Trying my first forays into the use of EMS in Ironbug and running into some frustrating problems. I got an error when I tried to run. The SaveToFile component says: “An item with the same key has already been added”
I think the issue is that the Actuator all seems to have the same name. Any way to change the name?
If I disconnect the EMS, there is no error in the SaveToFile component, But when I got an error in the RunOSM file. I copied it down below, but basically all the nodes doing into the air terminals and zones are the ones listed. It looks file in the OSM file, but the IDF does not seem to have any of my zones. When I bypass the RunOSM component and just use the RunIDF from the path out of the ModelToOSM it runs fine (although it does not give me a pathway to add the EMS which is what I am hoping to do when I get it working).
Any thoughts on the inital EMS issue and the reason the RunOSM is not translating the zones to the IDF would be appreciated (seems like it works file when the ModelToOSM is connected directly to the RunOSM but not when it goes through the SaveToFile).
