What functionality is the Z-Wave command class [tt]COMMAND_CLASS_POWERLEVEL[/tt] supposed to provide?
Does Vera support [tt]COMMAND_CLASS_POWERLEVEL[/tt]?
Not sure if anyone is still reading on this post, but I had the same query. I have a Jasco switch that has this Class listed. Can it read power?
I found the fundamental level source code documentation at
http://open-zwave.googlecode.com/svn-history/r185/trunk/cpp/src/command_classes/Powerlevel.h
which has the look of ‘sound levels’ – guessing at the dB indicators are decibels, but who knows.
In any event, let me know if you got a better grip on this command class’s particulars.

I thought it was for test/optimization purposes, to test communication links between nodes (by altering their transmit power).

Hmmm, yes, I gather that looks like internal network power setting (can’t read the code too well and a bit sparse on comments).
Just to widen this thread a bit, is it a fair to say that any proper power metering will only be available with devices that have COMMAND_CLASS_METER in their device capabilities statement? Leaving aside perhaps COMMAND_CLASS_METER_PULSE, which I presume is used for pulse-type readers on external ‘dial type’ electricity meters?
