Make sure you are on the latest version of the custom TS004F driver.
Then, enable the 'Advanced options', refresh the Preferences tab and toggle the 'Respond to ZDO requests' option ON :
Save the preferences.
Then, obligatory, use the Double Luck Voodoo to pair the device again to your C-8 hub (do NOT remove the device).
If the pairing process is successful, the flashing scene switch LEDs should start flickering quickly after a few seconds and then the four LEDs should turn off.
