Unavailable Entities after update to 2025.12.3

Configuration

Hi, hope someone can offer advice on this.

After updating to 2025.12.3, I constantly get a notification about a large number of Unavailable Entities. Some of these are “real” and such that I could delete them. But still very many remain that either are of the type that:

  1. become active in some situations (e.g., time remaining of a dishwasher program, which only appears when the program is running), which I never used to get a warning about.
  2. seem to be entities that are no longer exposed through the integration in question (e.g., tire pressure of the Volvo car connected), but there is no way to delete them.

I can always make them invisible, but it does not stop these notifications.

Is there any way to get rid of these entities or automatically generated notifications?

I think there was a mention of deprecated items and what to do in the update release notes.

I tried reading through the release notes now, but can’t really see any advice on this?

There’s nothing in HA that will create warnings when entities are unavailable. There’ may be things in your logs that do this, but that’s it.

Can you clarify what you mean here?

A sensor that flags entities with a status of “Unavailable”, or just excludes them from further processing by status condition checking? Post your code
