Gateway Identification Practical Guide

[anotherjulien]

A new Practical Guide, Identify an OpenWebNet Gateway, has been added to the Encyclopedia as a specialized instance of Read and Present a Device Configuration.

The guide addresses a recurring problem: reliably determining the catalogue identity of an unknown OpenWebNet gateway from protocol traffic.

The key finding is that WHO 13 DIMENSION 15 cannot always identify a gateway uniquely. In observed captures, both an MH202 and an F454 return DIM15 = 200. The guide therefore continues identification through diagnostic WHO 1013 DIMENSION 1, which returns OBJECT_MODEL, N_CONF, BRAND, and LINE.

It then shows how to resolve OBJECT_MODEL, BRAND, and LINE against MHCatalogue.db, using the Integration Functions catalogue context, to obtain the corresponding EN_DEVICE catalogue identity and SKU.

The MH202 and F454 captures are included as worked examples, demonstrating how the same DIM15 value is disambiguated by OBJECT_MODEL = 5 versus OBJECT_MODEL = 51.

The guide also makes the evidence boundaries explicit: it keeps WHO 13 DIMENSION 15 and diagnostic DIMENSION 1.OBJECT_MODEL as separate namespaces, does not infer unsupported compatibility behavior, and treats missing diagnostic responses or catalogue matches as unresolved rather than guessing.

Relevant Practical Guide navigation and the WHO 13 / diagnostic DIMENSION 1 reference pages were updated to point to the new workflow.
