ultimonitor's Issues

SMTP setup is fragile

Since I'm not running printzini in a container during debugging, and restricted the dirtymail net to the docker subnet and lowell subnet, I can't reliably figure out a way to reference the damn server in the configuration file. Super annoying.

Consider a database

I could do the temperature statistics way better and just have an async process in another container that just grabs the temperatures, all the time, and stores them in a time windowed database. It would then be a better match with the developments that have occured with Mr. Freeze, and not that much overhead considering everything can just still run on the Pi.

I'm almost tempted to say that it might be better to consider another database, but influx makes this so easy it's probably not worth that extra effort.

gcode scraping

When I detect a print, should I download and parse the gcode to pull out print-specific parameters and put them in the summary? It can be done, probably pretty easy, since Cura annotates the gcode.

Seems like /print_job/gcode or /print_job/container would do it, though I think they require API authentication so there are some under-the-hood workarounds to do too.

Figure out passwords

A continual thorn in my side. I just need to figure out how I want to do this, and then just do it.

A previous cobbled-together solution I came up with for DataServants has the passwords in another file that is then associated with the main config file. But I hate that. I really, really, really just need to figure out whether I want to put the credentials in environment variables that are pulled in for each container (ugly for Alfred with his many machines to check) or if I do encryption and just keep the keyfile secret/uncommitted.

The second seems sensible, but I'm no security expert.

Unhandled timestamp exception

While printing, I'm missing something occasionally. Not sure why this happened yet:

At that point, Printzini restarted, so the emails were sent again. Not ideal.

Seemed to occur this morning, too:

I think this one is because when the printer errored out (and entered wait_user_action) the same data isn't returned. I don't hit that failure mode often, but I should trap for it at least it seems?

Account for network interruptions

Printer was rebooted this morning, which caused an unhandled exception in this monitoring code because queries via apitools.queryChecker failed (and were handled) and returned empty dicts, which caused KeyError later when other bits tried to access the juicy information in them.

Strange failure querying hotends while in progress

Not sure if this is just a "busy" sort of signal from the ultimaker API or something, but I am seeing more failures along these lines:

Looking at the lines in question

Ultimonitor/ultimonitor/printer.py

Lines 232 to 238 in 14afe43

	bedtemp = api.queryChecker(printerip, "printer/bed/temperature")
	if bedtemp != {}:
	ext1temps = headinfo['extruders'][0]['hotend']['temperature']
	ext2temps = headinfo['extruders'][1]['hotend']['temperature']
	else:
	ext1temps = ""

I can just wrap them in a try...except block and see what comes out after that. Has happened once a day for the last 2-3 days now.

Saved state

Save the state of the print currently being monitored to a json file on disk (or something) to allow persistence of info between code restarts. Only way to avoid duplicate notices.

Could make the file a sort of snapshot of progress/parameters, too, which might be nice. Needs a little more thought.
