Currently, INSTEON only supplies a single lock controller.
The MorningLinc controller uses RF to control locks and deadbolts from Morning Industries. Because the RF communication is one-way, there is no status presented from the lock to the MorningLinc, so Indigo can't know the status of the lock (locked or unlocked).
The controller has an additional INSTEON security feature which requires special linking steps. Specifically, you must use the technique of holding the MorningLinc's SET button when defining it and not try entering the INSTEON address directly into Indigo, and you must perform the Define and Sync process in Indigo twice as detailed below.
To define the MorningLinc device in Indigo for the Locked (Turn On) Command:
File→New Device…
menu item to create a new Indigo device.Define and Sync…
button inside the device dialog.Start
button.Next we need to re-Define and Sync the module again for the Unlocked (Turn Off) Command:
Define and Sync…
button inside the device dialog.Start
button.Once this is completed you should be able to both lock and unlock the device by using the Turn On and Turn Off buttons in the UI. If locking works but unlocking fails then repeat the last section of steps above.
