I have the ST hub 2 and have been using this successfully for a week with ST sensors.
I have just added to the hub two Fibaro Door / Window sensors which now appear in the App. Both of these sensors show contacts closed permanently. They are activated by the magnet (blue light flashes) and the TMP button also activates the blue light flashing. In the App nothing changes so it appears that the ST hub is not detecting the open / close event.
I have followed the exclusion process in the Z wave utilities area but this does not improve things.
