Device type and model

Dehumidifier

Used App

Home Assistant

The description of problem

I have the same issue covered under the umbrella of "unable to start after update to 2025.1.0" but a different error message:

Setup failed for custom integration 'midea_ac_lan': Unable to import component: cannot import name 'TIME_DAYS' from 'homeassistant.const' (/usr/src/homeassistant/homeassistant/const.py)

This seems to be due to TIME_DAYS being depreciated - notes in the source code says:

"""Deprecated: please use UnitOfTime.DAYS."""

EDIT: These and possibly others are all used in the integration and have been decreciated to new constants

TIME_DAYS
TIME_HOURS
TIME_MINUTES
TIME_SECONDS

EDIT 2: Seems like all have been updated to new values with the exception of PERCENTAGE

I'm having the same here. Will be waiting for a fix.
Thanks for reporting.

[fangming828]

我这里也遇到了同样的问题。请大佬修复。
谢谢。

[jesterod]

Same issue had to downgrade HA core

[vergil-zhao]

Just submitted a fix PR, you can also replace all deprecated constants by yourself. Changes in the PR above.

[ThemeIT]

Your PR works like a charm, thanks :)

[pcmike]

Same, waiting for this update to go live

[superpower10]

So we wait for a HACS Midea update? Right?

[deenx]

same here after update HA 2025.1.0

i would suggest updating your local copy of the repo through a HA file editor.

All necessary updates can be seen here: 3bd4cf1

Just add the changes to your local files to: /homeassistant/custom_components/midea_ac_lan/... (and there are 3 python files to be changed)

I have a gut feeling that this PR will be unanswered for quite some time as the repos original maintainer seems to be absent

also you could use this guide -> #635 (comment)

[mf76130]

just went through it to correct mine, seems there are these 2 not changed:
CONCENTRATION_MICROGRAMS_PER_CUBIC_METER,
CONCENTRATION_PARTS_PER_MILLION
and cause an error.
Trying to figure out what to change them to.

Edit: In the meanwhile i just imported the files via terminal and now it doesn't care about these constants anymore!

thanks a lot for the work

This reporistory is dead because the maintainer has not been available for a long time and no more pull requests are being merged. You should switch to https://github.com/wuwentao/midea_ac_lan.
