Hi Don,
From the email response I just sent:
ON/OFF commands for voice control is based on status. So, if MobiLinc has an ON status for a device/scene, it will issue the OFF command. If MobiLinc has OFF for the device/scene status MobiLinc will issue the ON command. The how's and why's of this is on our voice control website (see below).
If the devices in MobiLinc aren't getting status, then that indicates that one or more of the devices MobiLinc can't reach through the SmartLinc. Watch device status roll in and see if MobiLinc gets stuck on a device for more than 10 seconds. That’s where you should focus to determine why the communication to that device is less than desired.
