I tried to discover a Monoprice branded Z-Wave power switch with "Amazon Echo Skill", but it did not work. In the logs I saw the following message:
2019-01-06 19:25:28.131 errorjava.lang.NullPointerException: Cannot invoke method toLong() on null object (updated)
When I use the legacy "Amazon Echo App", device is discovered properly. Happy to collect more logs, but would need instructions as to how to enable and capture them.
