Hi, i’m pretty new to openhab, have a EIB/KNX bus connected and would like to add Blauberg devices :-), anything availible ? here the wep page [http://blaubergventilatoren.de/en/series/vento-expert-a50-1-pro](http://blaubergventilatoren.de/en/series/vento-expert-a50-1-pro) The Units are connected via W-Lan and can be controlled via UDP Protocol description is here [http://blaubergventilatoren.de/uploads/download/ventoexpertduowsmarthousev11en2.pdf](http://blaubergventilatoren.de/uploads/download/ventoexpertduowsmarthousev11en2.pdf) Thanks Thomas ---

There is the TCP/UDP Binding. It isn’t super easy to work with but in this case you at least have a published API and don’t have to reverse engineer it. ---

Thanks Rich, is there a new binding for TCP/UDP binding for OH2 ? thanks Thomas ---

No. There is only the 1.x version. ---

Hi Thomas! I have programmed two Python scripts which together monitor and control the Blauberg Vento Expert wifi fans as well as Vents Twinfresh Expert Wifi fans by using the MQTT protocol. These scripts are avilable in my netshop: [http://bit.do/exscg](http://bit.do/exscg) or [https://blomkvistitk-no.loopiasecure.com/produkt/fan2mqtt-mqtt2fan-licenses/?lang=en](https://blomkvistitk-no.loopiasecure.com/produkt/fan2mqtt-mqtt2fan-licenses/?lang=en) Regards Roger ---

Hi Thomas! Did you manage to connect Blauberg vent with UDP binding? If you did, could you share the code? ---
