Has anyone already put the sensor into operation as a pure Z-Wave thermometer? Without using an associated radiator thermostat? On the one hand, there are corresponding Z-Wave pages (e.g. https://manual.zwave.eu/backend/make.php?lang=en&sku=FIBEFGBRS-001&cert=), on the other hand, according to the instructions, the thermometer is coupled with the thermostat.
