Navet keeps one interaction model across providers without pretending that every provider supplies the same services.
Check the capability matrix
Home Assistant currently supplies the broad advanced feature-service set, including climate, media, camera, energy, calendar, weather, notifications, tasks, history, security, and provider administration.
Homey and openHAB currently supply rooms, live entity state, lighting, switches, and sensors. Hubitat and SmartThings remain planned.
See the current integration capability matrix.
Check the entity itself
Within a supported section, an individual control appears only when the entity reports the required capability. For example, a light without color capability does not receive a color picker.
Check the active provider
Multi-provider installations can aggregate selected entities, but one provider remains active for operations requiring a single advanced feature service. Open Settings → System → Providers and review Active.
Treat connection errors separately
If a normally supported feature disappeared after a connection problem, follow Connection or sign-in fails rather than assuming the provider never supported it.
