How to report the "System Node Temperature" for a specific node in OS? I am thinking about using AddOutputVariable measure, but it seems I can only input the variable name and get temperature for all nodes.

In EnergyPlus, I input the node name in the "Key Value" item of the "Output:Variable" section. Where could I input the node name in OS? I am using OS1.7.0.

Here is a measure where you can pick an airloop or plant loop, specify whether you also want demand nodes (it'll include the supply nodes by default) and to pick which output variables and the frequency you do want and it'll add them for all the requested nodes: BCL

I don't think there is an existing Measure on the BCL that will do that, but here is one that I use for my own purposes. You enter a node name and a reporting frequency and it will give you all of the important state information for the node including temperature, flow, and humidity ratio (if it is air).

We should probably update the generic add output variable measure to have a field identifying which object to add, which could be single object or all objects.
