I am adding two devices in my gauge, and selecting only one of the attribute out of both devices attributes, as it allows only one to select.
What I want is help regarding the aggregate, as I am selecting “Sum” aggregator, its not summing at all but only showing the value of the attribute I already selected. I have check historic data box too.
What can I do to fix it. I really want a sooner reply. Please
P.s. one device attribute has value of 1, other is 120. Sum should be 121.
