So I understand there is only 3 types of points, sensor, cmd, and sp (http://project-haystack.org/tag/point) but it seems we need a few more. That sp can't just be a catch all for everything else. I don't quite get how schedule occupancy status would be a sp but I can live with it.
My problem is we have a zoning system and the zone damper graphic needs to display whether the AHU is in Active heat or Cool. So I have two points on the Zone Damper controller called "AHU Heat Active" and "AHU Cool Active". What tags do I use on these?
I don't really like "ahu heat sp" could be confused with a air setpoint.
Almost need a pseudo point type and a feedback tag or status. Not sure what to call it.
The controller also has a "AHU Heat Call" command so I've used "ahu heat cmd" tags for that.

Really anything that isn't a physical sensor or actuator command should use sp since they tend to be soft/software points.
In your case, I am not sure I understand where the points live. They sounds like they are AHU points that just need to show up on a graphic? If they are essentially just mapping the AHU points then you'd probably want to use the tags the AHU points use
