Hi everyone,

I had use EMS:Sensor to record the Relative Humidity Value of Zone like below:

EnergyManagementSystem:Sensor,
 WestZoneRH,
 West Zone Air Node,
 System Node Relative Humidity;

However, when I print the Output Relative Humidity like below and these values did not match with each other in the same timesteps.

Output:Variable,West Zone,Zone Air Relative Humidity,timestep;

Output:Variable,West Zone Air Node,System Node Relative Humidity,timestep;

Can someone find where the problem is and give me some advice?

Thank for all your supports.

However, when I print the Output Relative Humidity like below and these values did not match with each other in the same timesteps.timesteps (example: 20.88% vs 22.52%, 15.68% vs 16.5%, etc. Sometimes it different about 5%). When I record the temperature of the Zone by EMS: Sensor, the values were matched.

Output:Variable,West Zone,Zone Air Relative Humidity,timestep;

Output:Variable,West Zone Air Node,System Node Relative Humidity,timestep;

Can someone find where the problem is and give me some advice?
