FHT docu mistake

[dartrax]

https://www.openhab.org/addons/bindings/fht1/ :

FHT is a range of devices produced by busware.de which allows to interact with various protocols and devices over radio frequencies. It's also possible to build one on your own.

Original Manufacturer: http://busware.de
Build your own (German) http://www.fhemwiki.de/wiki/Selbstbau_CUL

FHT is not produced by busware.de and is not the topic of the Build your own link. It should be CUL, not FHT. CUL is a transceiver for communication with FHT (among other protocols).
