HA Freeze after couple of hour about homeassistant-ekon-local

[hllhll]

Finally saw this myself, might be misuse/mixup of threads & Async... hope to check this soon

[hllhll]

This might be the issue...
https://github.com/hllhll/pyekonlib/blob/eb1424a0c9242be02f5bc16399f210f8b722f510/pyekonlib/Server.py#L84
Calls self._createAsyncTaskFn which maps to hass.async_create_task in https://github.com/hllhll/HomeAssistant-ekon-local/blob/master/custom_components/ekon-local/climate.py#L161 which should be used to create async task from async. for thread we should use this(?)

[hllhll]

Please try with this fix and report back if you can...

Got a report from one user that so far, problem doesn't persist after the fix :)

it took time, but unfortunately the problem appear after 18 hour :-(

python/asyncio#258

Look like the same problem here

[hllhll]

Why di you think it's necessarily this?
I guess this situatuon might arise from multiple different issue origins.

BTW Do u might have other integration that is async based+threads? That might be due to a conflict originated from a different integration...

[hllhll]

I have installed another integration for my ha
It seem to happen more often.
I assume that having more integrations gives the random-by-nature race condition more chances to occur...

[hllhll]

With the help of a friend, We might have found the issue and fixed it in hllhll/pyekonlib@96d923a and corresponding fix in 0c0b2a9

[hllhll]

I Had this issue again, not sure if it's related to my integration, so I'm re-opening it for the meantime
I plan to implement verbose logging in pyekonlib ...

[hllhll]

Let's see if this helps ...
429cc3a
This is not ideal, because it actually creates another-mostly idle OS thread, but that's my temporary way to circumvent this issue

[hllhll]

The way of implementation for a fix for this in pyekonlib, is not the best.
If someone could go over the code and find the actual issue, I'd like that :)
But when using commit 429cc3a This does not happen again.
