Hi there,

I am still new with mango. Can somebody help me on how can I get a value at specific time (let say 8am) in metadata scripting. This is because I would like to calculate the use of (e.g. energy ) so far from that particular time. Is the below code is fine

return p1.lastValue - p1.pointValueAt(8)

Thanks @mattfox for the information. I will try to explore the things you said.

Hi Gordoe,
The energy consumption in accumulating form

Hi there,

I have data point that read energy consumption (kwH) from a power meter. I would like to know how can I divide the data into off-peak hour consumption and peak-hour consumption. In addition, I would also like to calculate the total consumption for today, yesterday, current month and previous month. I am still quite new with mango. Can somebody assist me on this matter or share any link that can be helpful for solving my problem.
