This is certification blocker for us.

@dhrishi @VaishaliAvhale can you please look into this and others I created they are certification blockers for us.

Multiple identical endpoints now have to be differentiated via TAGs in the descriptor. This requires a enabling the TAGLIST feature on the Descriptor cluster.

#1141

@jonsmirl Thanks. From where I can find namespaces required for TagList, link mentioned in specification is not public:
https://github.com/CHIP-Specifications/connectedhomeip-spec/blob/master/src/namespaces

[bilalahmaddev]

Got it there is a document for it in specification documents.

[bilalahmaddev]

which namespace should be used for endpoints of type on off plugin and dimmable plugin?

[jonsmirl]

I don't think it matters, they just have to be different.

[bilalahmaddev]

@jonsmirl is this a correct way to add Tag to each endpoint descriptive cluster TagList:

const Descriptor::Structs::SemanticTagStruct::Type ep0TagList[] = {
{.namespaceID = 0x00,
.tag = 0x00}};

const Descriptor::Structs::SemanticTagStruct::Type ep1TagList[] = {
{.namespaceID = 0x01,
.tag = 0x01}};

did this for each endpoint

cluster_t* descriptor = cluster::get(output_channels_endpoint, Descriptor::Id);
descriptor::feature::taglist::add(descriptor);

SetTagList(0, chip::Span(ep0TagList));
SetTagList(1, chip::Span(ep1TagList));

I am not getting any cluster id in logs:

Looks like issue with descriptive cluster:

My bad I was calling SetTagList() before matter started. closing as issue is fixed.
