I’m adding a Entity_filter card to track lights and other devices that are on at night time so I can turn them off easily.
In the other purely entity cards, it’s easy to just select the device you want from a dropdown list. With the entity_filter (unless I’m missing something), you have to lookup the entity name, and enter it just like you were working with raw mode. In keeping with the direction that HA seems to be going to make lovelace a user-configurable front end, it would be nice to be able to select the entities from a drop down list and set the state filters similarly.
