[SOLVED] OSRAM Lightify Binding - Cannot write from sitemap into color

Hi!
using 2.3.0.201803021814 - with 2.3. snapshot

Items:
Color c_bulb “G10 Farbe” {channel = “osramlightify:rgbw:xx-xx-xx-x-x-x-xx-xx:color”}
(xx edited)

sitemap:

Colorpicker item=c_bulb label=“Color G10Farbe”

rules:
rule “c_bulb”
when
Item c_bulb received update
then
logInfo(“c_bulb”, "Update Received !! " + c_bulb.state.toString)
c_E10Bulb.postUpdate(c_bulb.state.toString)
end

In the logs, I can see the changes that I perform with the OSRAM app on my mobile.
Any change I perform via sitemap - or here in the example the value transfer to another bulb (c_e10Bulb) does not work.

Any idea why this is only a one direction communication?

Thanks
Michael
