How do default automation condition sensors work with auto-materialize settings?
Last updated: October 22, 2025
The default_automation_condition_sensor is automatically created for a code location when all of these conditions are met:
The code location has assets with AutoMaterializePolicy or AutomationCondition
You are using Dagster version 1.5 or higher
The code location successfully loads and registers definitions
To enable automation condition sensors:
Set
use_sensors: truein your auto_materialize configurationEnable the desired sensors in the UI
Note: Simply enabling sensors in the UI without setting
use_sensors: truewill not activate the automation
When troubleshooting missing default automation condition sensors, verify:
Your Dagster version is 1.5+
The code location has assets with automation policies
The code location is loading successfully
The auto_materialize configuration has
use_sensorsset to true
