Debugging / Triggering Smartthings Rule for channel event

I am using Bobrak’s Samsung Smartthings Binding (org.openhab.binding.smartthings)

Have a Bosch motion detector. Event log shows the following ’ Smartthings updated State for channel: smartthings:motionSensor:Home:Sensor1:motion to inactive’

But when I try to trigger a rule based on the channel event it never triggers. Not sure how to trigger a rule as seen per channel update listed above. I have tried the following without succes. What am I a missing ?

Here’s a snapshot of the log

2018-11-03 13:44:31.675 [INFO ] [ings.handler.SmartthingsThingHandler] - Smartthings updated State for channel: smartthings:motionSensor:Home:Sensor1:motion to active

then
   logInfo(logfile, "MotionRule triggerd---------------------- ")
   Plus_TTS.sendCommand("Boooo")
   sendCommand(OfficeLight5_Toggle, OFF)
end

Looking through the README it appears that you must link the Channel to an Item. Channel triggers are something that must be implemented by the binding and if he had implemented that he would/should have provided documentation for how to use i in the README.
