Accumulator types: flexible signal accumulators

With flexible signal accumulators, you can reset a signal based on accumulators on a daily basis or with an input signal. You'll be able to show those accumulators in the Vehicles list.

This is very useful if you for example want to measure engine hours, daily driving time, or continuous driving time.

This example shows how to show both daily driving time and driving time for the latest trip. The input signal Engine is used to count time. The first accumulator called “Today” is reset daily and the second accumulator called “Trip” is reset when the engine is turned off, with a 15-minute delay.

Application setup

Enable the following Privileges in the application.

1. Log in to an application using a Site Admin user.

Device mapper setup

In this example, we will use Ignition as the input that triggers the events we need in the accumulator. 

1. Open the Device Mapper.

2. Go to 4. Scripts and select CustomBoolean1 as the output of the script

3. Click on +Add to add a new script, set a name for it, then click on Edit.

4. Enter the following script: return !fields.get('Ignition',false);

The script inverts the Ignition signal to be used to reset the Trip accumulator later on.
