Hello,
to add the temperature of my Fibaro Smoke Sensors I did the following:
1) Go to PulseStation Administration -> ImperiHome Service
2) Activate “Advanced Properties”
3) Add your device type in the box for DevTemperature (in my case the Fibaro Smoke Sensor is detected as “Routing Slave”, so I added “Routing Slave;”
After that and after restarting Imperihome and Zwave services I could add the temperature display in Imperihome.
good luck
Carlos
