+With the **Appwrite** {% term integration %}, you can execute functions in your self-hosted Appwrite instance or their cloud offering.
+
+The integration provides an action in the format `appwrite.execute_function_<instance_id>` which can be used to trigger functions. Multiple Appwrite instances are supported, but each must have a unique project ID in your Home Assistant configuration.
