Hello,
That I have this device measures the instantaneous electrical consumption.
I set the option in order to to send me the data only if there is a difference from previous measurement of 50 watts (it's run correctly).
My problem Is that always sends the measurement every two minutes even if there is this gap.
I Looked at the various settings but can not find anything about it, you know how can I do?
