Energy EAGLE Discussion

[nsheldon]

I'm running version 6.0.1, thanks for your help.

Okay. I'll check out the code and see what I can find that might be causing that. From the error, it looks like there's a non-ASCII character in the output from the EAGLE and it can't be interpreted properly. If you could turn on debug logging in the Energy EAGLE configuration while that error is repeating, then paste in the log into your reply, that would be helpful. The output will be big, but that's okay.

All right homeboy, here it is. If you need anything else, just say the word.

Version 0.9.7 Posted

Changes from 0.9.6:

• Significantly re-organized data gathering code by separating individual EAGLE command calls into separate methods.
• Changed status gathering back to every 5 seconds, but only for the current load data. Historical data is now gathered only every 20 seconds.
• Fixed a bug that would cause a UnicodeDecodeError by explicitly specifying that XML from the EAGLE is Windows-1252 encoded (as specified in the EAGLE XML-API docs).

Thanks richy. Those logs are helpful. The point at where it's crashing is where the debug logger is attempting to process the XML for display but runs into an encoding issue.

Try out version 0.9.7. I put some code in there to specify that XML data from the EAGLE should be interpreted as "Windows-1252" encoded (as described in Rainforest Automation's XML API). For some reason, your unit has a non-ASCII character in the output (perhaps a name or other custom parameter). Hopefully, this update will eliminate the errors.

[nsheldon]

Okay. We're getting closer. I think I know where that's happening. (That Meter Nickname is the culprit). I'll hunt that bug down and post another update later tonight or tomorrow.

I noticed that, but I can't find a place in the Eagle's UI to set the nickname.

Okay. Give version 0.9.8 a try. I don't know if it will work or not, but hopefully it will.

As for the meter nickname, I don't think you can set that on the EAGLE. I believe that information is provided by the meter itself (or, rather, the energy company who configures the meter).

OK! Thanks a lot Nathan for helping me get through those issues. The Energy Eagle is running like a champ now, and I am finally in the process of building my Control Pages, and including this information for all to see (and consider)!

I do have a recommendation, however. It would be really awesome if costs were rounded to two decimal places, instead of the 3 that are currently displayed. Aside from simply being a peeve, I'm not sure how I can spend $0.007 in real life without rounding up, so displaying it this way seems kinda odd to me.

Otherwise AWESOME PLUGIN SIR! Crap, even with the third decimal place, this is a super cool plugin that will really add value to my automation system. THANK YOU!

EDIT: I guess I could create a trigger that grabs this value, clips it, and injects the modified value into a variable or something. So in that case, never mind. If/when I get around to doing this, I'll post the code.

Sorry I forgot to get back to you on that one. So did that error clear up?

That's a good point. I'll update that to a 2-decimal-place value in the next update. It's not a difficult change, so if you don't mind waiting, there's no need to work on that trigger to clip the value and put it into a variable, unless you just feel like doing it.

Glad you like the plugin so far!

Nathan,

Forever ago, we were talking about how the Eagle represents negative net flow, since I have solar. You asked me for a snippet of the XML coming back from the Eagle.

The next day, SCE came out and replaced my meter, for no apparent reason, and it took 3 weeks (!) to get the meter provisioned and the Eagle to talk to it. Today, I finally had a chance to capture the data during the sunlight hours.

Here's what the Eagle is sending (for demand, summation, etc):

Code: Select all

 <InstantaneousDemand>
    <DeviceMacId>0xd8d5b90000000ea3</DeviceMacId>
    <MeterMacId>0x0007810000bfcf52</MeterMacId>
    <Demand>0xfffff88d</Demand>
    <TimeStamp>0x19d4ca0d</TimeStamp>
    <Multiplier>0x00000001</Multiplier>
    <Divisor>0x000003e8</Divisor>
    <DigitsRight>0x00000003</DigitsRight>
    <DigitsLeft>0x00000006</DigitsLeft>
    <SuppressLeadingZero>0x0001</SuppressLeadingZero>
  </InstantaneousDemand>

Note that the demand figure is huge:
demand = 4294965389
multiplier = 1
divisor = 1000

They've got negative numbers rolling over, so 0xffffffff = -1

Inverting it gives us what we need:

Code: Select all

>>> print (demand | ~0xffffffff)
>>> -1907

-1907 * 1 / 1000 = -1.907 kW (which is what displays on the web viewer)


For summation, we don't have to do this, because they are both positive numbers:

Code: Select all

		<SummationDelivered>
			0x00000000001341f2
		</SummationDelivered>
		<SummationReceived>
			0x00000000000313de
		</SummationReceived>

"Delivered" is energy delivered to the house from Edison (shown as "From Grid"), which I would call "Received", but whatever.

Hope this helps. Thanks!!
