Hi all,

I have a Honeybee model connected to a HB Model to OSM component.  
The model is previewing correctly in Rhino as far as I can tell.  
When I try to run it, I get the following error.

1. Solution exception:  
Failed to import honeybee\_energy:  
Cannot import name to\_openstudio\_sim\_folder

A screenshot is shown below.  
I have used the Pollination installer for the full installation and I have also run the HB Validate Model with no issues.

Any assistance will be appreciated.

Solved. I used the v1.8.2 component instead of v 1.8.0. Needed to revert to v1.8.  
Alternatively, one can use the latest pollination installer which should be compatible with OpenStudio 3.9
