​What is a trigger?
Triggers enable the advanced sensors in your tracking device to start logging and transmitting data. Setting up your device to register triggers will prompt it to register any occurrence from the sensor in question.
​
When you enable a trigger, you can select either log or transmit the data.
​
If you choose to log the data, the data logs will remain internally on memory of the tracking device and will be uploaded to the Derek Data Portal at the first coming transmission. If you choose transmission, then the data will be available for online analysis immediately.
​
If all triggers are disabled, then the tracking device will only register the minimum and maximum values of light and internal temperature (+ humidity and air pressure for RHTP devices) since last transmission as well as the current values and the position (GPS or triangulation) at scheduled transmission time.
​
This means that if you want acceleration data, such as motion, shock, tilt, or rotation, then you need to enable the triggers.
​
This page aims to help you with the configurations. If you need additional help or seek more advanced configurations, do not hesitate to contact us.
​Important to keep in mind
Keep in mind that transmissions reduces the battery life of your tracking device more than log.
​
A trigger is not to be confused with an alarm. If you want to be notified by email or SMS when triggers are registered, you should set up an alarm.
​
If there are triggers described in this article that you do not see on your device, it is because you do not have the permission for that trigger. Please contact your manager or your Trusted supplier if you wish to get the permission.
​Motion
The built-in accelerometer registers if the tracking device if moving or not.
​
This is a useful sensor if you want to follow the position of your asset on a map, or if you want to get notified if your asset is in motion.
​Motion log
Set the Motion trigger on Log if you want to log motion data from your device, but do not need the data sent to the server immediately.
​
Select how often you want the device to log the motion from the drop down menu.
​
For example, you can set the trigger to log a position every 10 minutes. Then you can follow your asset with a “breadcrumb trail” at the selected interval.
​
If you set the trigger to once, then it will only send a position when the asset starts moving and when it stops.
​
When the trigger is enabled, your device will register the time of start and stop of the motion by default (standard setting is a stop-position after 5 minutes with no movement).
​Motion transmission
Set the Motion trigger on transmission to send a position to the server when the tracking device is moving.
​
Select how often you want a transmission when the device is in motion from the drop down menu.
​
For example, you can set the trigger to transmit a position every hour when in motion. Keep in mind that frequent transmissions will reduce the battery life time.
​Tilt
The built-in accelerometer registers if the tracking device is tilted or not.
​
This is a useful sensor if you want to know if, where and when your asset has been tilted and with how many degrees.
​Tilt log
Set the Tilted trigger on log if you want to log tilt data from your device when it has tilted more than a selected degree.
​
Enter the tilt angle in the grey box. In this case, a log is stored when the device is tilted more than 30 degrees.
​Tilt transmission
Set the Tilt trigger on transmission if you want the data transmitted to the server immediately when the device has been tilted more than a selected degree.
Enter the tilt angle (10-170 degrees) in the grey box.
​Shock
The built-in accelerometer registers if the tracking device is exposed to a shock, based on G force.
​
This is a useful sensor if you want to know if, where and when your asset has been exposed to a shock and to which degree.
​Shock log
Set the Shock trigger on log if you want to log shock data from from your device when it is being exposed to a certain degree of G force.
​
Set the trigger level in the grey box. In the example, all shocks of a level above 3.1 G will be logged on your device.
​
Defined trigger level can be set between 1,5 G to 8,2 G, but the device can endure much higher G levels.
​Shock transmission
Set the Shock trigger on transmission if you want the data transmitted to the server immediately when the device has been shock more than a selected G level.
​
Set the trigger level in the grey box. In the example, all shocks of a level above 3.1 G will be transmitted to the server immediately.
​
Defined trigger level can be set between 1,5 G to 8,2 G, but the device can endure much higher G levels.
​Light
The light sensor is installed behind the two diodes and is evaluating every minute if the device is exposed to light or not.
​
At every transmission, you will be able to see the minimum and maximum light value since last transmission.
