 ### 2. Automation
-**- Notification, Error event**
+
+#### 1) Air conditioner, climate
+
+> - Currently the Climate's set_hvac_mode, set_temperature service is not working properly. Each control must operate sequentially, but conditional wait for this has not yet been implemented in ThinQ integration.
+> - We provide a script that can do turn_on, set_hvac_mode, and set_temperature at once, so please use it for automation.
+> - Create a new script in 'CREATE SCRIPT' using the code below, then select the script in the 'Action' field.
+> - This conditional wait is scheduled to be implemented in core 2025.4.
