Does not detect notification when app sends a notification

I am new to tasker so please help me if i missed a step to get this work. 

bassicaly im trying to get tasker to detect the notification from one of my app and to perform a task to play media. 

My idea is once my door is open, my door sensor triggers and send a notification to my tablet. once tasker reads the notification about door sensor it must play a voice recorded. 

i have successfully uploaded my media play in task tab but my profile is not detecting the notification from my smart app in order to play the media. 

Please help me with this?

thanks
