Matplotlib Plugin for Indigo 7 - New!

Ok. I'm here to help if I can.

Ok. I'm here to help if I can.

Thanks, but I found it. Totally my bad. The short version of the story is that I introduced a bug in the key assignment routine and, as a result, was working with strings instead of integers.

Code: Select all

>>> a = '2'
>>> b = '10'
>>> print b > a
False
>>>

I have fashioned a fix and will test it on my production server when I get home from work. Tests on my development server (which I have with me always! ) are working as expected. Sorry for the trouble. Please hang tight with 10 charts for a short while longer.

Durosity refers to it as 'incompetence' and I agree with him in this case.

I have posted an update to the plugin that should address known issues. Please let me know if there are others. All future plugin updates will be announced on that thread.

Tried this last night and had some real trouble. The low hanging fruit is my lack of clear understanding about what the "State" is, and what can be put there.

I'm trying to chart output from my Aeon Smart Energy Meter, and it has a tab called Meter Total. But when I put that in, I get a Matplotlib error in the log referring to being unable to find such a thing.

Code: Select all

Invalid CSV definition. 'key Meter Total not found in dict'

This is just the first of many things I'm apparently not understanding about how to configure this plugin.

Code: Select all

Matplotlib Warning   Invalid Indigo ID. invalid literal for int() with base 10: 'None'
Matplotlib Critical Error   Energy Line Chart: Check path to CSV file (max() arg is an empty sequence)

All help appreciated!

Have a problem when trying to run an Action Group to Redraw Charts with the following error in log:

Code: Select all

   Action Group                    Odśwież wykresy Mathplotlib
   Matplotlib Error                Error in plugin execution ExecuteAction:

Traceback (most recent call last):

For the CSV engine, there are three pieces of information that you need for each data element. A title, a source and a value. The title can effectively be whatever you want (there few small exceptions). The source, as you've probably figured out is either a device or variable ID. The value is either a device state or a variable value. For variables, just enter the word 'value'. For devices, it has to be a defined state for the device you're using. The easiest way to see them for any device is to run this Python script in Indigo:

Code: Select all

indigo.server.log(unicode(indigo.devices[DEVICE_ID].states))

Copy the device state name exactly and don't use the ones that have '.ui' on the end. Of course, you can only use things that are chartable (numbers not words, etc.)

You might find it helpful to open TextEdit to use as a scratchpad.

Have a problem when trying to run an Action Group to Redraw Charts with the following error in log:

Code: Select all

   Action Group                    Odśwież wykresy Mathplotlib
   Matplotlib Error                Error in plugin execution ExecuteAction:

Traceback (most recent call last):
  File "plugin.py", line 984, in refreshTheChartsAction
TypeError: 'PluginAction' object is not iterable

Darned if it doesn't.

I've identified the offending code and, embarrassingly, it's a simple piece of code that's supposed to write something to the log. It's now fixed and will be included in the next update.

Thanks for reporting it.

Thanks very much Dave. The update is working perfectly well for me after adding 14 elements. On a side note, what was raised by different Computers above is a good point I think. I also spent some time trying to figure out what state means, entering text like temperature, for example. I know it is obvious for you, as it is for me now, but at the very beginning maybe including a line in the description will certainly help (at least for some of us). It could be just to execute the phyton command you suggested at the beginning of this blog to obtain the correct answer.

Glad to hear that solved the issue for you.

I agree that the CSV engine is a bit wonkish and I'll add something to the initial post with that as a tip. I'm looking at ways to simplify the way that elements are added, but want to be sure that I don't make it even more difficult to understand.

indigo.server.log(unicode(indigo.devices[DEVICE_ID].states))

Sorry, " run this Python script in Indigo" doesn't work as:

A. pasted in the scripting shell
B. embedded python in an action group.
or, outside of indigo in a python prompt in Terminal.

WHERE do I run it in Indigo?

It runs fine - the output is in the Event Log window. Looks something like this:

Code: Select all

Did you substitute DEVICE_ID with the actual ID of the device?

Did you substitute DEVICE_ID with the actual ID of the device?

ahhhhhhhhhh.

See, I thought it was a variable.

Duh.

I get this:

Code: Select all

     accumEnergyTimeDelta : 73962 (integer)
     accumEnergyTimeDelta.ui : 73962 seconds (string)
     accumEnergyTotal : 0 (real)
     accumEnergyTotal.ui : 0.0 kWh (string)
     batteryLevel : 36 (integer)
     batteryLevel.ui : 36% (string)
     curEnergyLevel : 1301.08 (real)
     curEnergyLevel.ui : 1301.080 W (string)

thought I was looking for something like a device ID. Should I use curEnergyLevel or curEnergyLevel.ui? I'll experiment.

re-enabled Matplotlib and my log fills with red:

Code: Select all

Matplotlib Critical Error       Energy Line Chart: Check path to CSV file (max() arg is an empty sequence)
   Matplotlib Error                Error in plugin execution runConcurrentThread:

Some of that is from before I tried changing state, but a lot of it is the same after.

EDIT: OK, I think that was because I wasn't using CurrEnergy, instead I was using the .ui. But I've still got red and lots of it. looks like all I got rid of is

Code: Select all

 Matplotlib Critical Error       Energy Line Chart: Check path to CSV file (invalid literal for float(): 1977.140 W)
 

And another edit: realized what I was doing wrong with

Code: Select all

IOError: [Errno 2] No such file or directory: u'/Library/Application Support/Perceptive Automation/Indigo 7/IndigoWebServer/images/controls/static//Users/macadmin/Pictures/ChartEnergyLine.png'


and have fixed that, I think. Much much less red, but still:

Code: Select all

Matplotlib Warning              Invalid Indigo ID. invalid literal for int() with base 10: 'None'
   Matplotlib Critical Error       Energy Line Chart: Check path to CSV file (invalid literal for float(): 1977.140 W)
   Matplotlib Critical Error       ValueError: ordinal must be >= 1


Also, just went into the CSV and removed bad data from when I was using CurrEnergy.ui, so now I'm getting this:

Code: Select all

FINAL EDIT: I Think I've Got IT. Though clearly, I need to do some tweaking:

Looks like you're on your way.

Some of the weirdness that you're seeing in the chart is because of the plugin restarts. Every time the plugin restarts, it's going to grab a new value and save it to the CSV file. You've got some that are several times per minute. That will give you a LOT of observations. All your data is within 20 minutes and the plugin's shortest window is once every 15.

Second, it looks as if you have annotations turned on. I highly recommend only using annotations when there are a few observations--like a weather forecast.
