Re: Power monitor for NEMA L5-20?

Watts-up.  I have the network connected one.  Very handy little tool.

It'll also reboot if you want it to.

I'm not aware of a 20a unit though.  You'll have to call them about that. 
(NOTE: Not everything that they make seems to show up on the web site.)

laters,
