Custom Logic
This page describes the Custom Logic Blocks in more detail
Introduction
A Custom Logic Block can be used to evaluate complex logic that can not be implemented with a simple comparison block.
A set of example logic blocks can be found here:
This webinar explains how to create Custom Rules:
Overview
Custom Logic Blocks allow the implementation of more complex business logic with the akenza Rule Engine. They enable simple stateless and stateful operations upon rule trigger using custom scripts in Javascript. Custom Logic Blocks are created on organization-level and are therefore available in all workspaces and can be selected when creating a rule.
A Custom Logic Block consists of a definition of:
Inputs: the dynamic data that is evaluated during script execution (sensor data)
Parameters: constant values like thresholds
A script used to run the logic
Inputs
Inputs specify the input data sources for a Custom Logic Block and contain the dynamic data of a device. At least one input needs to be defined in order to create a Custom Logic Block.
Field
Description
Input display/ label name

Input variable name

Default topic
An optional default topic that is preselected when using the logic block
Default data key
An optional default data key that is preselected when using the logic block
Parameters
Parameters represent static properties that are available during script runtime.
