Re: [mh] Whole House Power Meter

[David S. <dav...@ya...>]

Hi Joe,
Last week, I started to take a look at the "bad" ted packets to see if any could be salvaged. I've seen this behavior (replication of 0x10) that you describe. I've also seen "0"s get put in here and there. I'll add your code to TED.pm, run it for a while, and commit. I'll also add the other fields you found.

As far as my user code goes, all I am currently doing is logging KW usage and graphing it. I'm also attempting to graph hi/lo voltage, but I think I have a bug in my code. I'm actually away on business until Thu, so I won't be able to play mh until after that. At some point, I want to try to log dollars spent, as well as try to associate the wattage of the stuff I know about (lights,furnace,ac, pellet stove, etc), and try to get a breakdown by item of my carbon footprint.
Regards,
David Satterfield
