Nspanel86pb did not update the thermostat widget from a existing group (TRVZB)

Is there a chance to view the settings from a TRVZB group if i change the temp-settings on the TRVZB.
also it is not possible to set the SNZB-02D temp sensor in the group-widget for viewing the temperature
3 TRVZB and the sensor are in the same room in ewelink.
