How to write Parameter on Master using Homematic Binding

Hi!

Thanks for your answer! Okay, I was hoping you would say that this is possible :wink:
Fortunately, I now found another way to achieve what I want: I made Homegear available via MQTT and now set the value via MQTT (how to do this is documented here).

For anybody also stumbling on this problem, this is my configuaration (using the OpenHAB 1.x MQTT binding):

Item:

Switch bathroom_SHOW_HUMIDITY "Show humidity" <humidity> {mqtt=">[default:homegear/default/config/19/0/MASTER:command:*:MAP(switchhumidity.map)]", forceUpdate="true"}

Transformation file (switchhumidity.map)

ON={"SHOW_HUMIDITY": 1}
OFF={"SHOW_HUMIDITY": 0}

It only works in writing mode, reading out the current value is not possible as far as I know, but it is a good starting point!
