Hi everybody,
I have the following setup:
- Raspberry pi
- Waveshare RS485 adapter - http://www.wvshare.com/product/RS485-Board-3.3V.htm
- various wired Homematic devices
- HomeGear
- OpenHAB
The RS485 module described in Homegear documentation (https://www.homegear.eu/index.php/RS485_Serial_Module) has two separate pins for “driver enable” and “receiver enable” however my module has only one pin described as RSE.
I have tried all the combinations of setup in physical interfaces.conf to make it work but no luck. When I try to search for the devices on the bus, the log is full of errors:

Seems like there is a problem switching RX / TX mode. When I create an event on the RS485 bus (pushing the button which is connected to RS485 Homematic module) it is somehow detected by Homegear, but…

Can this Waveshare module be used with Homegear? How should it be configured in physical interfaces.conf? Please help, I’ve already spent many hours trying 
Wireless BidCos devices are working fine with the CUL stick.
Thank you very much
