Exhuming this thread: My RAVEn arrived the other day (from Fastnetworks) and it's now hooked up to a Raspberry Pi. Interestingly, the Rainforest Automation site no longer references the RAVEn at all, but I think Gordon at Fastnetworks will still have a few. I'm in a Powercor area. I was able to log in via the portal and once I'd registered the meter via the ID on a power bill, I was able to enter the Raven's MAC and another key from the device, at which point the meter and the RAVEn were paired and data began to flow. I'm using a script based on the one Ashley mentioned ( https://github.com/frankp/python-raven/blob/master/raven_script.py) I'm just getting my head around what data is produced, but it's all there and all available. Having solar panels on the roof causes out Instantaneous Demand figure to get really thrown out of whack, so I still have some hacking to do before I get a set of figures I'm happy enough to rely on. Good for exercising the very rusty Python skills ! I'll also happily receive pointers to any existing wheels so I am not re-inventing them ! Ultimately I plan to feed figures into RRDtool or similar to produce graphs. It is interesting how sensitive the readings are. I had it running and tailing the log file last night and it was quite easy to see the effects of turning lights, the TV and electric kettle on and off.
