So back to the AEON ZW078
Found this on it: Z-Wave JS Config DB Browser
And this: https://products.z-wavealliance.org/products/998?selectedFrequencyId=2
Based on that info it appears it should work with my standard plugs driver (not the mcp). The on/off commands are very standard so not sure why it would not even respond to that. I am using the switchBinary z-wave commands and the z-wave alliance info says it supports that command class. Power metering should work as well since it is very standardized in Z-wave, but may not show up right away until it sends a report.
Its an older device, so my scanner tool I do not think would be able to pick up on the settings for it.
The only possible issue I see if that it uses the Hail command class but that would only come into play if you manually turn it on/off via a physical button on it.
Anyway... if you really want to get it working with power metering I am sure we could make it work.
If anything, use the settings guide I gave above to minimize or disable the power reporting if you are not using it. It would cut down some traffic. You can use my scanner tool to manually set the settings, or the "Basic Z-Wave Tool" code from HE that can be found on the forums.
