To add a WMST layer via PyQGIS you will need to pass "type" parameter
with value "wmst", "temporalSource" parameter and
"timeDimensionExtent" parameter with the temporal extent value in the

when QGIS find "type=wmst" in URI, it looks for the
"timeDimensionExtent" parameter value to create the provider temporal
capabilities.
Ah, thanks, that was my missing uri information!!
For your case
it fails to find the parameter and while parsing the extent it
crashes, this is a bug, we need to open an issue and address it.
I created
https://github.com/qgis/QGIS/issues/43158
I thought to use the provider defaults (from WMS capabilities), to
be
able to for example change/set the temporal extent later:
layer_temporal_props = layer.temporalProperties( capabilities )
but... I cannot get to the WMS capabilities... (@Matthias: THAT is
was
searching in the api :-) )
You can achieve that by using layer_temporal_props =
layer.temporalProperties(
).setDefaultsFromDataProviderTemporalCapabilities(capabilities)
I tried the setDefaultsFromDataProviderTemporalCapabilities method, but
untill now I'm unable to pass it a capabilities object. The
'capabilities()' from a (wms)layer return you an integer, and I think
that the mCaps of a WMS provider are private?
For WMS layers it would be handy if there would be a way to retrieve the
layer specific information from the GetCapabilities document.
In the case of WMS-T it holds essential information about the
time-extent en time-step to be used in configuring it as a temporal
layer.
I will create a wmst layer now based on some external info.
Thanks Samweli,
