Create Rules
OpenRemote has its own rules engine that can be utilized for a broad spectrum of tasks, ranging from simple attribute linking to complex algorithms, such as predictive models. There are three different types of rules you can choose from: When-Then Rules, Flow Rules and Groovy Rules. On this page you will find a brief description of each type, along with references to their dedicated pages for more details and examples.
When-Then Rules
When-Then rules are used in combination with the or-rules UI component. They are meant to be used to allow application users to define 'When this, then that' statements. For example "During weekdays, when it's cold, turn on the lights 5 minutes before sunset" or "send push notification to anybody who reaches the stadium".
Flow Rules
Flow rules are mainly intended for attribute linking and processing existing attributes, translating them into new virtual attributes. They can also function as regular event rules. They're useful for users who want to create rules in a visual manner but also need to define rules more complex than is possible in the When-Then (JSON) rules UI editor.
Groovy Rules
Groovy Rules are written in Groovy, a programming language that can seamlessly work together with Java. These rules are capable of performing any task that OpenRemote allows rules to do and are intended for scenarios too complex to be defined by When-Then Rules or Flow Rules. Users with programming experience may prefer to write rules in Groovy, regardless of their complexity.
Forecasting
OpenRemote includes two types of time series forecasting methods for attributes, one quick and simple, based on weighted exponential averaging, the other using a machine learning based non-linear regression model.
GeoJSON Geofencing in OpenRemote Rules
This document describes how to use GeoJSON geofencing within OpenRemote Rules to create location-based triggers and actions. GeoJSON geofencing allows you to define complex geographical areas using the GeoJSON format and trigger rules based on whether an asset is located within or outside these areas.
