Add New Trend Log

To create new trend log, follow these steps:

1. Navigate to the Trend logs tab in your system.

2. Click the Add new trend log button, located at the bottom left corner.

3. Fill in the Trend log details:
   

   • Object: Choose an object from the list. This object will be the basis for creating the trends.

   • Name: Provide a descriptive name for the trend log.

   • Category: Sort trends into categories for better organization and clarity.

   • Log type: Select the type of log.

     • Counter: Used for counting data.

     • Counter with negative delta: Counts data with alternately increasing/decreasing values (e.g., movement detection from a PIR sensor per hour).

     • Absolute value: Saves the actual readings.

   • Aggregate function: Choose from stored data:

     • Average

     • Minimum

     • Maximum

     • Last value

     This value will be displayed on the graph.

     Each trend stores data for three periods:

     • Every minute (last hour): Data is added once a minute.

     • Custom interval (user-selectable): Data is added at the specified interval.

     • Once daily: Data is added once a day.

   • Trend resolution: The average value of counted samples for a specific time interval will be shown on the trend graph. For example, if the interval is 1 hour, the trend step will be 1 hour with an average of 60 readings.

   • Decimal places: If the object is of floating type, select the desired precision (e.g., 1.1111 = precision of 4).

   • Resolution data: Short-term data storage (Max = 5 years).

   • Daily data: Long-term data storage (Max = 10 years).

   • Always show zero: Leave the option On graph Y axis unchecked if your values never reach zero. For example, consider CO2 levels: If you start at the lowest real value, your trend resolution will appear better.
