Hey everyone,

I've been using Honeybee to validate my model for the EUI and thermal comfort. I had to validate the model for adaptive thermal comfort with natural ventilation run using CO2 sensors. I realised the best way to do that would be using the EMS. I've come across a few discussions talking about the same issue along with some executed EMS codes. I believe I would need to use the IDF editor to run this code. I'm new to EMS, could someone direct me to a detailed explanation of how to use this? As I need to set up sensors for multiple zones, I'm very confused about how to go about it. I would appreciate any help I could get :)

Update 01:

I was able to figure out the EMS script for CO2 sensor control. As I am writing the script using IDF editor, I don't have the option to loop all the windows together leading me to include all the windows in the script. Here is where the problem arises. I encounter errors when I try to run the _idf file on honeybee. Invalid names for Actuators as below. This is only a small part of the error.

Below is the script that I'm using for the CO2 sensors.
