Re: Battery Charting Script

Thanks for the colorful information, great tool!

Code: Select all
plt.figure(figsize=(0.5,0.5))


What is the smallest circle which could be made?
Because 0.1,01 give a square.

Re: Battery Charting Script

It's probably not a square per se; it's probably plotting a circle that's larger than the figure area.

If you reduce the figure size, you need to reduce the plot size too. Try playing with the s=300 bit.

Re: Battery Charting Script

I figured I'd try this, haven't done any scripting within Indigo yet..

Indigo 7.4.1
macOS Catalina 10.15.4

Created a New Schedule
Under Action Execute Script (Scripts and File Actions)
Copied the script from the git hub repo, tried it in an embedded script, got Invalid Syntax
Saved it to a file battery-charting-script.py in the /Library/Application Support/PerceptiveAutomation/Scripts, and choose it as the file to run, got
Script Error battery-charting-script.py: invalid syntax
Script Error around line 349 - "print(s, file=self.fileo)"

Which script did you use? The one linked to in post 1 of this thread is only 143 lines long and I don't think it contains any print statements.

Re: Battery Charting Script

That one for the first post.
https://github.com/DaveL17/indigo-scrip ... -script.py

yes it is only 143 lines long, very confusing.

Re: Battery Charting Script

I think something strange may be happening with the code that you pasted into the script window. I just copied the script from Github into a new embedded script window, changed the image file save path to Indigo 7.4 for my version, and selected run. The script ran without error and generated an image file to the target folder. Try copying this script instead:

Code: Select all

# -*- coding: utf-8 -*-

try:

Re: Battery Charting Script

Got the same error,
Maybe something to do with how Indigo is mapping running scripts in python and outputting the error info?

Re: Battery Charting Script

What version of Indigo are you running?

Also, please provide the entire error message. There's no print statement in the script, so I need more to go on.

Re: Battery Charting Script

I think I figured it out..
leftover file from homebrew.
~/Library/Python/2.7/lib/python/site-packages /homebrew.pth

Removed that and it is working!

Now that I get an image, I assume I have to add a Control Page that uses that image or something?

Re: Battery Charting Script

Glad to hear you were able to find the cause of the problem. I would likely have never been able to figure out Homebrew was the culprit.

The purpose of the script is to generate an image for control pages, but that's not necessarily the only way to use the product of the script. For example, you could add the image as a shortcut to Safari (for periodic inspection), or email the image to yourself every so often using the Better Email plugin.