​
Set the Light trigger on log if you want to evaluate the minimum and maximum light data every second. The trigger level defines the minimum light level that should be evaluated.
​
Set the Light trigger on transmission if you want the data transmitted to the server immediately when the device is exposed to a light level that is higher than the trigger level which in this example is 15%.
​Temperature
The internal temperature in the device is evaluated every minute.
​
At every transmission, you will be able to see the minimum and maximum temperature value since last transmission.
​
If you want more temperature data, then you can use the log or transmission function.
​Temperature log
Set the Temperature trigger on log if you want to log temperature data from from your device when it is being exposed to internal temperatures higher or lower than your trigger level.
​
Enter the temperature lower and higher limit in the grey boxes.
​
In this example, the device will log data if the temperature moves outside the determined range between 0 and 40 degrees Celsius. You can also choose to set below or above limits only.
​Temperature transmission
Set the Temperature trigger on transmission if you want to the temperature data from from your device to be transmitted to the server immediately when it is being exposed to internal temperatures higher or lower than your trigger level.
​
Enter the temperature lower and higher limit in the grey boxes. You can also choose to set below or above limits only.
​Humidity
In Derek RHTP devices, there is a built-in humidity sensor that evaluates the humidity level every minute.
​
At every transmission, you will be able to see the minimum and maximum humidity value since last transmission.
​
If you want more humidity data, then you can use the log or transmission function.
Humidity log
Set the Humidity trigger on log if you want to log humidity data from from your device when it is being exposed to humidity levels higher or lower than your trigger level.
​
Enter the humidity lower and higher limit in the grey boxes.
​
In this example, the device will log data if the humidity level moves outside the determined range between 30% and 70%. You can also choose to set below or above limits only.
​Humidity transmission
Set the Humidity trigger on transmission if you want to the humidity data from from your device to be transmitted to the server immediately when it is being exposed to humidity levels higher or lower than your trigger level.
​
Enter the humidity lower and higher limit in the grey boxes. You can also choose to set below or above limits only.
Air pressure
In Derek RHTP devices, there is a built-in air pressure sensor that evaluates the air pressure level every minute.
​
At every transmission, you will be able to see the minimum and maximum air pressure value since last transmission.
​
If you want more air pressure data, then you can use the log or transmission function.
​Air pressure log
Set the Air pressure trigger on log if you want to log air pressure data from from your device when it is being exposed to air pressure levels higher or lower than your trigger level.
​
Enter the air pressure lower and higher limit in the grey boxes.
​
In this example, the device will log data if the air pressure moves outside the determined range between 30000 Pa and 105000 Pa. You can also choose to set below or above limits only.
​Air pressure transmission
Set the Air pressure trigger on transmission if you want to the air pressure data from from your device to be transmitted to the server immediately when it is being exposed to air pressure levels higher or lower than your trigger level.
​
Enter the air pressure lower and higher limit in the grey boxes. You can also choose to set below or above limits only.
Daily schedule
Daily schedule is a feature that enables you to determine a specific daily interval when your triggers should not be active.
​
This is handy if you only need transmissions and alarms in a chosen time frame. It also has the added benefit of preserving battery life.
​
An example could be if you would like the device to send a transmission to the server if your asset moves before 8am or after 4pm, but not during these hours.
​
Enable this feature by switching on the button. Slide the orange buttons in the bar to determine the time frame.
​
If you click Invert daily schedule, then the trigger will only be active during the times that the orange buttons show – in this example between 8am and 4pm.
Configuration pending
You are able to see if your configurations to the device have been applied or are pending.
​
The text will be red when a new configuration is pending.
​
Pending configurations will be applied the next time the device communicates with the server through a scheduled transmission or through a triggered transmission.
​
In this example, the Motion log was already set to Once. After changing it to Every hour, the text turns red. This configuration is now pending. At next transmission, the configuration will be applied.
​How to force a transmission?
​If you wish, you can force through configurations by placing a magnet on the Activate with magnet symbol on the device until the left LED starts flashing red. When the LED stops flashing, any new configurations take effect within 15 minutes.
