[Bug]: sensor: state_class_removed for all humidity sensors

[coreGreenberet]

Describe the bug

After upgrading to HomeAssistant 2024.10.0 I'm receiving this warning for all humidity sensors:

sensor.luftfeuchte Verfügt nicht mehr über eine Zustandsklasse
sensor: state_class_removed

Firmware of your Miniserver

HomeAssistant install method

HASSIO

Version of HomeAssistant

2024.10.0

Version of Pyloxone

0.6.15

Update pyloxone

is already latest

@coreGreenberet is it a normal sensor or a custom sensor.

[coreGreenberet]

It's the normal touch tree

Now there is more info in the "repair" part of HA:

We have generated statistics for 'Luftfeuchte' (sensor.luftfeuchte) in the past, but it no longer has a state class, therefore, we cannot track long term statistics for it anymore.

Statistics cannot be generated until this entity has a supported state class.

    If the state class was previously provided by an integration, this might be a bug. Please report an issue.
    If you previously set the state class yourself, please correct it.[ The different state classes and when to use which can be found in the developer documentation.](https://developers.home-assistant.io/docs/core/entity/sensor/#long-term-statistics)
    If the state class has permanently been removed, you may want to delete the long term statistics of it from your database.

Do you want to permanently delete the long term statistics of sensor.luftfeuchte from your database?

looks like it is missing state_class: measurement

@coreGreenberet humidity sensors does not get a state class by default. You have to set it if you want to use the statistics. It is not a bug. I have at the moment no possibility to set the state class correctly for humidity sensors.

I can confirm this behavior for:
humidity sensors and the battery capacity of door/window contacts
@JoDehli PyLoxone could the state_class for both to "measurement" to fix the issue, correct?

[JoDehli]

@hatl
@coreGreenberet

Of course this would fix the problem.

Why is it not so easy to automatically assign all the needed parameters:

When a sensor is created I need the information what sensor type it is. For example a Temperature
sensor. I the unit is formatted right on the loxone side i can try to parse the unit and guess that it is
a temperature sensor. But with the humidity and the capacity of a battery there is only the % as unit.
In the past I guessed the % unit as a humidity sensor and some people had the problem with there battery
sensor showed up as humidity sensor.

So I do not really see a perfect way to solve this problem for all users. The only way to solve it at the moment is
to it manually for each humidity or battery sensor.

@hatl @coreGreenberet

can you try the version from the 306-bug-sensor-state_class_removed-for-all-humidity-sensors

I tried to set at least the state_class to measurement for both types of sensors.

[coreGreenberet]

Warnings in HA are gone and so far everything is working =)

thanks

[hatl]

I can also confirm: warnings are gone - thanks!

[JoDehli]

@hatl @coreGreenberet

I integrate it in the next release.

Thanks for your help.
