Hi Tim/Peter, I have updated the ticket. I think at the moment only grib/netcdf supported in gdal can be read as mesh layer.
Here is an example I have prepared for mesh layer, feel free to use this QGIS project: https://www.dropbox.com/s/az6l00c67qq5pzl/mesh_layer_weather.zip?dl=0 There are some bugs (-180, 180 coverage, projection) with mesh, which we will be working on. Feel free to file bugs or feature requests. Will be keen to hear your feedback.
