If a task plan has triggers per reading, the meters must be linked to each associated asset. To do this, first go to the "Linked Assets" tab and select the asset to which the meter is to be configured (this procedure can be performed for each of the assets associated with the plan independently).
When clicking on edit, a new window will open in which all the task configuration tabs will appear (Calendars, Triggers, Subtasks, Iterations), in which case the Triggers or Subtasks tab must be selected (depending on where the meters are added), where all the tasks with triggers or subtasks associated with the meter reading will be displayed.
Then, just select the task in question and the system will display a window where you can create a meter or select an existing one (in case it has been previously created from the meter module). Finally, after linking the corresponding meter for each task, click on the "Save" button to make the changes.
