I have seen some topic about negative Watt values in PHP.
However 2 of my Circles give a negative value (most of the time, but sometimes they are OK) so the total amount of current kW is not correct in Source. I tried to place them on different locations and different equipment, but still the values given are negative

Does anyone has this same problem or has a solution towards it?
Btw, the firmware of the circles is from date 27-06-2011 and Source version 2.22 attached is the consumprion as in Source
