I have a sensative strips contact sensor that was paired to smartthings. It worked perfectly. I successfully excluded it from smartthings. I verified in smartthings that it was excluded.
I then included it to HE. ,According to the logs, the device was successfully included. The sensor is listed in my HE devices. It reports that the battery is at 80%, which is what is what it was formerly reporting under smartthings. However, it is not reporting closed or open. When I click on the device in the device list, it shows battery: 80%, but nothing about contact.
I repaired the z-wave network, and I rebooted my hub, but no luck.
Strips multi-sensor is a light/water/Temperature sensor so it shouldn't be used with the strips contact sensor.
I've used the strips contact sensor with the generic contact sensor driver and it worked fine. I believe others on the forum have confirmed the same thing.
Enable debug logging, open logging, and see if anything gets logged when you trigger the sensor.
Have you tried rebooting the hub? I just noticed a probably-unrelated-but-similar thread about iris contacts that didn't start reporting open-close until a hub reboot.
