After today's update of the xiaomi_miot_auto integration, I encountered an issue with a missing entity that previously allowed me to turn the Xiaomi Air Purifier Compact 4 (identified in Home Assistant as xiaomi.airp.cpa4) on and off.

Details:
Device: Xiaomi Air Purifier Compact 4

Integration version: xiaomi_miot_auto (update performed today)

Problem:

After the update, I can no longer find the entity responsible for turning the device on and off.

Despite receiving a message that the entity is unavailable, the device still responds to actions such as turning on or off when clicked in the UI.

Logs:
Here is a log excerpt showing the error related to the device after the update:

My questions:
Is there any configuration change required after the update to restore the entity?

Is there a way to regain full control over turning the device on/off, possibly by manually restoring the entity?

Request:
I would appreciate any assistance in resolving this issue or any guidance on how to work around it.
