Currently, attributes on entities are treated like second-class citizens. If you would like to display values from attributes, you’re left with two options:
- Get the entity-attributes custom lovelace card, which only gives the option to display filtered attributes in a table.
- Create template sensors for each attribute, which is cumbersome to do, and doesn’t work as expected. Templates are required to have an
entity_idto watch a state for updates, but many domains update attributes without actually updating the state. Using
sensor.timeonly updates every minute, however Home Assistant is aware of the attribute changes the moment it happens; the delay is unacceptable.
Please consider supporting adding attributes directly to entities card so they can intermingle between the two.
