We have added official support for simulating detailed Ironbug HVAC systems as part of Honeybee models (HBJSON):
With this new capability, you should be able to simulate comfort maps for essentially any case that you would have previously needed to use an edited OSM.
For this reason, we don’t plan on trying to get the comfort maps to accept OSMs as input or trying to find a way to add sensor grids to an OSM (at least not for the foreseeable future).
