Currently, I try to manage to upload value of data point to device cloud and I'm wondering is there any way to compare the value ? What I mean is that is I do not want to upload duplicate value to the device cloud. If the value that I want to upload is difference from the value on the device cloud, the old value will be replaced and if the 2 values are the same, the old value will be kept. Is there a way to do that ?
Thank you for your help
