Examples of modbuspal.generator.Generator

modbuspal.generator.Generator
A generator creates a dynamic value to be used in automations. This class defines the common properties and behaviors of all generators. It must be subclassed in order to customize the "getValue" method, which is responsible for generating the dynamic value. @author nnovic
