See if this "fix" works:
In the device driver (MyQ Garage Door Opener), line 130 is currently commented out:
// updateDeviceStatus("closing") // Now handled in the parent (in case we have an Acceleration sensor, we can handle "waiting" state)
Change this to:
updateDeviceStatus("closing") // Now handled in the parent (in case we have an Acceleration sensor, we can handle "waiting" state)
i.e. uncomment "updateDeviceStatus("closing")
I think that should fix it, but I'm at work, so I haven't tried it.
