Two PetKit device cards for a feeder and a water fountain, with sections for controls, sensors and diagnostics

The situation

PetKit devices expose a lot of controls, sensors and diagnostics. For a feeder or a water fountain, the thing that matters is seeing a problem quickly, and a raw entity list doesn’t help with that.

What I built

A device card that sorts a PetKit device’s entities into controls, sensors, configuration and diagnostics, flags problems with a warning state, and has a pet portrait mode for people who want the cat on the card.
