I have a FGBS-001 with a 1-Wire temperature sensor connected to Openhab2 using z-wave binding 2.2.0.201712022337.
Openhab reports the temperature with a value in the range of 170 at room temperature. When I connect additional sensor both read the same value in the range of 170. (Additional Sensor added as per Fibaro instructions.)
The log console shows the following "NODE 10: Received a multi instance encapsulation with a destination endpoint = 3. " for each temperature update.

The DS18b20 Temperature sensors were set 9 bit resolution, they need to be set to 12 bit resolution. To change the resolution I followed the guide here. It uses an Arduino to write the resolution to 12 bit in the eeprom.
