Device filter has been removed from target selector

The device filter option is no longer supported by the target selector and has been removed from the target selector documentation.

Hassfest has been updated to fail on services with device filter on targets.

Validation of target selectors that specify a device filter will fail in Home Assistant Core 2026.11.

Background​

Core helpers that extract entities from targets did not support the device filter. When the user picked a floor, area, label, or category, the filter was ignored. The frontend also ignored the device filter when selecting entities for a target.

A review of all core integrations found no correct use of a device filter on target selectors. We removed the device filter from the target selector rather than implement support for it in Core and the frontend.

Impact on custom integrations and blueprints​

Update custom integrations and blueprints to remove device filters from target selectors.
