Previously, I have read that the components can be upgraded if an example file from Hydra is used. In this case, should I upgrade the versions of the components to 1.2.0?
All examples on hydra are currently for Legacy and there’s no automated way to upgrade a Grasshopper definition from Legacy to LBT. I would suggest either manually re-making the hydra definition using the LBT plugin or, if you want to use Legacy, use OpenStudio 2.9.1 instead of the later versions.
