I´m currently testing openhab 2 and trying to setup my devices including homematic. I have several homematic wall mounted thermostats, heating thermostats and window contacts. They are organized within an internal group (INT0000001…8). In openhab 1, I could add those groups e.g. for setting the temperature. However, in openhab 2, these groups are not discovered as things.
Is there any way to use them? Especially in setting the temperature, using these groups works far more reliable than sending a new temperature to a single device of the group.
