Using Variables in Tasker With Fire Alarm Macros April 28, 2020

The Tasker application has been made to handle lots of different types of functionality. This post will go into looking at the Set Variable action and then a logic example using the set variable to send fire alarm macros to different devices. Doing this example requires the environmental or temperature sensor to be completed.

The Set Variable Action

Tasker Set Variable Action

The Set Variable Action allows you to create a variable in the first value field of the action, and then assign it a value in the second value field. This is useful when using other control structure actions, such as loops or if blocks.

Fire Alarm Example

Tasker Fire Alarm Example Devices
Note: Values in this example will most likely differ from your.

In this Example, before we create the Fire Alarm Task, we need to create the devices that will receive the macro we send for the fire alarm, like shown above. You’ll also need to the have the Cinema application updated to your JNIOR. To start, go to the device tab and click the “Add Device” button. Add as many Devices as you have JNIORs you plan to send a Fire Alarm macro to. Each device you’ll enter its IP address, and TCP Port number from the Cinema Server Client Registry Key. The Registry Key is under AppData/Cinema/CinemaServerClient/TcpPort in the registry tab of the JNIOR’s webpage.

After creating the devices to send macros to, you’ll start creating the task. It starts with the Set Variable actions. These actions are used to define the values of two temperatures received from a temperature sensor or environmental sensor, and the variable used to know when to end the Task. We define the two Temp variables to values our temperature or environmental sensors are picking up, and the other variable will be set to true as our conditional until the macros get sent. Once these values are defined, a while loop is added to the task. This will check if the conditional of the variable we created is true, which is how we set it so that it will always be looping. After that, we add an if block and set the conditional of it.  This is to determine if the movie theater’s screen room is a lot more hotter then the rest of the movie theater, indicating a possible fire. When the temperature difference is above 20 degrees (indicating a possible fire), using as many TCP send actions for devices you have, it sends to those JNIORs to run their FireAlarm macros. It also sets the conditional for the while loop to false, so the task no longer loops, and ends.

With this, you should have a task that constantly monitors the temperatures of two temperature/environmental sensors, and when the difference between them is greater then 20, sends out the fire alarm macros and ends the task.
