 ### Deployment
 After committing and pushing changes, deploy blueprints to Home Assistant:
 ```bash
-HA_POD=$(kubectl -n ha get pods -l app=ha-app -o=jsonpath="{.items[0].metadata.name}")
-kubectl -n ha exec "$HA_POD" -- bash -c "cd /config/blueprints/automation/rzen && git pull"
+labctl blueprints:pull ha      # from the lab repo; runs git pull in the checkout on the ha volume
 ```
+Then reload automations in the Home Assistant UI (Developer tools → YAML → Automations) so blueprint changes take effect.
 
 ### Testing & Validation
 - **Blueprint Validation**: Use Home Assistant's built-in blueprint importer to validate YAML syntax
