Unknown Device Eurotronics Comet Thermostat Z-wave

Hi All,

i’m new with openhab on a Raspberry Pi3. Some ÄThings i could manage, but the Thermostat is still a unknown device. How can i make this workable?
Many Thanks.
Tom

Trigger NIF a few Times. There is a Small Button inside the battery compartment. Short click it a few times.
