Detected blocking call to open inside the event loop (HA 2024.6) about nordpool HOT 26 CLOSED

Ill get create a fix for this this weekend.

from nordpool.

I wanted to try but don't have update.nordpool_update so I'll wait for it to be released...

Weird, it should be there if you installed through HACS?

If you did install manually, just download the master branch and overwrite the files in custom_components\nordpool.

edit: thinking of it, it could possible be an experimental feature of HACS (you can enable that in HACS) edit2: confirmed, it's an experimental feature of HACS: https://hacs.xyz/docs/entities/update_entities

You can enable that in HACS configuration: go to your integrations page, click 'HACS' and click 'configure', it's the last checkbox

I finally got to it and just updated it manually for now, blocking calls gone, so all good from my end.

from nordpool.

Confirming that #383 fixes the issues.

For those who wish to try as well: you need to install the master branch of the Nordpool component.

Go to developer tools -> services and run the update.install service:

service: update.install
target:
  entity_id: update.nordpool_update
data:
  version: master

Thanks for report and the links 👍

just saw that it was waiting for a reboot. Rebooting now. I am sure I already did a reboot, so not sure what is happening.
[edit]it is updating now[/edit]

@hiatsu0, the recorder issue is something different and is because you updated to 2024.7, not because of the Nordpool update. See home-assistant/core#117263

Beta 5 throws even more elaborate warnings (probably due to home-assistant/core#118620 being merged for b5), pasting them here for your reference:

Tx. It's just a warning, component still works fine so no worries.

from nordpool.

Hello, how are you?
Can you explain how to fix this 'detected blocking' issue in Nordpool ?

had a look into init.py but don't know what to look for,

thanks

from nordpool.

There's a link in the start post, and otherwise just wait for the next release. It's only a warning, nothing is broken.

from nordpool.

Thank you, I am trying to display 36 hours on an apex chart but it doesn't work, the chart says 'loading...'
It is the code from smarthomejunkie.
Maybe you know a fix? Thanks

from nordpool.

HA becomes unresposive with nordpool - using apexcharts-card in Default dashboard or openening a dashboard with noordpool in apexcharts-card:
But only when using "windows/browser" not with "Android/app" (The dashboard is rendered complete though! And then the browser window needs to be killed.)
Update: The logging is still coming but the HA is responsive today now when no tomorrow values are available.

Another effect of this issue is that it cause very high CPU loads, close to 100% load on one CPU. I was alerted of this issue when I noticed very high loads in HA which runs on a VM. After a bit of diagnostics, found it to be caused by the nordpool integration. I also have the notice in the logs "Detected blocking call to open inside the event loop by custom integration 'nordpool'".

I'm running nordpool 0.14.0 on HA 2024.6.3 on supervisor 2024.06.0.

from nordpool.

This issue might be "only a warning", but it is actually holding up HA for quite some time and clogging up the logs with these warning messages.

Hereby a link to the HA developer blog abut the issue and how to fix it:
https://developers.home-assistant.io/blog/2024/05/19/fix_zoneinfo_blocking_io

from nordpool.

I created this pull request which looks up the timezone without blocking the event loop. There are some other blocking calls though, so this doesn't fix everything.

#383

from nordpool.

Confirming that #383 fixes the issues.

For those who wish to try as well: you need to install the master branch of the Nordpool component.

Go to developer tools -> services and run the update.install service:

service: update.install
target:
  entity_id: update.nordpool_update
data:
  version: master

I wanted to try but don't have update.nordpool_update so I'll wait for it to be released...

blocking calls are gone, but current price is not updating anymore. So not an improvement for me.

That might be something local though, it works completely fine here.

from nordpool.

Is the fix released? I see 0.0.14 from May as latest release? I have the loglines and price is not updating after 2024.6 update today.

from nordpool.

No, it's not released yet. I think that's something @Hellowlol needs to do.

You can update to latest code through the steps in my previous comment.

I have the loglines and price is not updating after 2024.6 update today.

That's unrelated though. The loglines are only warnings, there's nothing broken.

from nordpool.

Current master version worked for me, warnings gone and prices updates still.
HA 2024.6.4

from nordpool.

I have created a beta release as i didnt have time to test all features. Please give it ago

from nordpool.

EDIT: It appears my more severe issues may be linked to other recorder issue (and here), however the latest beta also does not work and prevents HA full startup.

For the record, a confirmed case here as well, with the beta not fully resolving the issues:

Upgraded from 2024.5 to 2024.7 and noticed a severe issue where the cpu utilization would jump from normal <10% to around 50% (2 cpu VM) for a few hours and eventually recorder would get clogged and stop recording.
(This gave some error about "items in queue reaching high number and to save memory, the recorder was stopped" but I didn't save that).

After reboots this kind of errors were common:

homeassistant.components.recorder.util
components/recorder/util.py:331
Recorder

The system could not validate that the sqlite3 database at //config/home-assistant_v2.db was shutdown cleanly

homeassistant.components.recorder.util
components/recorder/util.py:610
Recorder

Ended unfinished session (id=229 from 2024-07-08 19:08:12.034699)

Then I also came across the error in the first post which led me here.

Detected blocking call to open inside the event loop by custom integration 'nordpool'...

Used the update.install service pointed above, and it apprently downloaded the master branch, but after that HA would not fully start anymore until I disabled the nordpool integration. Just got stuck in finalizing startup with this in logs:

homeassistant.components.sensor
runner.py:190
Sensor

Setup of sensor platform nordpool is taking over 10 seconds.

Proceeded to go to HACS to reload the integration, enabled Beta-versions and installed the 0.0.15b0. After this the reboot succeeded (once) but the spot price did not update anymore (notification about "integration not providing this entity anymore"). After second reboot HA got stuck finalizing startup again.

So at least in my case the beta does not seem to function and I think I will need to keep the integration disabled to not mess up the recorder.

from nordpool.

@hiatsu0, the recorder issue is something different and is because you updated to 2024.7, not because of the Nordpool update. See home-assistant/core#117263

Thanks @rrooggiieerr! Was not aware of this issue but indeed looks like that as the problems has occurred at 4:00 last night (though once during the day as well).
