So in OpenHAB you need to install the enocean binding by moving the appropriate .jar in the addons folder and configuring the config.
Reading the documentation for this binding ( EnOcean Binding · openhab/openhab1-addons Wiki · GitHub ) it seems that actuators are not supported, although that might have changed by now and merely the documentation not updated.
As noted in this post: EnOcean: what binding to use? there is another binding. I read a little about this a while ago, and if I remember correctly, this binding also supports actors. I haven’t tried that other binding out myself.
Good luck!
