Temperature Warning

This example triggers a notification when a measured temperature rises above 28 °C.

Required blocks

  • A sensor or device block that provides the current temperature
  • Compare Values
  • A notification or other action block

Program flow

Temperature sensor → Compare Values → Notification

Configuration

  1. Add the temperature source, Compare Values and notification blocks to the workspace.
  2. Connect the current temperature to input a of Compare Values.
  3. Enter the fixed value 28 at input b.
  4. Select the operator a > b.
  5. Connect the Boolean output to the notification condition.
  6. Configure the notification text, for example Temperature limit exceeded.

Result

At temperatures up to 28 °C, the comparison returns false. Above 28 °C, it returns true and the notification is triggered.

Variation

Replace the notification with another action to switch on cooling or reduce a heating setpoint automatically.
