To facilitate the swift and efficient replication of formulas across various zones and compartments, we introduce the notion of template metrics and auto-metrics.
In a greenhouse, you will often see the same type of sensors/metrics and control setpoints in different compartments, zones or sites. The metric relative humidity in compartment 1 will share the same template as relative humidity in compartment 2.
Figure 1. Template metric of a sensor
Figure 2. Template metric of a setpoint
The templates follow their respective metric’s colors. In the example above, the relative humidity template is represented in purple, while the setpoint heat template is depicted in magenta (more information).
Notably, template metrics are distinguished by a dotted line box surrounding them, in contrast to specific metrics, which lack this border. Specific metrics might also include a numeric suffix in their title, indicating their position or the compartments to which they pertain, as illustrated in the above example. These mapping are automated by our system once the data from your existing control systems are integrated into Control Center. You can check and edit the mapping of these templates in the Variable mapping feature.
Like any other specific metrics, template metrics can be employed in your setpoint control formula.

When you input specific keywords in the formula text area, you'll observe the templates appearing in the suggestive search results alongside other metrics.

After you group the setpoints, you can choose to write the control formula using the template metrics instead of just the normal specific ones. By doing so, you ensure that the child setpoints maintain a consistent formula structure while still utilizing metrics specific to their respective compartments. Additionally, this will streamline the process of modifying your formula in the future, enhancing efficiency.
Let’s look at the example below. We have the group setpoint called SP Min Rail Pipe Temp Comp 1 2, this is a group setpoint created from the SP Min Rail Pipe Temp in compartment 1 and 2. If template variables are used in the formula, you can click on the template RH to see how:
