HMIP BBL - Horizontal tilt not working
Hi guys,
first of all: Great Job! I really enjoy using the Homamatic devices in Homekit.
Unfortunately, I have an issue with my HMIP BBL Devices. I can move them up and down but cannot set the horizontal tilt position.
When opening the settings on Homekit I can see there is a slider, but shortly after moving the slider I get the "no response" error message on that corresponding blind.

My configuration:
{
            "name": "HomeMatic CCU",
            "ccu_ip": "192.168.178.49",
            "subsection": "Homekit",
            "enable_hmip": true,
            "enable_wired": false,
            "ios10": true,
            "services": [
                {
                    "type": "HmIP-BBL:BLIND_VIRTUAL_RECEIVER",
                    "service": "HomeMaticHomeKitBlindSlatServiceIP"
                }
            ],
            "platform": "HomeMatic"
        },

The shutter devices I use:

**Which Homematic Device or Service the bug is about**

This is my CCU3 config for one of the blinds.
