IoT Data Alert by Pipeline

I am writing a pipeline process to trigger an alert when a temperature sensor exceeds a threshold value.

For e.g. sensor value > 27 °C, it triggers an alert. It is easily to be achieved by Graylog alert configuration. However, when the sensor returns to normal level (say 22 °C), it triggers a 2nd alert. How do I know the sensors issuing an alert before in Graylog?
