@Mieszko64Hi, If you have the Fibaro FGBS-002-2 Door-Windows sensor, the answer is no. 


To have the temp sensor DS18D20 working, I always use Smart Implant

    @Mieszko64You can connect up to 6 DS18B20 sensors to the smart implant. Look below.


    I've done this quite a few times trough the years.


    I always use: 

    Power Supply 12V 2A

    DS18D20 Sensors with 3m cable already assembled


    If you add or remove a sensor, you have to exclude/include smart implant again to the homecenter.


    Make sure you have stable connections between the smart implant and the sensors.
