For others with the same problem, I found the (a?) way to set up the FSR14:
Create a Thing and type in an EnOcean ID (must be 4 “Hex Bytes” and unique). In my case I chose “FFAA0001” and incremented for every thing (FFAA0002, FFAA0003, and so on).
After that, go to the “Channels” tab for this thing an add a Switch. All defaults should be ok here. Create the switch.
After that, in the Channels tab, set the checkbox “show advanced” in the top right corner. New channel options should be made visible.
Choose “Teach in” and link it to your just created switch. Save and open this new teach in item.
Now configure your FSR14 to learn mode. This depends on what you want to achieve. In my case I just wanted a simple on/off (Stromstoß, called “ES” within EnOcean or Eltako). So I
- moved the top configuration on the FSR14 to 5 (configures the next signal as ES switch)
- moved the bottom configuration to the channel on which the light is configured. I have a description from my electrician, which channel controls which light (1=kitchen, 2=living room, etc).
- moved the middle configuration to “LRN”
Now two LEDs should blink on your FSR14.
Activate the switch on your OpenHAB teach in item. The blinking should stop and this specific FSR14 channel can now be controlled with your newly created switch. Move the configuration wheels back to the position where you found them. (in my case from top to bottom: 0, auto, auto)
I don’t know if the teach in item can be deleted afterwards. To be sure I left them there and don’t deleted it.
As soon as I have the time I will also extend the OpenHAB EnOcean documentation.
