We have had some reports that the SmartThings hub is not seeing the status of the Enerwave ZWN-RSM1S. We use this relay in our Z-Wave outdoor motion lighting products.
If this is true in your case, we recommend you visit this page and see if this fix, can fix the issue.
Please use at your own risk as we have no way to test this potential problem solver.
Let us know if it helped you as we would like to know to recommend it to others.
