It would be useful to be able to filter entities in the unused entities panel similar to the states dev panel.
Unless I am mistaken this can be done in the new Lovelace ui by clinking on the 3 dots in the upper right corner.
Well, that is how you reach the “unused entities” panel, but it has no possibility to filter for a subset of entities.
Ah, I understand. One thought I had, not sure if it is possible but using a monster-card. to filter unused and whatever other condition. I have been thinking about doing this, however I don’t think that is something currently available in the custom card, not sure how easy it would be to add either. But maybe an option.
