Missing HMS 100 TFK Door / Window Reed Contact

I’m searching for cheap FS20 HMS 100 TFK door / window reed contact binding. There is no equivalent for this. HMS binding doesn’t support this.

FHEM implementation is:
https://wiki.fhem.de/wiki/HMS_100_TFK

Log is like this:
2006.11.06 19:50:38 4: HMS Device 5730 (HMS100TFK: Switch Detect: off)
2006.11.06 19:50:50 4: HMS Device 5730 (HMS100TFK: Switch Detect: on)

2006.11.06 19:52:36 4: HMS Device 5730 (HMS100TFK: Switch Detect: off)
2006.11.06 19:52:39 4: HMS Device 5730 (HMS100TFK: Switch Detect: on)
2006.11.06 19:52:52 4: HMS Device 5730 (HMS100TFK: Switch Detect: on)

The “on” and “off” is depending on NO or NC configuration.

Thank you but this is not helpful. My FS20 switches working fine but the HMS100TFK is some kind like HMS100TF.
This is the openHAB log:

openHAB bindings are interpreting the HMS100TFK wrong. There are no temperature or humidity sensors in this device, its just a contact and my old log in FHEM says “Switch Detect: off” or “Switch Detect: on”.

Is there a way to get the real values what is HMS100TFK sending?

I edited the topic and cut out the “FS20” term.
