The KNX integration uses a specific enumeration to extract field values in a compact (raw bitmap) format. It is represented by field point parameter 3. The KNX programmer provides the EIS or DPT type for all groups handled by the Metasys system. Table 1 shows the relationship between the enumeration and the EIS and DPT types.
