States Reset to 0 after HA restart

[broyuken]

After I restart HA, all of my occupanct sensors are set to 0 until they update again. For example, frigate still knows there’s a car in my garage, but the HA integration is back at not detected until I leave and come back again. Is there a way to have it pull states from frigate when HA restarts so these are accurate?

Based on the available sources, there isn't explicit documentation about occupancy sensor state persistence across Home Assistant restarts. The occupancy sensors provided by the Frigate Home Assistant integration rely on real-time detection updates rather than pulling historical state from Frigate when Home Assistant restarts(1).

The integration requires MQTT to be configured and Frigate must be connected to the same MQTT server as Home Assistant for the entities to function properly(1). The occupancy sensors update based on MQTT messages published to topics like frigate/events(2).

When Home Assistant restarts, the sensors reset because they depend on receiving new MQTT messages to update their state. Since Frigate publishes messages when objects change (new detections, updates, or when objects end), a stationary object that hasn't changed won't trigger a new MQTT message to update the sensor after your Home Assistant restart(2).

For automations requiring more accurate state tracking that matches Frigate's actual detections, it's recommended to use MQTT sensors based on the frigate/events or frigate/reviews topics rather than relying solely on the occupancy sensors(3)(4). This approach provides better filtering and more reliable state information that aligns with what Frigate actually detects.

To be clear that feature request is for camera states and is related to Frigate restarting, that won't affect things like the status of home assistant person occupancy counts. For that there is a pinned integration feature request

Ah okay, I figured it'd be at least related.
