E+ Output:Variable - Single VAV Power Consumption

Dear all,

In E+ 9.2.0, I'm wondering if I can output the power consumption of a single VAV box in a specific zone? I want to read this value into my python code at each timestep. So it will be great if I can output this value as a variable. I know we can output its power consumption as a subcategory of meter data. But, I assume this kind of meter data cannot be read at each timestep...

Any comments or suggestions will be very much appreciated.

Thank you for your time.

Best,

Yapan
