Just ordered an Efergy E2 Energy monitor for the mains in the house since Ergy’s historical analysis seems to have gone down the tubes on 1.5.322. This gathers information and reports it to the wireless display. It is a very reasonable cost and has basic historical data capabilities. It uses USB to periodically dump the data to a PC. Can anyone give me any hints on interfacing it via the usb to vera. The company is willing to share information regarding this.

Thanks folks!

If you know how to do scripting you could probably adapt one of the existing plugins (CurrentCost, TED5000, or Brultech) to talk to the new prototol that the Efergy supports - esp since they’re willing to give you the protocol docs.

Source for these is over on http://code.mios.com

Thanks, It also broadcasts on 433mhz but I will follow up on that later. Currentcost seems like a good starting point to add LUA to my inventory of coding languages. Started in 1962 and every year there is more. Love the names that are dreamt up for them. First program was written in machine language.

Cool… Started in '79 with BASIC, my second was hand-converted Assembler/Machine code (to speed up BASIC), so I understand where you’re coming from, albeit slightly later in timeline. :wink:

Since then I’ve lost track…

Good luck on the adventure. It should be fairly simple to pickup given your background and the CC example (thanks to @futzle)

Is there any progress with getting data from Efergy to Vera?
Did you get any info from the company regarding the communications protocol?
I’m considering getting the Efergy E2 Elink, and I’m trying to figure out if it supports constant data reporting via USB.
