Rule Language

The Rule Language is a powerful feature which we use in the Recommender Platform to process event streams, test condition rules, and produce relevant and precise recommendation messages.

Expressions in Rule Language look similar to expressions in Excel or other comparable tools or script/program languages.

To give a first impression, have a look at the following examples, which give an idea how the language can be used:

Examples

Example of a boolean expression which compares multiple values and uses AND/OR operators:

$GridPowerConsumption > 500 AND ($CarChargingMode = 0 OR $CarChargingMode = 4) 
AND $IsLowTariffHours = 0

Example of a text expression, which concatenates static text and dynamic data:

"Heat: " + $HeatCelsius::Value + " °C / " + ($HeatCelsius::Value - 273.15) + " K"
