<pre class="header-style">The Battery Temperature trigger fires when the battery temperature increases or decreases to a specified level, or on any temperature change. This is useful for monitoring device thermals and taking protective actions when the device gets too hot or cold.</pre>
</pre>
''' Options '''
Log Event: {battery_temp}
* '''Increase/Decrease''' - Trigger fires when temperature reaches a specific threshold
</pre>
** '''Increases to''' - Fires when battery temperature rises to or above the specified value
** '''Decreases to''' - Fires when battery temperature falls to or below the specified value
* '''Any Change''' - Trigger fires whenever the battery temperature changes
''' Configuration '''
When selecting "Increase/Decrease" mode, you can specify the threshold:
* Use the slider to set a temperature value in degrees Celsius (default is 30 degrees C)
* Alternatively, select a variable to dynamically determine the threshold temperature
* Choose whether to trigger on increases or decreases
''' Variable Support '''
You can use an integer variable to specify the temperature threshold instead of a fixed value. This allows for dynamic thresholds that can be changed at runtime.
''' Examples '''
''Example 1: Overheat Protection''
<pre class="trigger-style">Triggers
Battery Temperature >= 45 degrees C</pre>
<pre class="action-style">Actions
Notification: Warning - Battery temperature high!
Disable Wi-Fi
Set Screen Brightness: 10%</pre>
''Example 2: Log Temperature Changes''
<pre class="trigger-style">Triggers
Battery Temperature (Any Change)</pre>
<pre class="action-style">Actions
Write to File: Battery temp: [battery_temp] at [date_time]</pre>
''' Notes '''
* The trigger listens for the system broadcast ACTION_BATTERY_CHANGED to monitor temperature
* Temperature is measured in degrees Celsius
* The trigger only fires once when the temperature transitions to the new state (for increase/decrease mode), not on every subsequent change where the condition remains true
* The "Any Change" option is useful for logging or monitoring temperature patterns over time
* Not all devices report precise temperature readings - some may report in larger increments
