+## Enable Versatile Thermostat logs
+Sometimes you will need to enable logs to refine the analyses. To do this, edit the `logger.yaml` file of your configuration and configure the logs as follows:
+```
+default: xxxx
+logs:
+   custom_components.versatile_thermostat: info
+```
+You must reload the yaml configuration (Dev Tools / Yaml / All Yaml configuration) or restart Home Assistant for this change to take effect.
