After upgrading to OH3.1 the ikea blinds give error when receding command DOWN.
The command UP works ad normal.


15:44:01.639 [WARN ] [ternal.handler.DeconzBaseThingHandler] - Sending command DOWN to channel deconz:windowcovering:0d07c85bd3:000d6ffffe90464201:position failed: class java.util.concurrent.CompletionException - java.util.concurrent.TimeoutException: Total timeout 2000 ms elapsed

Have tested with 3.1.0.M3 and latest https://openhab.jfrog.io/artifactory/libs-pullrequest-local/org/openhab/addons/bundles/org.openhab.binding.deconz/3.1.0-SNAPSHOT/org.openhab.binding.deconz-3.1.0-SNAPSHOT.jar
But same error.

When downgrade the binding to 3.0 it works fine.
