Current Cost and EDF EcoManager RF protocols almost fully decoded

Thanks to the enormous help of Graham Murphy, Matt Thorpe and Paul Cooper, the wiki pages for the EDF EcoManager RF protocol and the Current Cost RF protocol are nearing completion. Of course, jump in if you have anything to add. Anyone with a github account can contribute.

And my EDF EcoManager C++ AVR code is ticking along. Still some distance from being usable "in the field" but getting there.

One quick random thought: for those of us who have been tinkering with the Current Cost RF protocol, it appeared rather odd that the data is "manchesterised". It occurred to me this afternoon that we can take advantage of this structure in the data to validate the data. A little more discussion on the wiki.

UPDATE 30/10/2012

Current Cost have asked me to remove the protocol documentation from the wiki. More details here.

UPDATE 5/1/2016

Current cost have kindly allowed me to put the docs back onto the github wiki!

EDF EcoManager wiki

I've started a wiki page for technical details of the EDF EcoManager protocol. Please feel free to edit!

Success pinging EDF IAM and receiving response.

EDF IAM with NanaodeEDF IAM with Nanaode

Yesterday my first EDF Individual Appliance Monitor arrived. These are very, very similar to Current Cost IAMs except for several vital differences:

  1. Each EDF IAM can both send and receive (the CC IAMs can only send).
  2. Each EDF IAM will only report its wattage when polled by the EDF EcoManager base station. This is great for my application because I should be able to completely avoid RF collisions.
  3. Each EDF IAM also has a relay to turn the appliance on or off. This relay can be activated using the manual override switch on the EDF IAM or over RF
  4. The packets appear to include a simple checksum! (The CC Transmitters don't bother with a checksum.)

I've made good progress today. I think I can now reliably talk to my EDF IAM and get replies.
