1. Function library

The functions below are divided into three main groups:

• General: Functions that can be utilized in both Horticulture and Manufacturing contexts. This includes the categories of Statistic, Time and Logic
• Manufacturing: Functions that are typically used in Manufacturing.
• Horticulture: Functions that are typically used in Horticulture.

2. Formula structure & components

Within an Opera formula, you'll notice various color codes designed to assist in distinguishing the type of each component that contributes to the complete formula.

• Green - Functions
• Blue - Numeric values
• Purple - Sensor metrics, the data that can be read only. They are recorded data from your sensors or existing system, and cannot be modified in Control Center.
• Magenta - Setpoints are data that can be both read and written. Typically, these setpoints are identified by having the letters Sp or U prefixed to their names. They are the type of data that can be modified in Control Center.
• Orange - Calculation metrics, aka user-generated metrics, which often include complex calculations and can provide better insights compared to raw data from sensor metrics. (more information: Calculation metrics)

A more complicated formula often comprise several expressions. You can consider them as the building blocks of your formula to produce a result. Each expression can consist of multiple functions.
