is the code right now which I have tried that doesn’t really work for setting the correct position but does make it move:

```auto
// Register windowcoverings set capability and configure attribute reporting
        this.registerCapability('windowcoverings_set', CLUSTER.WINDOW_COVERING, {
            setParser(setValue) {
                // Apply calibration factor to convert setValue to the appropriate range
                const calibratedValue = (0.87 / setValue);

                return calibratedValue;
            },
        });

```

It is the attribute currentPositionLiftPercentage that needs to be set correct.  
If I do it manually it shows 13 when it is maximum open and 0 when closed. When the code runs it ends up att 255 which seems to be max for the driver.

Any one that has an idea on how to accomplish that?
