# Rollershutter Position Emulation Profile Service
|
|
|
|
The Rollershutter Position emulates absolute position setting for Rollershutter devices which only support basic UP/DOWN/STOP commands.
|
|
This allows a Rollershutter to be set to an absolution position from 0..100 even if the controller does not support this feature (i.e. Somfy controllers).
|
|
|
|
The logic code used for this profile service was adapted from Tarag Gautier's JavaScript implementation VASRollershutter.js.
|
|
By implementing as a profile, it eliminates the need for setting up a jsr233 js environment and simplifies the configuration.
|
|
|
|
## Configuration
|
|
|
|
To use this profile, simply include the profile on the Rollershutter item which is assigned to the Rollershutter channel.
|
|
The parameters <uptime> and <downtime> are the time it takes for the Rollershutter to fully extend or close in seconds.
|
|
The precision parameter can be used to specify the minimum movement that can be made.
|
|
This is useful when latencies in the system limit prevent very small movements and will reduce the accuracy of the position estimation.
|
|
|
|
```java
|
|
Rollershutter <itemName> { channel="<channelUID>"[profile="transform:ROLLERSHUTTERPOSITION", uptime=<uptime>, downtime=<downtime>, precision=<minimun percent movement>]}
|
|
```
