Initial temperature on energy simulation

Hello,

I am a student currently working on energy simulations using Grasshopper and EnergyPlus.

I have a question regarding this.

I am conducting a validation between measured indoor temperatures and simulated indoor temperatures. However, I noticed significant discrepancies because I did not set the initial indoor temperature for the simulation.

Is there a way to set the initial indoor temperature directly within Grasshopper, rather than modifying the IDF file?

Thank you in advance for your assistance!
