This happened to me on Monday. The only entities that show anymore are the 3 pets. I have reloaded and reinstalled the integration to no avail. Am I alone ? I wanted to check before I file a bug.
I am also having this problem. I noticed today after installing the 2026.4.2 update (from 2026.4.1), but it could have been the restart that caused it rather than the update.
Edit: looks like there is a fix coming in the next update with a manual workaround here: https://github.com/home-assistant/core/issues/168151
