Sorry. no, I use don’t use nodered or the emonSD/emonPi image I’m at a loss on that front.
However I do have some of the TP-Link HS110 smartplugs same device but with in-built monitoring that I have a draft Python script for that posts to an emonhub socket that I intend to develop into an emohub interfacer, so at somepoint in the not so distant future we may see this functionality available in emonhub, although it would also have been nice to see this Wifi Meter plugs out of the box (Z-WAVE or others) discussion result in a emoncms module.
