Newbie Question about Linear zwave GD00Z-4 Garage Door Opener

I have wired up the GD00Z-4 opener with ST and my garage door opener. I am using the tilt sensor that came with the linear device. The ios app detected the device and I added to the hub. However, the status shown is unknown, what am I missing ? I am a newbie in this IOT and would appreciate if someone can show me the steps to get it to work properly. I am looking something basic such as open/close status/control with notification. Thanks.

Open and close the door once or twice and the linear device will catch up.

Thanks Gary,

I have tried open/close several times initially but the status remains unknown, but after I re-seated the sensor battery, deleted the initial apps when I configured the device and open/close the door several times then the status finally show up.
