[homeassistant.util.loop] Detected blocking call to import_module with args

[danielholm]

Hi,

In latest HA 2025.1 I get the following error in logs. The sensors keep working, however.

Interesting
on line 120 i only use dateparser

it's imported on line 11, seems like there's some magic going on where it ignores the imports and then magically imports it whenever it is being used instead

That's kind of a neat trick to not having to import a lot of stuff that is not needed and keeps the scope clean, but in this case it seems to be causing issues rather than helping

Let me look into what i can do about it!

[Reedyn]

I got the same issue. Let me know if you need any information.

[TekniskSupport]

@Reedyn I'm prtty sure this has to do with the time_offset configuration option used on this line:
https://github.com/TekniskSupport/home-assistant-resrobot/blob/master/custom_components/resrobot/sensor.py#L125

But not yet had the opportunity to have a look at the issue

[danielholm]

I would like to help, but its beyond my understanding as of now.

I can confirm, when I removed the time_offset and rebooted Home Assistant the problem went away.
