Response (json):

[{ "code": "System_01", "measurementName": "Temperature", "tag": "DEMO_02TI301.PV" }]

Multiple assets with DataFrame output

measurements_df = model.getMeasurements(
    ["System_01", "System_02"],
    output="df",
)

code	measurementName	tag
System_01	Temperature	DEMO_02TI301.PV
System_02	Temperature	DEMO_02TI201.PV

Filter by measurement type

measurements = model.getMeasurements("System_01", measurement="Temperature")
