MQTT Discovery Deprecation: object_id must be replaced with default_entity_id (HA Core 2026.4) #137
Description
The configuration for entity sensor.ac500_dc_input_current1 uses the deprecated option object_id to set the default entity id. Replace the "object_id": "AC500_dc_input_current1" option with "default_entity_id": "sensor.AC500_dc_input_current1" in your published discovery configuration to fix this issue, or contact the maintainer of the integration that published this config to fix this. This will stop working in Home Assistant Core 2026.4
