Basic Information

For this tutorial we are going to create a temperature alarm. This Alarm will be triggered when the Temperature is over 50 °C. For this example we have a Virtual Item  to represent the actual Temperature Sensor and another Virtual Item to represent the Alarm Indicator .

Condition

To create an Alarm we need a condition that triggers the alarm and one or two actions to be executed when the condition is fulfilled or no longer fulfilled, respectively. In this tutorial the condition is a temperature threshold of > 50 °C. The value of the temperature is a predefined virtual item.

There are two actions, Action on appear will be called when condition state changes from False to True. And Action on vanish will be called when condition state changes from True to Fale. Both of those actions going to change the Value of the Alarm Indicator.

Action on vanish

This action will be called first when Alarm vanished. Here Action will use XCommand function Write to change the Value of Alarm indicator from True to False by writing 0 to item.
